Hi,

I have polygons greated by an eps import.
How can I convert a polygon into a curve that can be used for ral extrude later on?

I want to make tubes from the poly edges and use those as some kind of neon lights late on.

Just select the points along the poly's edge and ctrl+p.

Thanks, it does something,
but how to edit the curve to get the desired shape back?

select endpoints (6) use chamfer   :)

curves can take some time getting used to, here are some videos that covers some curve tricks / gotchas

Just do a two point poly of the path and use the negative edge trick in layout to make tubes, much quicker.

True, for rendering. Users unfamiliar w/this trick should be aware it doesn't generate geometry. So, it is either the best thing since sliced bread, or semi-useless, depending on your needs. ;)

True. Itís only for rendering inside lw not for making geometry. Itís sad that we canít extract geometry from negative edges and hypervoxels, would be very useful at times.
