Скачать или смотреть Sketch constraints in detail - 3D design for 3D printing pt10

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: https://cad.onshape.com/help/Content/...
