Dwg Compatibility of ProgeCAD and AutoCAD

A reader writes:

A few days ago I had dilemma: I make a dwg with AutoCAD (native file), edit it with ProgeCAD, and open it again with AutoCAD. Will the dwg file be corrupted (objects etc)? I mean, will the process from AutoCAD to ProgeCAD lose info? And then in AutoCAD the drawing wouldn't be the same as the source file?

The drawing will not be corrupted, even though AutoCAD may display a dialog box insinuating it. Nearly all drawing entities are preserved during the round-trip. 

It is possible that some advanced AutoCAD entities might not survive the round-trip. I have not tested recent releases of progeCAD and so I do  not know the program's capabilities.

One of two changes might occur to certain entities:
        - they disappear from the drawing
        - they change their form, such as becoming a series of lines and arcs

The best way to find out is simple: create a test drawing in AutoCAD that holds all the entities and properties that you normally use, and then import it into progeCAD. Look for differences.

progeCAD has the maximum level of compatibility with AutoCAD drawings, so basically you will not experience any loss. Please note, reopening the file with AutoCAD a message saying the drawing was made with a non-Autodesk technology will be shown but this doesn't mean you are going to lose something. It simply means the file was saved with a different from Autodesk application.
