Detailed Description

In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the disclosed embodiments. However, it will be apparent to one skilled in the art that the present disclosure may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present disclosure with unnecessary detail.

Further, those of ordinary skill in the art will appreciate that the drawings provided herein are for illustrative purposes and are not necessarily drawn to scale.

Unless the context clearly requires otherwise, throughout the description and the claims, the words "comprise", "comprising", and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is, what is meant is "including, but not limited to".

In the description of the present disclosure, it is to be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. Further, in the description of the present disclosure, "a plurality" means two or more unless otherwise specified.

In the field of building construction, a building plane drawing is a drawing formed by a horizontal projection method and corresponding legends according to the building conditions of a newly-built building or the functional layout of the wall, the door and window, the stair, the ground, the interior and the like of the building. The building plan drawing is used as an important component in building design and construction drawing, reflects the situations of plane shape, size, internal layout, specific positions and occupied areas of the ground, doors and windows and the like of a building, is an important basis for construction and construction site arrangement of a newly built building, and is also a basis for designing and planning professional engineering plan views of water supply and drainage, strong and weak electricity, heating and ventilation equipment and the like and drawing a comprehensive pipeline drawing. The construction plan can be divided into a construction plan, a structural construction plan and an equipment construction plan. Floor plans for building construction typically include a floor plan, a standard floor plan, a roof plan, and a roof plan.

During the construction of a building, each process may involve the modification of a drawing, which usually needs an engineering technician to manually perform on professional drawing software (e.g., AutoCAD, SketchUp, 3D Studio Max), and thus, a lot of labor and time costs are consumed; furthermore, because the drawing is drawn manually, the drawing speed of the drawing is slow, and the quality of the drawing is difficult to ensure. In addition, in the subsequent sales process, when the user puts forward personalized requirements, since business personnel do not have drawing making capability, drawing can not be directly modified according to the requirements of different users, but engineering technical personnel are required to be helped to modify the construction plane drawing for many times, so that the drawing making process and the engineering cooperation period are long, and the later maintenance cost is high; furthermore, because the modification of the drawing is completed on line based on the paper drawing, the problems of loss, confusion, damage and the like of the modified drawing are easy to occur.

Therefore, the current drawing modification method mainly depends on manual operation of engineering technicians, and although some products capable of directly deriving the CAD drawing through a graphic engine exist in the market, the products cannot meet the requirements of business personnel. Therefore, a scheme that CAD drawings can be edited and generated on line based on a graphic engine to improve drawing efficiency, reduce professional drawing thresholds of business personnel, and improve sales levels of the business personnel is needed.

Fig. 1 is a schematic flowchart of a drawing generation method according to an embodiment of the present disclosure. The drawing generation method of fig. 1 may be executed by a server or a terminal device. As shown in fig. 1, the drawing generation method includes:

s101, receiving a drawing generation instruction, wherein the drawing generation instruction is used for indicating the generation of a drawing of a target area and comprises a target area identifier of the target area;

The drawing may be a construction drawing, including but not limited to a construction section, a construction plan, a general construction plan, a construction project, and the like. Preferably, in the embodiment of the present disclosure, the drawing is a building plan view, which is used to represent the plan form, size, room arrangement, building population, hall and stair arrangement of the building, and indicates the positions, thicknesses, and materials used of the walls and columns, and the types and positions of the doors and windows.

The target area may be one or more areas directly selected by the user in the building plan, or may be an area obtained by the user through frame selection in the building plan by using a mouse or the like as needed (the area may be a part or all of an area in the building plan, or may be multiple areas in the building plan), which is not limited in this embodiment of the disclosure. Specific types of target areas may include, but are not limited to, shops, escalator areas, and public areas (e.g., toilets, stairwells, fire aisles, etc.). Further, specific types of shops may include, but are not limited to, catering type shops, entertainment type shops, apparel type shops, shopping type shops, service type shops, child type shops, and blank shops.

The target area identification may be the geographic location of the target area (e.g., a seat-1F-008, C2F03, etc.) or the name of the target area (e.g., nike exclusive shop, seafloor fishing, etc.), which is not limited by the embodiments of the present disclosure. Preferably, in the embodiment of the present disclosure, the target area is identified as the geographical location where the target area is located. For example, the unique identifier of a catering shop can be 'seat B-6F-018', the unique identifier of an entertainment shop can be 'seat B-8F-005', the unique identifier of a clothing shop can be 'seat B-3F-010', the unique identifier of a children shop can be 'seat B-5F-022', and the unique identifier of an empty shop can be 'seat B-2F-007'.

The model is a formal expression mode obtained by abstracting a certain actual problem or objective object and rule, and generally comprises three parts, namely an object, a variable and a relation. The models may include, but are not limited to, mathematical models, program models, logical models, structural models, method models, analytical models, management models, data models, system models, and the like. In the embodiment of the present disclosure, the model may be a Building Information Model (BIM), which is an engineering data model based on three-dimensional digital technology and integrating various related information of the construction engineering project, and the real information of the building is simulated through digital information simulation. The model data refers to model data created by various building information modeling techniques.

The model data may include Revit model data, which is file data used by Revit software, or CAD model data, which is file data used by AutoCAD software. Here, Revit is a piece of three-dimensional BIM design software (main file format is rvt, rfa, or rte, etc.) that can be used to convert building standards into data storage. It should be noted that the model data is not limited to Revit model data or CAD model data as described above, but may include file data of other engineering drawing-type software (e.g., CATIA, Pro/engine, SolidWorks, etc.).

The adjusted model data refers to model data that is adjusted or improved from pre-configured model data so that a lightweight engine, which will be described later, can recognize and load. Further, the adjusted model data may include a resource data set and a component data set. Here, the resource data set refers to a set of data of an editable area (e.g., an available area of a shop) in the building plan, and includes, but is not limited to, an area identifier, an area name, an area, an area type, and outline data of an area corresponding to the area identifier; further, the contour data may include, but is not limited to, point data, edge data, and region data. A component data set refers to a set of data for a non-editable area (e.g., a wall, a structural column, a floor, a door, a window, a stair, etc.) in a building plan, including, but not limited to, component identification, property data, and geometric data for a component. Here, the member means each element constituting an area (building), and for example, the building may be a window structure of a shop, and the member may be a window frame, a glass, or the like of the window. The component identifier is used to distinguish different components. The attribute data may include the size, area, material, etc. of the component. The geometry data may include, but is not limited to, coordinates of the part and part types, which may include, but are not limited to, points (points), lines (LineString), faces (Polygon), multi-points (multipoints), multi-lines (MultiLineString), multi-faces (MultiPolygon), and geometry collections (geometriceycallection).

Plug-in (Plug-in) is a program written in an application program interface conforming to a certain specification, and can only run under a system platform specified by the program (possibly supporting multiple platforms simultaneously), and can not run independently from a specified platform. The first plug-in can be a CAD plug-in, which is a plug-in for secondary development based on AutoCAD and is used for reversely converting a CAD graph edited in a webpage into a graph in an AutoCAD format. Here, the secondary development means that customized modification is performed on existing software to extend functions, that is, to achieve desired functions; secondary development does not typically change the kernel of the original system.

An Application Programming Interface (API), also called API, is a convention for linking different components of a software system. The API is actually a function set, and from the perspective of a user, the API appears as a series of API functions which can be used by the user to develop network application programs; from the network perspective, the API provides a set of methods for the user, the user can use the set of methods to send service requests, information and data to the application layer, and the layers in the network respond in sequence to finally complete the network data transmission. In the disclosed embodiment, the CAD plug-in traverses the resource data set and invokes the corresponding API to draw the outline of the target region based on the type data of the component. For example, when the type data of the component is "Point", the CAD plug-in calls an API for drawing a Point; when the type data of the component is "Polygon", the CAD plug-in calls the API of the drawing surface.

According to the technical scheme provided by the embodiment of the disclosure, a drawing generation instruction is received, wherein the drawing generation instruction is used for indicating the generation of the drawing of a target area and comprises a target area identifier of the target area; determining whether an area identifier which is the same as the target area identifier exists in the adjusted model data or not, wherein the adjusted model data comprises a resource data set and a member data set, the resource data set comprises the area identifier and outline data of an area corresponding to the area identifier, and the member data set comprises type data of a member; under the condition that the region identification identical to the target region identification exists in the adjusted model data, based on the type data of the component, the corresponding application program interface is called by using the first plug-in, and the drawing of the target region is generated based on the contour data of the region, so that the standardization and the generalization of the drawing can be realized, the drawing efficiency is improved, a large amount of manpower and time cost are saved, the error rate is reduced, and the drawing manufacturing process and the engineering cooperation period are shortened.

In some embodiments, the drawing generation method further includes: receiving a drawing downloading instruction, wherein the drawing downloading instruction is used for indicating the drawing of a downloading target area; and deriving a drawing at least comprising the target area as a contract drawing based on the drawing downloading instruction, wherein the format of the contract drawing comprises any one of DWG format, PDF format, PNG format and JPG format.

Specifically, after receiving a drawing download instruction for instructing downloading of a drawing of a target area, the server derives the drawing at least including the target area based on the drawing download instruction, and takes the derived drawing as a contract drawing.

The contract drawing is also called as 'one user one picture', which is a plan view for explaining the basic layout of the house or the shop within the property range in the commercial room or shop buying and selling contract, and is a drawing basis for the condition of handing over the house within the agreed property range of the buyer and seller as an accessory of the selling contract, and is a file with legal effect committed to the client. The contract drawing may only include the drawing of the target area, may also include the target area and the building plan, or may also include the target area, the building plan and remarks or explanations, which are not limited by the embodiment of the disclosure. Further, the format of the contract figures may include any one of a DWG format, a PDF format, a PNG format, and a JPG format.

It should be noted that, if the contract figure to be exported is in a DWG format, the drawing can be directly saved in the DWG format; if the contract drawings needing to be exported are in other formats, the drawings need to be saved into the DWG format, and then virtual printing is called to save the files into other formats or directly print the drawings.

According to the technical scheme provided by the embodiment of the disclosure, drawings in different formats in any area can be generated by one key, so that personalized requirements of different users are met, and user experience is improved.

In some embodiments, the drawing generation instruction further includes project information and custom information, and the drawing generation method further includes: displaying a drawing of a target area in a first area of a contract drawing; displaying a building plan corresponding to the adjusted model data in a second area of the contract drawing; acquiring project information, and displaying the project information in a third area of the contract drawing; and acquiring the custom information, and displaying the custom information in a fourth area of the contract drawing.

Specifically, the drawing generation instruction may further include project information and custom information. Here, the project information refers to various information related to project implementation, such as reports, data, plans, schedules, technical documents, meetings, and the like; the custom information refers to special information corresponding to different items, namely, personalized information which needs to be additionally entered. In the embodiment of the present disclosure, the project information may be name information of a building to which the target area belongs, for example, beijing changchun. The custom information may be notes or descriptions about the project or contract figures, for example, description: the figure is only an illustration, and the house specific information is subject to the lease contract and the actual delivery status.

The contract figures may include one, two, or more regions. When the contract drawing includes a region, a drawing of the target region (i.e., a plan view of the target region) may be displayed in the region; when the contract drawing includes two areas (i.e., a first area and a second area), a drawing of a target area may be displayed in the first area, and a building plan (i.e., a plan of all shops on the floor where the target area is located) may be displayed in the second area; when the contract figure includes four regions (i.e., a first region, a second region, a third region, and a fourth region), a plan view of the target region may be displayed in the first region, a plan view of all shops on the floor where the target region is located may be displayed in the second region, project information may be displayed in the third region, and custom information may be displayed in the fourth region.

Further, in order to avoid the contract drawings from being stolen and tampered, watermarks can be added to the contract drawings and relevant watermark attributes can be set; the contract figure may also be encrypted, which is not limited by the embodiments of the present disclosure. Here, the watermark may include at least one of a text watermark and a picture watermark, and the watermark attribute may include at least one of a font, a text size, a watermark size, and an angle. The encryption algorithm may include, but is not limited to, MD5, DES, 3DES, IDEA, RSA, DSA, AES, RC2, RC4, and the like.

According to the technical scheme provided by the embodiment of the disclosure, the contract drawings can be prevented from being embezzled and tampered by adding the watermark to the contract drawings or encrypting the contract drawings, so that the safety, confidentiality and tamper resistance of the contract drawings are improved.

In some embodiments, the drawing generation method further includes: obtaining pre-configured model data, and converting the pre-configured model data into data which can be identified by a lightweight engine by using a second plug-in unit based on different data types; storing data which can be identified by a lightweight engine into GeoJSON format data, wherein the GeoJSON format data comprises attribute data and geometric data, and the attribute data comprises a plurality of region identifications of a plurality of regions; separating attribute data and geometric data of the GeoJSON format data by using a lightweight engine to obtain adjusted model data, wherein a resource data set in the adjusted model data comprises a plurality of region identifications of a plurality of regions; and displaying the building plan corresponding to the adjusted model data by using a webpage so as to carry out online editing operation on the building plan.

Specifically, after acquiring preconfigured model data, the server converts the preconfigured model data into data recognizable by a lightweight engine by using a second plug-in based on different data types, and stores the data as GeoJSON format data including attribute data and geometric data, wherein the attribute data includes a plurality of region identifiers of a plurality of regions; further, the server separates attribute data and geometric data of the GeoJSON format data by using a lightweight engine to obtain adjusted model data, wherein a resource data set in the adjusted model data comprises a plurality of region identifications of a plurality of regions; and displaying the building plan corresponding to the adjusted model data by using a webpage so as to carry out online editing operation on the building plan.

Here, the preconfigured model may be a BIM (native) model, i.e. a forward design model of BIM, e.g. a Revit model. The second plug-in may be a Revit plug-in or a CAD plug-in. For different data types, a different second plug-in may be utilized to effect the conversion from the preconfigured model data to the data recognizable by the lightweight engine. For example, when the preconfigured model data is Revit model data, the Revit model data can be converted into data recognizable by the lightweight engine based on the family type in Revit by using a Revit plug-in; when the pre-configured model data is CAD model data, the CAD model data can be converted into data recognizable by the lightweight engine using a CAD plug-in. It should be noted that the Revit plug-in and the CAD plug-in are both secondary development plug-ins.

And the lightweight engine is used for carrying out lightweight conversion on the BIM model, and loading and using the lightweight model. The light weight conversion is to convert the BIM into primitive data and model structured data through a light weight engine, wherein the primitive data is stored in the form of an original file; the model structured data is saved in a corresponding relational database in the form of data records so as to facilitate the retrieval and utilization of the data at a later time. The lightweight model is loaded and used by displaying the lightweight BIM in a webpage by using a WebGL technology, and comprises a BIM control function, a model member attribute customization function, a labeling and displaying function based on the BIM model and the like.

WebGL (Web Graphics library) is a three-dimensional (3 Dimensions, 3D) drawing protocol, the drawing technical standard allows JavaScript and OpenGL ES 2.0 to be combined together, and by adding one JavaScript binding of OpenGL ES 2.0, WebGL can provide hardware 3D accelerated rendering for HTML5Canvas, so that a Web developer can not only more smoothly show 3D scenes and models in a browser by means of a system display card, but also can create complex navigation and data visualization. Therefore, the WebGL technical standard avoids the trouble of developing a webpage-dedicated rendering plug-in, can be used for creating a website page with a complex 3D structure, and can even be used for designing a 3D webpage game and the like.

GeoJSON is a format for coding various geographic data structures, and is a geospatial information data exchange format based on Javascript object representation. The GeoJSON object may represent a geometry, a feature, or a set of features. GeoJSON supports the component types described above: point, line, face, multipoint, multiline, multifaceted and geometric collections. In an embodiment of the present disclosure, the GeoJSON format data may include attribute data and geometry data. Further, the lightweight engine is used for separating attribute data and geometric data of the GeoJSON format data to obtain adjusted model data.

A Web Page, also called a Web Page (Web Page), is a basic element constituting a website, and is a platform for carrying various website applications. The web page is to be read by a web browser. In the embodiment of the disclosure, the adjusted model data is loaded by using a web browser to display the building plan corresponding to the adjusted model data by using a page, so as to facilitate online editing operation on the building plan. Here, the editing operation may include one or more of an edit node operation, a tile splitting operation, a tile deleting operation, a pan rotating operation, a chamfering operation, a straight line arc turning operation.

According to the technical scheme provided by the embodiment of the disclosure, through improvement on Revit or AutoCAD, the preset model data can be converted into the adjusted model data by using the lightweight engine, so that the building plan corresponding to the adjusted model data can be loaded and displayed on the webpage, and lightweight display is realized.

In some embodiments, determining whether the region identifier identical to the target region identifier exists in the adjusted model data comprises: the target area identifier is compared with each of the plurality of area identifiers to determine whether the area identifier identical to the target area identifier exists in the plurality of area identifiers.

Specifically, the server traverses the plurality of area identifiers one by one to determine whether an area identifier identical to the target area identifier exists in the plurality of area identifiers; further, in the case that it is determined that there is an area identification identical to the target area identification among the plurality of area identifications, the server performs color filling and/or slashing processing on the target area in the building plan.

According to the technical scheme provided by the embodiment of the disclosure, the position of the target area in the building plan can be highlighted by carrying out color filling and/or oblique line processing on the target area in the building plan, so that the visual requirement of a user is met, and the user experience is improved.

In some embodiments, generating a drawing of the target area based on the contour data of the area includes: generating a contour line of the region based on the coordinates and the identification of the point in the contour data of the region and the start position and the end position of the edge, and generating a drawing of the target region based on the contour line of the region.

In particular, the contour data may include, but is not limited to, coordinates and identification of points, identification of edges, type, thickness, alignment, start and end positions, identification of regions and points, and the like. The server may generate a contour line by an algorithm of extracting the contour based on the coordinates of the points and/or the start position and the end position of the edge, and generate a drawing of the target area based on the contour line. Here, the algorithm for extracting the contour may include, but is not limited to, a contour extraction algorithm, a boundary tracking algorithm, a region growing algorithm, and a region splitting and merging algorithm.

The above drawing generation method is described in detail below by taking a market plan of a albino sky street shopping center in beijing as an example.

Firstly, creating Revit model data based on a preconfigured Revit model, and converting the Revit model data into data which can be identified by a lightweight engine by using a plug-in developed secondarily by Revit based on a family type in Revit; further, storing the converted data as GeoJSON format data, wherein the code of the GeoJSON format data is as follows:

{

"properties": {

"id" B-1F-014 ",

"name": monopoly store ",

"type": "CBD_MONOPOLY_SHOP",

"area": 82.54900158394956,

"revitId": 123456

},

"geometry": {

"coordinates": [

[0, 1],

[1, 1],

[1, 0],

[0, 0]

]

}

}。

as can be seen from the above code, the GeoJSON format data includes two parts of content, attribute data (properties) including an identification of a region (B-1F-014), a name (exclusive SHOP), a type (CBD _ monoply _ SHOP), an area (82.54900158394956), and a Revit identification (123456), and geometric data (geometry) including coordinates of points of the region ([ 0, 1], [1, 0], and [0, 0 ]).

It should be noted that, only data of one region is shown here as an example, and in practical applications, data of multiple regions may be included in the GeoJSON format data.

Next, the attribute data and the geometric data are separated from each other by using a lightweight engine, so as to obtain adjusted model data (levels), wherein the code of the adjusted model data is as follows:

{

"levels": [

{

"height": 0,

As can be seen from the above codes, the adjusted model data mainly includes two parts of contents of resource data sets (areas) and component data sets (entities). The resource data set includes an identification of the region (B lot-1F-014), an area (82.54900158394956), a brand (D8D), a name (exclusive store), a type (CBD _ MONOPOLY _ SHOP), vertices (vertices), edges (edges), and a region (region). The component data set comprises attribute data (properties) comprising an area (36.657025090908355), a name (STAIRS/ramps) and a type (CBD _ STAIRS) of the component and geometry data (geometry) comprising coordinates ([ 0, 2], [2, 0], [4, 0] and [4, 2 ]) and a type (Polygon) of the component.

It should be noted that, only data of one component is shown here as an example, and in practical applications, data of a plurality of components may be included in the adjusted model data.

Next, the adjusted model data is loaded by using a browser, so as to display a shopping mall plan corresponding to the adjusted model data on a page, as shown in fig. 3 (a). When a user selects any target area (such as a gray area in fig. 3 (a)) in a market plan to generate a contract drawing, the server encapsulates the adjusted model data (levels), project information (project), target area list (areelist) to be exported and custom information into new JSON-format data, and sends the new JSON-format data to the plug-in for AutoCAD secondary development, wherein specific codes of the new JSON-format data are as follows:

{

"levels": [

{

……

}

],

project, Beijing Changchun (a Chinese character 'Tianjie',

"areaList": [

"B shop-1F-014"

],

"ExtraStr": [

"shop number: shop B-1F-014 ",

]

}。

From the codes, the new JSON format data comprises project information (Beijing Adriana albizzia sky street), a target area list to be exported (shop number: shop-1F-014 and description: the figure is only schematic, and the house specific information is subject to the leasing contract and the actual delivery status).

Note that, since the code of the adjusted model data (levels) is not changed in the new JSON format data, specific data thereof is omitted.

Further, when new JSON format data is received, the plug-in of the AutoCAD secondary development carries out serialization operation on the new JSON format data, and the identifiers of all the regions in the resource data set are traversed one by one on the basis of a target region list (library-1F-014) to be exported, so that whether the identifiers identical to the target region list to be exported exist in the resource data set or not is determined. In the case where it is determined that the same identification as the target region list to be derived exists in the resource data set, the vertex coordinates of each vertex are found based on the identification of the point (points) in the region (region) (e.g., 9d3328db-687a-472f-9419-f610c09cec93, etc.), and the built-in API of the drawing surface in AutoCAD is called based on the type (Polygon) in the component data set (entities) to draw the outline of the target region, i.e., the plan view of the target region, as shown in fig. 3 (b).

Finally, a drawing including the target area is generated as a contract drawing, which is in the DWG format, as shown in fig. 3 (c). In FIG. 3(c), the view in the first area 301 is a plan view of the target area, the view in the second area 302 is a plan view of the mall, and the plan view of the target area is also an enlarged view of the gray area in the plan view of the mall; the content in the third area 303 is item information, and the content in the fourth area 304 is custom information.

It should be noted that, in order to avoid the theft and tampering of the contract figure, a watermark may be added to the contract figure and a related watermark attribute may be set, as shown in fig. 3 (d); the contract figures may also be encrypted.
