First, open the rhinoceros model you want to export. If there are multiple models, you need to select the 3D objects to export in turn. After the selection is completed, click Select Dimension-Create 2D Picture, click Create, select the 2D graphic of the layer you need in the option box that appears, and click OK to open a cad image on the interface. Then click Export to the selected object in the file, and the selected curve can be exported to cad drawing. Finally, save the exported file as autocaddrawing(*dwg).

Rhino 3d NURBS (non-uniform rational b-spline) non-uniform rational b-spline curve. Is a powerful advanced modeling software; That is what three-dimensional experts say-rhinoceros software.

Rhino is a three-dimensional modeling software based on NURBS, which was launched by Robert McNeil Company in the United States on 1998. Its developers are basically the core coding members of the original alias (A/W company that developed MAYA).

AutoCAD (Autodesk Computer Aided Design) is an automatic computer aided design software first developed by Autodesk Company in 1982. Used in 2D drawing, detailed drawing, document design and basic 3D design, it has become a popular drawing tool in the world.

AutoCAD has a good user interface, and various operations can be performed through interactive menus or command lines. Its multi-document design environment allows non-computer professionals to learn to use it quickly. In the process of continuous practice, we can better master its various application and development skills, so as to continuously improve work efficiency. AutoCAD has wide adaptability and can run on microcomputers and workstations supported by various operating systems.
