However, the 'Basic' version of Shapr3D can only export 'low-quality' STL and 3MF files - which may be OK for 3D printing but may prove to be very limited beyond that (no DXF files for instance). I've just watched some intro videos on Shapr3D and there were certainly some aspects that reminded me of Solid Edge, which only runs on Windows (not Mac or iPad) - although I've no idea if Shapr3D uses the SE 'engine' or not. I do not count in this the amateurs who digitise a full loco or traction engine. I cannot see how an casual amateur (like me) using a CAD program for a few hours, then forgetting about it for a month until maybe wanting to draw another bracket can justify more than fifty quid for full ownership. I was quickly put off by the statement that the free version only allowed 2 models and the pro version cost more than a lathe every single year.

I had a quick look at its webpage a few days ago when their advertising department had picked up on my searches for tutorials on another CAD program. My photos are 90° rotated and I don't know how to rotate them correctly, but you can see the idea. My first items are simple pieces to learn the CAD, and are hinge/connectors to replace the broken ones on my clothes horse ! I can certainly say it is easy to use and get the hang of. to the drawn 3D shape. You can quickly sketch a rough shape, then go round and type in the actual dimensions, to refine it, and it all changes accordingly. £300 for a year seems very reasonable, or there is a limited free version I think.

It is quite intuitive - I have never used CAD but these parts did not take me very long to create, and it is very easy to add fillets etc. On the Shapr3D website there are a lot of tutorials and forums for advice and help. My primary use at the moment is learning to make parts to 3D print. Most of my work will be at home, but it might be useful to be able to design on the iPad, away from the desk. I believe it uses the Solid Edge CAD software internally, with an interface to work on an iPad with an Apple pen, or on a Mac with a multifunction mouse.

It is my first CAD and it runs on iPad and Mac, which is what I need. Well I just downloaded it and tried the intro, it looks easy to use and I'll persevere! I don't have the time to have a go myself at the moment but thought it may be a solution for some of the folk enquiring about CAD options.

There is a free basic version and a 14 day free trial of the pro version. Just noticed Shapr3D, a 3D modelling tool that I had not noticed before.
