Why use Onshape?
Why use Onshape?
3D model in Onshape. 3D models allow the design to be tested and refined before manufacture.
This is a Drawing file from Onshape that can be used to make templates for manufacture as well as engraving the pattern on plywood
AR model that can be used to show clients what the table will look like before manufacture. Colours and materials can be tested also
