SketchUp Layout to QCAD with dwg2svg

[Rudolf]

OS: MACOS 15.6.1, QCAD-Pro V 3.32.4.0

My task is to convert Sketchup Layout files to be used for further processing in QCAD.

After some research I found the converter DWG2SVG. So I exported in Layout to DWG: 0UGElektro.dwg, placed this in the some directory as the converter and defined an output file in the user area to avoid file creation problems.

This is the command in Terminal of MacOS:
rudolfms@MacServer Resources % ./dwg2svg -o /users/rudolfms/Rudolf/0.work/2D/0UGElektro.svg -f 0UGElektro.dwg

The resulting file is (nearly) empty.

The converter runs in debug mode and produces the following warning messages:

What do I do wrong?
What can I do?

The DWG file only contains two references to image files:

2025-07-20 UG Elektro.images/000.png
2025-07-20 UG Elektro.images/001.png

These images are not stored in the DWG but referenced on disk.

When exporting to SVG, the SVG file will also just contain references to these image files.

My task is to convert Sketchup Layout files to be used for further processing in QCAD.

It is a DWG file ... A native CAD format supported by QCAD ... Why converting them to SVG?
I would further process these in QCAD as DWG or DXF files.

The best option is to place a copy of the bitmap files in the same directory as the DXF/DWG.
If QCAD can't locate it at 2025-07-20 UG Elektro.images/*.* it will also scan the drawing file path for such a file.

Thanks for the quick answers.
It looks like my problem is more the Export from Sketchup Layout, because the png contain only the imported background with the house drawing and not the vectors I draw on top.
See attached file.
I now will explore another path.
I will use the attached PDF and import it directly to QCAD. I found out that with this way vectors remain vectors.

Thanks a lot so far, I may come again, if the above mentioned path gives me difficulties I cannot manage.
