How to convert Rhino
to cadwork?

Rhinoceros (typically abbreviated Rhino, or Rhino3D) is a commercial 3D computer graphics and computer-aided design (CAD) application software. Rhinoceros geometry is based on the NURBS mathematical model, which focuses on producing mathematically precise representation of curves and freeform surfaces in computer graphics (as opposed to polygon mesh-based applications).

Rhinoceros is used in processes of computer-aided design (CAD), computer-aided manufacturing (CAM), rapid prototyping, 3D printing and reverse engineering in industries including architecture, industrial design (e.g. automotive design, watercraft design), product design (e.g. jewelry design) as well as for multimedia and graphic design.

The Rhinoceros file format (.3DM) is useful for the exchange of NURBS geometry. The Rhino developers started the openNURBS Initiative to provide computer graphics software developers the tools to accurately transfer 3-D geometry between applications. An open-source toolkit, openNURBS includes the 3DM file format specification, documentation, C++ source code libraries and .NET 2.0 assemblies to read and write the file format, on supported platforms (Windows, Windows x64, Mac, and Linux).

cadwork is a CAD software, developed by the CSEM. It allows users to draw, to design, or to manufacture. Originally, cadwork was created for the watch industry, but now it is mostly used by the architecture, engineering and construction market, that is civil engineering, carpentry, topographic, road building, architecture, armed concrete, glue laminated timber, stairs.

cadwork offers special modules to provide solutions for different tasks. The modules are fully-fledged components, related to each area of activity and they can be arranged to represent an entity. Thus, they can be exchanged against other modules, or complete an already existing CAD / CAM solution. The existing modules are the following: 2D-Layouts and details, 3D-Modeling, cadwork Viewer, 3D-Cabinet, Roof, Element, List, Piece by piece shop drawing, CNC machines, Staircases, Variant-parametric, Glulam.
