Polybevel on polyline?

Hi!

I've created a simple polyline with 3 points and I'm trying to bevel the mid point. The polybevel doesn't work.

Any advice?

Ok, so part of the problem was that my Poly Bevel sop was set to primitive instead of points. But now, I can't use my point group (midpoint) in the poly bevel and it also gives me a weird result.

seems to be a bug - if you type the group name in manually it works.

I can type it manually but as you can see in the image, the bevel has a gap(missing segment) and the end points get connected for some reason…

I have to say that I created the 3-point line from scratch with a detail wrangle. I did not use a Curve sop.

Ran into this the other day. Polybevel seems sensitive to point/vertex ordering.

Your vertex order is different from your point order. Adding a sort node with sorting set to “by vertex order” will fix the issue. You can also fix the vertex order by changing how you wired them together in your “polyline_90_turn” wrangle. There you call addpoint in top-mid-bottom order, but then call addvertex in bottom-mid-top order.

try re-arranging the verts:
addvertex(0, nprim, pnttop);
addvertex(0, nprim, pntmid);
addvertex(0, nprim, pntbottom);

edit: didn't see previous answer

Thanks for the solutions!

In a way, I'm glad I made that mistake. Now I understand more about it!
