Hello From Perth (Australia),

I just bought an IPAD Pro especially to use the SHAPR3D app (I could not wait for the Windows version!) … Great work by the developers!!

One command that I used a lot in AutoCAD was the trim command.

It would be so much easier to trim in SHAPR3D if the knife-edge line was highlighted (in RED for example)

Right now, I am using getting the Trim command to work by trial and error…

Is there an easier way or do I just need more practice?

Cheers,  
Pierre
