Errors in drawing created by RealDWG

[alanchen123]

I use RealDWG to create a new drawing(see attached 36-3(no annotative)_new.dwg), then add some lines and arcs to the drawing, then I try to open it in TrueView, but get an error message, see attached screen1.bmp The error message just said "Errors were detected in the drawing" and ask me whether to recover it, I choose to recover, then in the recovery log, I see there are no errors found in the drawing, see attached screen4.bmp In that case, I am really confused: 1. Why the drawing created by RealDWG has errors? 2. Why no errors are actually detected in recovering the drawing? Thanks

The drawing does have problems.  I opened it in a debug build of AutoCAD and it had a problem with annotation scaling roundtrip data being incomplete which then caused other problems.

What version of RealDWG are you using?  And, can you show (or send me) your source code for the app that was used to create the problem drawing so that I can try to figure out what might have gone wrong?
