This can be achived in QCAD by using the Mirror tool - Main Menu > Modify > Mirror ...and follow the prompts.

Sketchup is a 3D 'sketch' modelling program, in Sketch-up you can change the views to what plane you need i.e. Top view, side views etc.

Azz131: Thanks for the screenshots. However, the DXF file would be more helpful for testing and helping you with the problem.

If I understand the problem correctly, only the spline at the right is rendered incorrectly by Sketchup. One simple solution would be to explode the splines in QCAD (Modify > Explode), then save again. This will convert the splines into polylines which are generally better understood by applications reading DXF files.

Thanks. I've filed a bug report at:

A workaround is also available (reconstructing the mirrored spline).
