QCAD

The R2010 DXF and R2010 DWG formats produced by QCAD 3 RC5 cannot be opened by Visio 2010.

Error message:
Cannot open file. The file may not be a DWG or DXF file, it may not be in a supported version of the DWG file format, or it may be corrupted. Check the file and try again.

Prerequisites:

1. QCAD 3 RC5
2. Visio 2010 with all updates installed

Steps to reproduce:

1. Open QCAD 3 RC5 and create a basic drawing. Save using the default file types (R2010 DXF or DWG)
2. Open Visio and create a new drawing.
3. Go to Insert tab and click CAD Drawing. select drawing created above.
4. Observe error message

Additional info:

• When I use Save As in QCAD 3 RC5 and select any previous file format, Visio can insert the drawing. The problem I’m seeing with this part is that on a more complex drawing, the spacing/alignment is messed up (items aren’t in their proper spacing).

Other observations with a more complex file:

• If I open a R2010 versioned file in Solidworks and then save it back out as a dxf file again, Visio will properly insert the drawing with correct spacing/alignment

• If I open the file in QCAD 2.2.2.0 and then save as Drawing Exchange (*.DXF) it inserts properly in Visio with correct spacing/alignment.

• If I open the file in QCAD 2.2.2.0 and then save as Drawing Exchange R12 (*.DXF) it inserts in Visio but the alignment is off (similar to problem above).

File attached for reference.
