Preparation method of building terrain model and hot melt cutting device used therefor

Abstract

The invention relates to the field of fabrication of architectural models, and discloses an architectural terrain model preparation method. The architectural terrain model preparation method includesfollowing steps: simplifying a terrain elevation drawing, generating a three-dimensional model, generating vertical sections through sectioning, extracting the vertical sections one by one to performlofting on a sheet material, forming section plates, cutting a PVC (polyvinyl chloride) foam board in the thickness direction to form a plurality of to-be-clamped foam boards, respectively configuringthe plurality of to-be-clamped foam boards with the section plates, clamping one to-be-clamped foam boards by two adjacent section plates, and cutting off, portions, exposed out of the section plates, of the to-be-clamped foam boards to finally form an architectural terrain model. The invention further discloses a hot melting cutting device used by the architectural terrain model preparation method. The architectural terrain model preparation method and the hot melting cutting device used by the method avoid the problem that accuracy is low, caused by directly using the cross section of the elevation drawing in the lofting, cutting and positioning, and can fabricate the large-scale architectural terrain model, and furthermore fabrication is simple, cost is low, and significant economic benefits are obtained.

Description

technical field [0001] The invention relates to the field of making architectural models, in particular to a method for preparing an architectural terrain model and a hot-melt cutting device used therefor. Background technique [0002] With the continuous maturity of remote sensing technology, the data volume of remote sensing images and digital elevation is also increasing. Through the effective management and utilization of these data, the 3D display model becomes more and more efficient and realistic. At present, many companies have some architectural models, and many of these three-dimensional architectural terrain models are made by 3D printing technology. [0003] However, the existing 3D printing technology is difficult and expensive to print large solid models. If the cross-section of the elevation map is directly used for lofting, cutting and positioning, there will be inaccurate problems. Therefore, need badly a kind of production cost is low, and production met...
