This tutorial explains how to cut a shape out of a 3D model in Onshape, for example, cutting a hole out of a shape.
The two examples below show a shape (hole) cut right through the object from one side to the other (using the circle tool), and a partial cutout that doesn’t cut all the way through the object (using the rectangle tool).
Watch the video below to see how to cut shapes out of 3D models.
