I thought that when a curve was 3D it would automatically get pulled to the surface for trimming?
But not in this case it seems:
curve-wont-trim-surface.3dm (123.3 KB)
Curve is closed and polysurface has no gaps
What is the issue?
the behaviour is a bit different for surfaces and polysurfaces.
your example is a polysurface.
_explode
it and then
_trim
the 3 individual surfaces
_join
them back together
use
_gcon (on the new edges, between the surfaces/faces)
and
_EdgeContinuity
to check if the result still is what you re after…
to see the deviation
_crvDeviation
from the initial curve and the new (pulled) edge
hope this helps - kind regards -tom
Hi Robert -
I’ve put this on the list as RH-84408 Trim: Fails on Polysurface
