FreeCAD
Ok, first FreeCAD:
As they say themselves, it is still in the early stages of development. I (Conor) have searched for documentation, and apart from the getstarted [1] there are 2 nice articles from December (so version 0.9, which btw. is in Lucid already). The funny thing is that for some reason, both are in... Polish! I understand you have polish origins, so maybe you speak Polish. Otherwise just google translate. They give you examples and a better idea of what it is right now capable of. [2] [3]
So I propose the following: you try to reproduce the steps in the articles, so you get a feeling for it. But then regardless stick with Blender a bit longer, and try FreeCAD again when version 0.11 or 0.12 comes out.
OSE FreeCAD Documentation
I (Mark Norton) have created a very simply, introductory guide to FreeCAD. It only covers the very basics at this point, but we can expand on it as needed. - User:Mjn
This document covers the following topics:
- Views
- Workshops
- Sizing a Primitive Part
- Positioning a Part
- Making a Cut
- Combining Parts
- Rotating a Part
- Extrusion
