Rhino.Geometry.Intersect.Intersection.MeshLine(...) BROKEN on Rhino7

the function Rhino.Geometry.Intersect.Intersection.MeshLine doesn’t work on Rhino7.
I always get 1 intersection point (0,0,0) and 1 facet (0), even when some intersections are expected.
I cannot distribute my plugin on Rhino7 for this issue.
It is working fine in Rhino5 and Rhino6.

I believe you need to update to the latest Rhino 7.4 service release candidate. There was a regression which has been fixed.

@piac knows the details.

Hi @donato1

there has been a hotfix for Rhino 7 SR3, and this is fixed in (7.3.21053.23031, 02/22/2021) and later.
Do you have updates turned off?
