At the same time, CopyCAD also provides the shape editing function of the triangle model, which can generate standard voxel triangle models such as cylinder, cone, cuboid, sphere, etc. It can perform Boolean operation and clipping on the triangle model, and imitate the triangle model, and also add Text, decorative patterns, trademarks, and wrap functions of the triangle model, so that you can directly model and edit the model without having to transfer CAD software to build the surface, and then you can output STL files in binary or ASCII format for rapid prototyping. Or CNC machining.
In CopyCAD, you can divide by different colors according to the surface shape of the triangle model, divide the area, divide the model into several areas, and extract the contour curve to facilitate the generation of the surface.
3. How to construct the curve
As a way to construct a surface in reverse engineering, a structural curve can be created for the generation of a reverse surface, or it can be directly exported to a CAD system for forward modeling. Therefore, a smooth curve is also important for building a surface. CopyCAD provides a way to generate a variety of construction curves. The construction curve can automatically generate a construction curve directly from the boundary, horizontal line or section line of the triangular model. It can also be generated directly on the point cloud and on the triangle model, or generated by scan lines.
In the reverse design, the smoothness adjustment of the curve is very important, it will directly affect the quality of the generated surface. CopyCAD provides powerful curve fitting and smoothing functions, which can be used for smooth fitting or precise fitting, arc fitting, etc. according to model and design requirements. It can also be automatically generated according to the shape of the triangular model, and at the same time control whether it is tangent to the existing curve and surface, so as to construct the surface flexibly.
