Do not upgrade .... the app is wrong ... when shade is closed the application

No Unicod Support


No Unicod Symbolics supported in Drawings, very strange for that expensive app.

Good job IMSI


This app is very good at what it does. Takes my 3d models where I can't take my desktop PC. The visual styles make the drawings look amazing on my iPad. All the paper space layouts are there, the way they were drawn on the original. Clear lines and dimensions. Zoom, pan and rotate in wireframe, hidden line and rendered mode fast and smooth. The x-ray mode is very useful. Well worth what you're asking.
Very nice!
