Contour problem

[waqgera_dawaa]

I was expecting 8 curve after I contour a curve, but i ended up with 18, Why is that happening

?

Update: Known Bug Right Now

Looking here it seems your Union operation didn’t go through so you are ending up with 2 branches of contours here. Likely this is why.

There has been a duplicate curve bug in Contour for several weeks:

Contour creating duplicate curves

When I use the contour component, I end up having duplicate curves. I am not sure why it is making duplicate curves. Has anyone else expereinced this? [image] [image] Visually, it shows 2, but its actually 4 of them, as per the panel shows. [image] Edit: I tested this with my Rhino 6 and it creates no duplicate curves. Seems to only make duplicated with R7

I don’t see it that way. The wire on the ‘Shape’ input of Contour is not doubled, meaning only one item, so SUnion likely succeeded. Contour always generates a branch for each contour plane because they might have two or more intersections, depending on the shape.

@Joseph_Oster

likely succeeded

I confirm that you are correct.

I even tried it on just one box without joining the forms and sit ends up with a double curves so I don’t think the problem is with SUnion.
