Abstract

The present invention relates to the BIM parametric modeling method of specifically sled sled racing track；It is characterized in that: including with Grasshopper software parameterization batch in-depth fixture drawings；According to the fixture drawings after in-depth, with Rhino software parameter metaplasia at accurately fixture 3D Modifying model fixture；Fixture model automatically extracts the space coordinate and mileage coordinate of all fixtures, cooperates the correction work of fixture installment work and 3D surveying party in space orientation to absolute coordinate position；Automatic segmentation cutting, number work and the processing drawing for exporting pipe cutting of automatic end conduit overall length.This method completes the in-depth of drawing by Rhino software parameterization, reduces modeling degree of participation by hand, improves the accuracy of model and data, while can complete the strong and complicated work of logicality in batches, improves working efficiency, guarantee making smooth advances for project.

Description

The BIM parametric modeling method of sled sled racing track

Technical field

The present invention relates to the fields of building of complicated high-accuracy shaped component, specifically the BIM parametrization of sled sled racing track Modeling method.

Background technique

Design scheme precision ± the 5mm of sled sled racing track, this requires very BIM design work and site operation link Strictly, an effective scheme must be strictly formulated from being designed into construction, just can guarantee that the construction precision of project reaches and set Meter requires.Wherein, for how lifting clamp drawing precision and ensure the prefabricated work of fixture, extract 1490000 groups of space coordinates Ensure that fixture installation positioning is a technical problem.

Summary of the invention

The object of the present invention is to provide a kind of BIM of sled sled racing track that can satisfy above-mentioned requirements parametrizations to build Mould method.

In order to achieve the above object, the present invention is implemented as follows:

A kind of BIM parametric modeling method of sled sled racing track, including

Step 1 deepens fixture drawings with Grasshopper software parameterization batch, and fixture drawings is made to meet the high-precision of fixture The prefabricated work of laser integral cutting of degree；

Step 2, according to the fixture drawings after in-depth, with Rhino software parameter metaplasia at accurately fixture 3D model Stp or Obj formatted file and with 3D scan incision at the point cloud model of actual chuck compare, to control mismachining tolerance, process ring Section amendment fixture；

Step 3, fixture model in space orientation to absolute coordinate position, automatically extract the space coordinate XYZ of all fixtures with it is inner Journey coordinate SHL data cooperate the correction work of fixture installment work and 3D surveying party；

Step 4, using Grasshoppe program according to step 3 gained coordinate, the automatic segmentation cutting of automatic end conduit overall length is compiled Number work and export the processing drawing of pipe cutting.

This method completes the in-depth of drawing by Rhino software parameterization, reduces modeling degree of participation by hand, improves model And the accuracy of data, while the strong and complicated work of logicality can be completed in batches, BIM working efficiency is greatly improved, is mentioned in batches Control coordinate data is taken, construction precision is controlled, strong technical support is provided to project construction, guarantees making smooth advances for project.

Specific embodiment

The present invention is further illustrated below by way of specific embodiment.

A kind of BIM parametric modeling method of sled sled racing track, including

Step 1 deepens fixture drawings with Grasshopper software parameterization batch, and fixture drawings is made to meet the high-precision of fixture The prefabricated work of laser integral cutting of degree；

Step 2, according to the fixture drawings after in-depth, with Rhino software parameter metaplasia at accurately fixture 3D model Stp or Obj formatted file and with 3D scan incision at the point cloud model of actual chuck compare, to control mismachining tolerance, process ring Section amendment fixture；

Step 3, fixture model in space orientation to absolute coordinate position, automatically extract the space coordinate XYZ of all fixtures with it is inner Journey coordinate SHL data cooperate the correction work of fixture installment work and 3D surveying party；

Step 4, using Grasshoppe program according to step 3 gained coordinate, the automatic segmentation cutting of automatic end conduit overall length is compiled Number work and export the processing drawing of pipe cutting.

This method completes the in-depth of drawing by Rhino software parameterization, reduces modeling degree of participation by hand, improves model And the accuracy of data, while the strong and complicated work of logicality can be completed in batches, BIM working efficiency is greatly improved, is mentioned in batches Control coordinate data is taken, construction precision is controlled, strong technical support is provided to project construction, guarantees making smooth advances for project.
