Hi All,
Thank you for reporting this issue and I am very sorry about the experience!
Unfortunately, I have to tell you that this is a generic issue with DWG-DXF export and it requires a big overhaul for the add-on itself. The font handling engine when exporting to DWG, or the Font-Style conversion does not work reliably at export without a DWG Template file.
If the Style does not exist (and if it cannot be created at export) the mapping may not even happen (it will map to the style "Standard") or it may happen, but it will just create a new style that refers not to the ARCHICAD Font defined in mapping, but to some default (txt.shx / Arial).
Since this would be a big task to work on (overhaul for the whole add-on), this might take a while to be implemented in a future ARCHICAD version. As DGSketcher has pointed out, a DWG template can be used as a workaround in this situation for a correct font export to DWG.
The proper steps should be as following:
1. Start a new Drawing in AutoCAD.
2. Type the STYLE command
3. Create a new font style with a name (this is the name you'll use in the translator)
4. Set up this new font style
5. Save the drawing as an AutoCAD Drawing Template (.dwt)
6. Close the file (so that ARCHICAD can open it)
After that, you can browse this DWT in the translator and create the desired font mapping.
I am truly sorry for the inconvenience! I really hope that we can start this project soon, so that we can improve the DWG export/import experience!
Thank you very much for your contribution and enthusiasm!
Best regards,
Minh
