Fill in my knowledge gap :)

Aspire can do some 3D work.
This was done in Aspire

but for parts with curves, think a mobile phone mold etc you need 3D / fusion 360

For most part they are just built up from 2 1/2D parts that Sheetcam can handle fine.

Carry on as you are and jump later if needed. the time for the learning curve is far better spend doing what you can do.

Thanks all, i can see that most stuff is possible in 2 or 2.5d software - the big difference as said above is where parts must fit together and you need to make alterations without redrawing all the attaching points and parts - this is a real pain in 2d software.

I will carry on as i am but continue to play with F360 when i get a quiet moment.
