Not Happy

After paying the $35 I was expecting to get an app that was seamless. This is not the case. App is not user friendly and it does not show any annotation ( titleblock, Dims, block anno ext..) after marking up the DWF I would like to tie text to the mark up but the text does not appear just the box or cloud to clarify the area. Not worth the money, should have been free.

Best cad markup app

Update works well for for my DWG, DGN, and 3D PDF files. Wish it supported texture maps though. Good tech support.
