I've been trying for the last little while looking for an open source application for my Mac Mini that is running OSX 10.4.11 with the G4 processor that is in there. The application that I am looking for is something similar to like autocad or a 3d cad that I would be able to do some woodworking drawn up on that. And have them printed out through the Mac mini that I have. I have gone as far as searching through or at least googling around without any luck. Blender I know would be very limited to me on this since Blender does 3d but it's 3d animation. I'm just looking to do sketch's that would be able to do that even on a 7 year old mac mini. And given the option to print in 2D or have it slightly in the 3d with the dimensions on it. Mainly its for personal use over here. Has anyone else come up on this type of application in open source.
