Thanks for the detailed replies.
I’m looking for a format like STEP or STL that I can put into a CAD or 3D printer slicing software. Through work, I’ve access to Solidworks, Ansys and AutoDesk, so I can switch between formats with some limitations.
I’m basically looking at ways to 3D print surfboards (hats off to the contributors to this thread: Glassing 3D Printed Boards).
I need some 3D models of surfboards to work through the process and to see if it is feasible or not.
If I can’t get my hands on a few test / example models, I’ll sign up to the Shape 3D ‘Design Pro - 3D Export’ plan for a month, but would prefer to save the AUD $80.
I’ll also contact Thomas and Nick, thanks @jrandy
