Research on Entity Model Directly Layering Software Design Based on the Secondary Development of AutoCAD

Abstract:

FDM process of rapid prototyping systems at present which can only reads the STL format file, based on this format can be get the 2-d layer is composed of straight line segments connected polygon contour, makes the model layer of information that are geometric distortion, leading to surface accuracy is poorer; Produced based on STL model for layered geometric distortion problem, this paper put forward to directly layering of entity model, and through the ObjectARX which is the secondary development tools of AutoCAD realizes layer directly in the software, the layer of 2-d contour for smooth curve, so as to ensure accuracy, it will be played an important role in the practical application later.
