Additionally, can both of these products handle component assembly and rendering? Also, I would like to know the differences between these two programs and IronCAD.

Thank you for asking.

The differences between CADian Pro and CADian 3D V7 lie in compatibility with software like Rhino, the ability to perform NURBS modeling, and features such as importing and editing OBJ files.

CADian 3D V7 appears to have many advantages, with high-quality rendering likely achieved using tools like KeyShot or other rendering software. IronCAD can be considered a specialized 3D design tool that emerged as an alternative to software like SolidWorks or Inventor.

Thank you.
