Description

A method of generating BIM models

Technical field

The invention belongs to architectural design industries, the more particularly to information model of construction（BIM）Design field, tool Body refers to the BIM Computer Aided Designs of building relevant industries, including but not limited to concrete structure BIM designs, concreting The BIM of template is designed, the BIM designs and building curtain wall system BIM designs of building scaffold system..

Background technology

Building Information Model (BIM) is the new tool of architecture, engineering science and civil engineering, compared to traditional CAD bis- Drawing Design mode is tieed up, BIM designs can reduce all kinds of mistakes caused by design team member in large quantities at design initial stage, simultaneously Also the follow-up mistake manufactured manufacturer and made can be reduced.It can thus reduce and build the required time, while also contribute to reduce The cost of engineering.Currently, in the reinforced concrete structure construction applications of building, BIM designing techniques have had been widely used, Also the more and more extensive every field for penetrating into building simultaneously.

On more complicated building element, if building concrete is poured with stencil design, connection system for guide rail is designed and is built In terms of building Curtain Wall Design, although at present there are also the trial of BIM designs, practical application is also fewer, a main cause It is that, for complicated building element, modeling is difficult, and the cost of BIM Modeling and Designs is very high, inefficiency, it is difficult to meet engineering It needs.

Conventional BIM design methods at present are to use first to establish building element model race library, then according to project It is required that get well and be put into design position by various building element model foundations, for conventional building beam column model, due to structure compared with To be simple, the method efficiency is fine, but for complicated building element, establishes that component race library is extremely difficult, and positioning is placed into sets Meter position is also usually not easy to accomplish, and significantly limits application of the BIM designs in these fields.

Invention content

In order to improve the efficiency of BIM modellings, design accuracy is promoted, the present invention provides one kind being based on building element Binding face or center line are aided with element type information and quickly generate construction part information model（BIM）Method, feature is as follows.

1. based on three-dimensional building plans model（Bai Mo）Or in-depth figure is designed, building plans model or in-depth is flat Face figure is imported into three-dimensional software, and secondary development, in particular to sketch great master are carried out in 3 d modeling software（Sketchup）, Revit, Solidwork, 3Dmax, AutoCAD etc. but not limited to this 3 d modeling software.

2. method is embodied as the first progress unwrapping wire planning on building plans model, by building element in building plans Image Segmentation Methods Based on Features line in model is drawn, this process can be hand drawn, can also be computer according to certain algorithm plan It is slightly automatic to draw.

3. the face of buildings model is split by the line after planning, become various building elements（Such as aluminum alloy pattern plate, curtain wall member Deng）Binding face or eigencenter line（Such as scaffold rod piece）, then these faces or line are enclosed into type information, information can be By applying material, the modes such as judgement carry out the specified or spatial positional information according to line face of message box automatically, last computer root Corresponding building element model is generated according to binding face or center line and type information.

4. the model generated is each an independent threedimensional model group or component, has necessary letter on model Breath, such as title, number, the model of material etc., completion is a kind of Building Information Model（BIM）Spelling can be derived automatically from by computer Dress figure, production figure and the bill of materials.

Present invention advantage compared with prior art：

(1) this method improves the accuracy of the efficiency and design of BIM model modelings design.

Specific implementation mode

The preferred implementation method of this method is：

（1）Using sketch great master（Sketchup）As three dimensional design platform, the three-dimensional plan model of building is imported into In Sketchup;

（2）Secondary development is carried out using Ruby in Sketchup, realizes that plotted line is drawn automatically according to layout strategy, and carry out The functions such as artificial inspection and modification;

（3）It is realized by face, by color face or by functions such as center line generation building element threedimensional models, is generated by secondary development Threedimensional model on have information, be a kind of information model（BIM）;

（4）The editting function of component model is realized by secondary development, is realized and is gone out construction diagrams automatically, the work(such as production figure and the bill of materials Energy.
