drafting over a napkin drawing

[a3bksll47]

Is there anything in FreeCAD that would allow for an imported image file to be situated into the background so that lines can be drafted over it?

The image workbench has this function: Create a planar image in 3d space
Place the image 1 mm below your sketch

Neat. Thanks. I'll try it.

Using Create a planar image in the 3d space in the Image workbench. The file is .png, and measures 1520 x 2688.

It would appear your graphics card/driver compatability with Qt5 is causing the error, please see https://forum.freecadweb.org/viewtopic.php?t=32637

If you're really struggling, an alternative is to download the 0.19 Qt4Py2 version https://github.com/FreeCAD/FreeCAD/rele ... nVS2013.7z and unpack it to a new folder with 7-Zip (you don't need to make any changes to your 0.18 installation, they run side-by-side). You just need to make a shortcut for the 0.19 src\bin\FreeCAD.exe to launch it.

Ok I'm reading that, and there's a lot about graphics card interactions with versions of Qt. This one is a Quadro P2000.

I'll get that 0.19 release and see if that works. Thanks.

Can you attach the image you are trying to use? It might be possible to do this another way.

[a3bksll47]

Success. Thank you all. I'm running 0.19 with Qt4 and everything is working.

I thought about raster to vector, but for this something like the Image workbench is a better subtractive medium for me.

After reading all the pages of https://forum.freecadweb.org/viewtopic.php?t=32637
I can add that it appears Intel CPU on-board graphics was probably causing the problem on my computer too. Run with graphics processor (NVIDIA) works for both the 0.18.16117 Qt5 version as well as the 0.19 Qt4 I just tried.
