Description
Technical field
The invention belongs to architecture information process field, particularly relate to a kind of device setting up three-dimensional building information model fast.
Background technology
Along with the fast development of building industry, the building products demand that quality is high, the duration is short, cost is low is increasing, and this also has higher requirement to architectural design.BIM, by three dimensional digital simulation simulant building thing, utilizes high accuracy three-dimensional model and Construction procedures to control, can significantly improve design efficiency and model quality.But in traditional building industry, due to historical reasons and technical limitation, two-dimensional design environment is generally applied in architectural design, period creates the two-dimensional design drawing of flood tide, and two-dimentional drawing mainly lacks the drawing of architecture information.As the BIM of three-dimensional digital model, need the regular hour at the universal of technology, therefore, two-dimentional drawing being converted into three-dimensional model just becomes the fast route that is set up BIM.
But, BIM is usually very complicated, and do not only have the simple geological information of X-Y scheme paper, it not only relates to the multiple Specialty Designs such as building, electromechanics, HVAC, every class designs a model and also has thousands of design element, wherein also relates to the non-geometry information that material, illumination etc. are complicated.If manually two-dimentional drawing is converted into BIM, then two classes that must relate to geological information and non-geometry information are changed, and work will be very loaded down with trivial details, and the cycle also can be very long.
At present, existing two-dimentional drawing is converted into the technical scheme of three-dimensional model, is mainly divided into two classes:
1) in two-dimensional stage, two-dimentional drawing is converted to three-dimensional model, but this model is the three dimensional stress of two dimension view, also can carries out the three-dimensional editor of a part.The program has following technological deficiency: the function that can not provide complete editor's three-dimensional model, and the modelling effect of generation can not meet the demands completely, cause the artificial constructed meticulous three-dimensional model of needs, and the interdependence between three-dimensional structure also cannot ensure; Program two dimension can not meet the requirement of self-defined building element in process of architecture design; Due to the restriction of the three-dimensional editting function of two-dimensional stage, the program generally has the fixing product library closed, and adopts fixing three-dimensional model, can not meet requirement flexible and changeable in architectural design.
2) utilize olive mountain software to extract architecture information in the positive two dimensional model in sky, generate intermediate file, utilize intermediate file and two dimensional model, in Revit software, establish three-dimensional model.The program does not realize complete techniqueflow, and it depends on the process that other software simulating extract architecture information from two-dimensional signal, is only limited to the conversion of a kind of two-dimentional drawing to three-dimensional modeling, can not applies, greatly limit the use of user.And the program is by the restriction of extracting method, can not extract more Multiple Shape, only support the reduction of the component of solid shape, reduction degree is not enough.
Summary of the invention
The object of the invention is to for the problems referred to above, a kind of device setting up three-dimensional building information model is fast provided, two-dimentional drawing is resolved, make the component in the pel of two-dimentional drawing and three-dimensional building model set up one-to-one relationship, then by geometry parsing, two-dimentional drawing is converted into three-dimensional information model.
The embodiment provides a kind of device setting up three-dimensional building information model fast, comprise
Data obtaining module, for obtaining geometry and the non-geometry information of two-dimensional primitive, and classifying to the architecture information of this two-dimensional primitive, obtaining the architecture information kind of this two-dimensional primitive;
