Hi all, I'm new here and also new to CAD software and I struggle to find my 'best' CAD software. FreeCAD looks fine for me at this point and there are lots of 'tutorial' videos in the net, but I still not get the workflow to work with the parts libary here from Openbuilds. Do you have some documentation showing how to place and connect the parts to a working build ? On a buzzword level, I think it uses contrains, but I failed to get even a V-Wheel with bearings, shim, screw, spacer etc. in the right order to use it for a further build. Is there anybody, who can point me to such a documentation or video showing for FreeCAD (or a different free Software for CAD beginners) to use the part libary for a 3D printer build ? For FreeCAD, my struggles starts already to know to run which operation in which workbench. The contrains button are almost greyed out.
