Cannot import 2D DXF or DWG files

[onebigfish]

Hello,

I am new to FreeCAD. I am familiar with 2-D drawing using AutoCAD LT and DraftSite. I want to import drawings I have done in DraftSite. I saved the drawings in R2000-2002 in both DXF and DWG. I installed the converter and manually set the path to the executable.

When I import the drawings into FreeCAD, I get nothing. I have tried a few different drawings and ended up with the same result. What is wrong, or what am I doing wrong?

This is an example of the output in the Python console.

Code: Select all

>>> Gui.activateWorkbench("DraftWorkbench")
>>> import importDWG
>>> importDWG.insert("D:/Desktop/TEMP/33034900.dwg","Unnamed")
>>> Gui.SendMsgToActiveView("ViewFit")

Try exporting in R12 or R14 DXF from DraftSight. You'll probably have batter luck.

It's a shame that Dassault Systèmes didn't include IGES import/export with the program.

Thanks for your reply Mark. I've tried exporting to DXF and DWG in the R12 and R14 versions, but got the same result.

[quick61]

Would you mind posting an example DXF file that is not working. Being exported in R12, there shouldn't be any real problems.

Certainly. Here is one of them.

[quick61]

Use R12 or R14 ASCII, don't use binary. Sorry, should of mentioned that before. The dimensions will not all work, but it looks like everything else will.

[onebigfish]

Thanks very much. It seems like R12 is the only one that works reliably with one of the particular drawings. The other ones do not work, or do not produce desirable results.

Is it that FreeCAD does not import any versions higher, or is it that DraftSight does not export them properly?

Yes. The real problem IMO is the screwed up and very murky exchange format known as DXF. I really don't use it much beyond trying to help those in this forum. Perhaps others that are more informed about the workings of the DXF format will chime in here and be able to help you out more.

can not open that dxf file either.

The file opened in DraftSight on Windows. I saved it back to R2000 ASCII DXF and was able to open it in FreeCAD, but all text and dimensions are gone, only the geometry (3 orthographic views) is visible.
