Further, in the step (2), according to the pipeline extracted and completed in the step (1) and the system effectively connected with the node, the original system is converted, the current pipeline conversion function is adopted, the pipeline is converted into the identifiable pipeline system in the PingLeader system, the node which is possibly not successfully converted is corrected, the whole pipeline system is redefined and stored, and the newly-built pipeline system is redefined.
In the step (3), defining a newly-built pipeline system according to the pipeline text information when cad is loaded and the pipeline system which can be identified by the PinggLeader platform generated in the step (2); according to the key word arrangement of the characters, the character recognition mode is defined to facilitate the extraction of the characters; and giving information to each section of pipeline according to the extracted information, correcting and finally obtaining correct information of the pipe diameter and the pipe material of each section of pipeline through the LIST and pipe diameter marking updating function.
Defining the elevation of the pipeline system obtained in the last step, giving the elevation of the node by identifying and extracting elevation information of the node characters, and simultaneously connecting the pipeline elevation of the node in a linkage manner; or defining a node elevation and endowing the gradient of the whole pipeline, and determining the elevation of the whole pipeline system; carrying out model selection on the nodes in batches, determining the types of wells, and selecting and determining the types of the nodes one by one for individual special nodes; converting the whole system by using a two-dimensional to three-dimensional function, and rechecking by using three-dimensional roaming to generate a three-dimensional simulation; and finally converting the three-dimensional model into a BIM model by exporting data to a revit function.
The method has the following advantages:
one is to provide an efficient means. The process does not adopt three-dimensional modeling operation, but can build a two-dimensional model into a three-dimensional model, and through the functions of batch selection and identification and the like, the model can be conveniently and quickly built, so that the waste of manpower and material resources caused by re-die-turning or modeling is avoided.
Secondly, the Pinggleader platform is skillfully utilized to carry out deep excavation and utilization on functions in the Pinggleader platform, so that the two-dimensional model can be converted into a three-dimensional model, the BIM model can be obtained, meanwhile, the corresponding functions of the Pinggleader platform can be utilized to facilitate the modification and the perfection of the construction drawing in the drawing process, and the two-dimensional drawing is facilitated.
