Hello, and thanks for the answers and ideas,
I started with the cube,
and when I try to draw curves through the cube,
it cuts either nothing, or strange results.
(I went through the tutorials and can make crowns :-)








maybe it´s just a lack of imagination what exactly needs to be done?

by the way:
the picture from the harp is carved by hand, band-saw etc.
My skills are there - still It would be so handy to have this drawn.

best regards, ska234
