Question: I can not view my drawings from my AutoCAD based vertical application such as AEC, ACA, MEP, Civil 3D, etc.
Answer: Setting PROXYGRAPHICS = 1 in your drawing file from your vertical application should allow it to be viewed in TurboViewer and TurboViewer Pro. Other workarounds would be saving a copy and flattening your custom objects by using the "aectoacad or -exporttoautocad" command in your vertical application then re-send it to TurboViewer/Pro.
