Catenary columns in Kangaroo

[diff-arch]

Welcome @at00,

@at00

My initial attempts utilizing tutorials on youtube have involved creating anchor points around the edge of roof. This first attempt, in section, simply offset anchor points for the columns. Whilst these appear to be catenary arches, the peaks of the arches are extremely low.

Which YouTube tutorial are you referring to?

It appears that the anchor points are simply fixing in place individual mesh vertices, which probably is not a good idea here, since the columns of the vaulted structure all start/end at basically an apex point, and would need to get chopped off later?

With my second attempt, I tried to ‘button’ to the tops of the lower arches to the correct elevation with anchor-points at their pinnacle. Evidently, however, it didn’t work, and I was left with these bizarre forms.

Look, without at least seeing the topology of the mesh that you’re feeding into Kangaroo, it’s really hard to say what’s going on here. It would be best if you could at least upload a relevant example file!

For Kangaroo, your mesh topology matters a lot. The cleaner, the better!
By “clean”, I mean a quad or tri mesh with rather equally sized faces and a neat, continuous edge/face flow, probably something akin to this:

Pinching individual mesh vertices to form columns frankly doesn’t seem like a sound idea, unless they’re explicitly your goal, but then I wouldn’t stick their peaks into the foundation.
