Method for two-dimensional and three-dimensional mixing in modeling software

Abstract

The invention belongs to the field of information processing of buildings, and particularly relates to a method for two-dimensional and three-dimensional mixing in modeling software. The method comprises the following steps of 1, establishing drawing spaces; 2, establishing types of members and models, and determining a method for different drawing spaces to generate display data; 3, according to the types of members and models, establishing different sizes of members, and generating the display data; 4, obtaining the display data which meets the preset condition, and establishing a mapping table between the display data and the drawing space of each member; 5, switching the drawing spaces, and obtaining the display data of each member in the corresponding drawing space according to the mapping table between the display data and the drawing space of each member; according to the display data of each member in the corresponding drawing space, positioning and combining, and forming a building model. The method has the advantages that the two-dimensional drawing can be converted to generate drawings meeting the national and industry standards according to the actual requirements, and the generating efficiency of the two-dimensional drawings is improved.

Description

technical field [0001] The invention belongs to the field of building information processing, in particular to a method for mixing two-dimensional and three-dimensional in modeling software. Background technique [0002] With the rapid development of urban construction, the demand for building products with high quality, short construction period and low cost is increasing, which also puts forward higher requirements for architectural design. Therefore, modeling software that can restore the real information of buildings through three-dimensional digital information and use high-precision product models to control the construction process was born. [0003] Architectural design is a huge project. A complete architectural modeling requires the construction and organization of various design elements, which cover the planning location, external shape, internal layout, internal and external decoration, detailed structure, fixed facilities and construction requirements of the bu...

Problems solved by technology

Take the stairs as an example, such as figure 2 As shown, a is the three-dimensional model of the stairs (the direction of the arrow is viewed from top to bottom), b is the data projection of the top view, and c is the top view required by the design specification Figure II dimensional representation (the direction of the arrow is upward), obviously its front view graphics cannot be obtained by simply cutting the 3D model in the direction of the front view

In addition, for some models with a lot of design elements, especially architectural models, due to the huge volume and complex structure of the building, the projection and section efficiency is extremely low, and the memory of the budget process can easily reach a peak, resulting in poor generation of 2D views. success
