Freecad tutorials pdf3/19/2023 Switch over to the isometric view, set the pad parameters for the correct depth of extrusion, and you’ll get an awesome filled solid. The tool we use for extrusion is Pad, so click on that. Click Close on the Tasks bar, and you’ll end up with a few options: Create Sketch, Pad, Pocket, Revolution, and Groove. Once we have our part drawn and constrained, the Solver on the left hand toolbar will tell us we have a fully constrained sketch. Slicers allow you to scale a print anyway… FreeCAD is metric only, so I’m designing everything around eigths of an inch. Note that I really don’t care about the absolute dimensions of what I’m designing. Now it’s time to move on to the third dimension, extruding our thing up 7/16th of an inch. After a little trial and error, we end up with something like the pic below, a fully constrained sketch of most of our switch base: Finishing off our ‘thing’ is just a process of drawing lines, arcs, and fillets, constraining them, and tearing your hair out at the inability of FreeCAD to show you the one unconstrained element in your sketch oh my god. In the last installment of this tutorial, we went over installing FreeCAD, the basics of parametric modelling, and drawing a few circles and lines. Here’s the Google Scanned copy of the 2nd edition. If anyone out there has the 1st or 2nd edition of Engineering Drawing (French, 1911 or 1918), please scan it (its public domain) and post a link. My copy is in dead tree format, and I haven’t yet built a book scanner. It’s from an 80-year-old book on drafting.Ī few people have asked me for a. Our Thing, And Where We Left Off Last Time Read on for the second part of our FreeCAD tutorial ![]() Here’s some links to previous Making A Thing tutorials, doe: ![]() It’s an amazingly powerful tool, and not it’s finally time to complete our model of a strange object ripped from the pages of an 80-year-old drafting textbook. Last week we took a look at FreeCAD, a free, open source parametric modeller. It’s time once again for another installment of a Making A Thing tutorial, where I design the same part, over and over again, in multiple 3D design software packages.
