Hi,
Thank you for your tips, it works (easy but not very intuitive ;-).
But one more thing: I've some hybrid symbol from manufacturer, and I can't set the 3D orientation. I attach an example: I'ld to draw a vertical arch, with the spotlight facing the audience. If I take your Robin symbol, it works, and not with the Sixpar symbol.
I think something is wrong in the 3D part of my symbol, but I can't find it. Could you help me ?
best, steph
