3. Learn how to Create a Sketch
Watch the video tutorial titled "Getting started OnShape."
Watch the video again and again.
Within your own account, create a shape out of a rectangle (50mm x 40mm) and a circle (15mm).
Extrude to a depth of 20mm to create your first shape.
Helpful definitions and videos:
extrude - add depth to a selected region or planar face along a straight path. Create a new part or surface or modify an existing one by adding or removing material, or intersecting parts in its path.
planes - a flat surface on which a straight line joining any two points on it would wholly lie.
orthographic projection - a means of representing three-dimensional objects in two dimensions
