II. Free CAD software for experienced CAD users
This is not your first try in 3D modeling, but you don’t want to invest in an expensive professional CAD software? These free CAD software for experienced CAD users, inspired by the best professionals ones are perfectly suited for your needs.
Due to its drag and drop approach to create your model, 3D Crafter is a pretty intuitive program. The software is adapted to create complex models, and you can even upgrade it with additional features for game development or to render photo-realistic images. Also, the tutorials included in the software are really useful to help you within the first steps of your creation.
Files: if you want to export as anything other than POVRay or Renderman, you have to upgrade to either 3DCrafter Plus ($35) or 3DCrafter Pro ($70).
Art of Illusion is the most used software within the RepRap community. The software is animation-oriented but is still really adapted when one is looking for a software that is both mixing modeling and rendering. Also, it has a good subdivision surface feature.
Files Format: wavefront .OBJ, VRML or Povray
Blender is well known for its steep learning curve, however, it is very powerful. Given that this software has a mesh-based direct modeling and not a parametric one, it is more relevant for an artistic use. Nevertheless with features as rendering sculpting and fast modeling, it is still very adapted to create your 3D model for 3D printing.
