Conversion from Rhino3D to SLDASM is not supported yet :(

Rhinoceros (typically abbreviated Rhino, or Rhino3D) is a commercial 3D computer graphics and computer-aided design (CAD) application software developed by Robert McNeel & Associates. It is used in industries including architecture, industrial and product design, in multimedia and graphic design and runs on Microsoft Windows and OS X. Rhino uses Grasshopper, a visual scripting language add-on, developed by Robert McNeel & Associates.

Rhino is based on the NURBS mathematical model, so it focuses on producing precise representations of curves and freedom surfaces. It allows users to create, edit, analyse, and visualize NURBS curves, surfaces, solid bodies, point clouds and polymeshes.

SLDASM is a SOLIDWORKS Assembly File. It refers to a SOLIDWORKS 3D assembly, which consists of several SOLIDWORKS part files (SLDPRT). An assembly file itself may contain some children SLDASM files, as well as some SLDPRT part files.

SLDASM are proprietary files with closed specifications. Nevertheless, some APIs (like CAD Exchanger SDK) provide the facility to read and convert them to other formats.

Software applications like Autodesk Fusion 360, Okino PolyTrans, and AMADA SheetWorks can import and render SLDASM files created with SOLIDWORKS.
