Dxf Export of Dimension

[wandererfan]

Everything OK. see attached screenshot. But diameter symbol is showing some strange values & angle arrow both in one side.

A new version to check. Note that I set FC diameter symbol to "%%c", so it looks funny in FC, but it looks good in DraftSight.

Thanks,

Hi @wanderfan
I'm testing the DXF export from techdraw
I was trying with a design that has a bspline inside the View.
Here the FC file and the exported DXF.
The DXF doesn't get imported in DoubleCAD nor in DWG TrueView of Adobe.
It does get open in LibreCAD, but if I try to save it with a different name, LC crashes...

Please let me know if you prefer that I would start a new thread, something like: "TechDraw: DXF exporting of a bspline"

EDIT: exporting the dxf as we did here:
https://forum.freecadweb.org/viewtopic. ... 10#p221906
then LC will not crash and the bspline will be correctly exported and the dxf could be open in DWG TrueView

Perfect. See screenshot

Is DXF R12 support spline. I think it is available from 2000 version.

Not handling bspline would be a DXF exporter de-featuring...

May i ask why still using R12 revision of dxf? autocad 2000 uses R14 already...
R12 have some serious limitations see https://knowledge.autodesk.com/support/ ... toCAD.html

[wandererfan]

Perfect. See screenshot

Great! I'll push changes later today. Thanks so much for your assistance.

[wandererfan]

See attached freecad file. If techdraw page dxf exported, position of one view changes.

Actually a problem in DrawProjectionGroup code. Thanks for finding it!

Because the Dxf formatting program we started from (from HeeksCAD originally) only supported R12. Once we get R12 working reliably, we can add later specs.

The changes between R12 and R14 are huge, while R12 is a very simple format, R14 introduces a lot of annoying mandatory things, like the need to have all the blocks numbered in correct order (which is annoying when working with templates), etc. But indeed we'll need to go there at some point, because important entities like ellipses or splines were introduced only in R14.

The interesting thing is that many FOSS apps will gladly accept R12 files that contain R14+ entities but most commercial apps don't
