TrueType Text Exploding failures

I'm very new to cad, so maybe i'm doing something completely wrong, but i feel this might be a bug ..

When i make a text in a truetype font (Verdana for example) and than Select it and choose Modify, Explode the output looks good in QCad. Image
(example downloadable here: http://netcontrol.nl/qcad/welkom.dxf)

But when i import it in my favority CNC software (usbcnc, www.edingcnc.com) there's obviously something wrong here... Image

I just dived a bit deeper into this problem, and tested the same function in CamBam and that works great.
I just noticed that it seems something to do with the conversion of "spline" as the parts missing are all 'splines' Image

Am i doing something wrong or is this a bug ?

@Andrew: Great software, i'm absolutely buying a license from you. It's a very low learning curve for me. Keep going on this way!

This appears to be a bug (or rather a limitation) in the other software you are using ("usbcnc"). It most likely simply does not support spline entities at all.

One potential fix is to also explode the splines in QCAD:

- Draw True Type text
- Select text and choose 'Modify' - 'Explode'
- Select all entities and choose 'Modify' - 'Explode' again. Lines and arcs will not be affected by this, splines are converted to polylines with line segments.

If usbcnc does not support polylines either, you can repeat the 'Select all' / 'Modify' - 'Explode' routine again to explode those as well.

By the way: I've noticed that your drawing rulers and some other GUI elements (property editor title bar) are black. This is wrong and likely caused by the theme that is used by your Gnome or KDE window manager.

A possible workaround for that could be to start QCAD with an alternative fixed style, for example:

./qcad -style plastique

Other supported styles are: cde, cleanlooks, motif, windows

@Andrew: Man, you're quick and RIGHT!

See for youselve...
The second explode http://netcontrol.nl/qcad/qcadwelkompoly.png
and the correct result in USBCNC http://netcontrol.nl/qcad/welkompoly.png

I'm contacting Bert Eding (developer usbcnc) for this.

Thanks.

Right again.. I tried the "BlueSteel" style.
Rulers come back when i choose "none" or another one.

Thanks
