To get the best out of 3D printing, it helps if you can design your own parts. In this tutorial series, we will learn to use a free 3D CAD program to do just that.
In this episode, I meet a frequent viewer request to cover sketch dimensions and constraints in more detail. We design a mainboard adaptor mount using a dimensioned diagram, then build a frame around it.
A future video is planned where I design a more complex part from start to finish to show all of the little problems and how to fix them.
All of these tools have a dedicated help page - Onshape sketch tools help menu: cad.onshape.com/help/Content/...
