Description

A kind of BUILDINGS MODELS design method

Technical field

The invention belongs to architecture information technical field, and in particular to a kind of BUILDINGS MODELS design method.

Background technology

At present, BUILDINGS MODELS design is general is designed using two dimensional surface, exchanges less between each specialty, causes each specialty two dimension There is contradiction in planar design, influences construction speed, brings economic loss.With the popularization and application of BIM technology, in layout design rank The design contradiction that section is reduced between each specialty is possibly realized.

The content of the invention

The deficiency existed for above-mentioned prior art, the present invention provides a kind of BUILDINGS MODELS design method.

Technical scheme：

A kind of BUILDINGS MODELS design method, including：

Step 1：The two-dimentional drawing of Civil Specialities, reinforcing bar specialty, hot-water heating electricity specialty, fire-fighting specialty and ventilation specialty is drawn, The two-dimentional drawing is the two-dimentional drawing with size；

Step 2：According to each professional X-Y scheme paper size information, foundation can clearly reflect each complex node construction and two Each professional threedimensional model for tieing up detailed construction inside drawing is each professional 3D models；

Step 3：The point of impingement in collision detection, modification 3D models is carried out to single specialty 3D models；

Step 4：The collision detection between specialty 3D models two-by-two is carried out, the point of impingement in each professional 3D models is changed；

Step 5：The collision detection between all professional 3D models is carried out, distinguishes that the point of impingement is true and false, and change each professional 3D moulds The true point of impingement in type；

Distinguish that the true and false specific method of the point of impingement is：Reported according to the collision detection of generation and each professional 3D models, according to The secondary axle for checking whether collision vertex type is that pipe is through walls, is that the point of impingement is the false point of impingement, otherwise, is built according to point of impingement correspondence Line position, absolute altitude and actual size, distinguish that the point of impingement is true and false.

Step 6：The two-dimentional drawing of each specialty is improved according to amended each professional 3D models, BUILDINGS MODELS design is completed.

Beneficial effect：The present invention a kind of BUILDINGS MODELS design method compared with prior art, with following advantage：

By three-dimensional modeling, reflection design produced problem directly perceived carries out collision detection using BIM technology, finds out each special Collision problem between industry, and then design drawing is changed, improve the quality of design, it is to avoid the economic damage that drawing change tape comes Lose, effect is especially pronounced in the architectural design engineering more than complicated, professional intersection.

Brief description of the drawings

Fig. 1 is the BUILDINGS MODELS design method flow chart of one embodiment of the present invention；

Fig. 2 is the Civil Specialities 3D illustratons of model of one embodiment of the present invention；

Fig. 3 schemes for the collision detection report of one embodiment of the present invention.

Embodiment

One embodiment of the present invention is elaborated below in conjunction with the accompanying drawings.

As shown in figure 1, a kind of BUILDINGS MODELS design method of present embodiment, can by setting up three-dimensional using BIM technology Layout design is solved the problems, such as depending on changing model, drawing change phenomenon is effectively improved, is the drawing more than complicated, professional intersection Design provides a kind of facilitated method, comprises the following steps：

Step 1：Required according to owner, drafting Civil Specialities, reinforcing bar specialty, hot-water heating electricity specialty, fire-fighting are professional and logical respectively Wind specialty carries the two-dimentional drawing of size；

Step 2：According to each professional X-Y scheme paper size information, using BIM softwares, foundation can clearly reflect that each is complicated Each professional threedimensional model of detailed construction is each professional 3D models inside joint structure and two-dimentional drawing；In present embodiment, soil Build professional 3D illustratons of model as shown in Figure 2.

Step 3：Collision detection is carried out to single specialty 3D models using BIM softwares, and changes the point of impingement in 3D models；

Step 4：Two professional 3D models are imported together using BIM softwares, touching between specialty 3D models two-by-two is carried out Inspection is hit, is reported according to the collision detection of generation, the point of impingement in each professional 3D models is changed；

As shown in figure 3, the collision detection is reported place contradictory between professional 3D models in the form of word forms Reflect, there is sectional drawing, positional information and the title for colliding component of the point of impingement in word forms.

Step 5：Each professional 3D models are imported into together using BIM softwares, the collision between all professional 3D models is carried out Check, according to the report of the collision detection of generation and each professional 3D models, distinguish whether the point of impingement is the true point of impingement, and change each The true point of impingement in professional 3D models；

The point of impingement in collision detection report is not all objective reality, and some are because BIM softwares can not realize intelligence False judgment is distinguished and makes and to obtain, the false point of impingement of formation, the true and false needs of the point of impingement are manually recognized one by one.

In present embodiment, when collision vertex type is manages through walls, it is believed that the point of impingement is the false point of impingement；If the point of impingement is Because collision scantling, position are caused by there are errors in computation, it is believed that the point of impingement is the true point of impingement, correspondence 3D models need to be changed.

Claims

1. a kind of BUILDINGS MODELS design method, it is characterised in that comprise the following steps：

Step 1：Draw the two-dimentional drawing of Civil Specialities, reinforcing bar specialty, hot-water heating electricity specialty, fire-fighting specialty and ventilation specialty；

Step 2：Each professional 3D models are set up according to the two-dimentional drawing of each specialty；

Step 5：The collision detection between all professional 3D models is carried out, distinguishes that the point of impingement is true and false, and change in each professional 3D models The true point of impingement；

2. BUILDINGS MODELS design method according to claim 1, it is characterised in that two-dimentional drawing is band in the step 1 There is the two-dimentional drawing of size；Step 2 specific method is：According to each professional X-Y scheme paper size information, foundation can be clear Reflect each professional 3D models of detailed construction inside each complex node construction and two-dimentional drawing.

3. BUILDINGS MODELS design method according to claim 1, it is characterised in that true and false specific of the discrimination point of impingement Method is：It is examined in whether collision vertex type is that pipe is through walls, is that the point of impingement is the false point of impingement, otherwise, according to point of impingement correspondence Axial location, absolute altitude and the actual size of structure, distinguish that the point of impingement is true and false.
