I’m trying to fillet two lines to join them on their edge.
This is the file: https://www.dropbox.com/s/25r1xpfh8li8bk0/why.3dm?dl=0
In Rhino Windows 5 SR10 it doesn’t work, the red lines won’t join in the corner.
The same file works fine in Rhino Mac 5.0 beta:
In doubt, I used _SetPt to lay all lines on the same Y level. But doesn’t solve the problem.
Any advice? Thanks
It’s working over here.
I used Fillet with Radius=0 Trim=Yes Join=Yes.
but I dont know what your Absolute Tolerance is?
Wow, same tolerance, but I’m working in millimeters.
Jordy, looks like you’re on Rhino 4.
I’m on Rhino 5 SR10, latest update, can it be the difference?
No I’m using: Version 5 SR11
Also tried with 0.001 in millimeters. Also working.
Maybe try the service release candidate?

Works fine here, V5 SR11 RC…
Note that as an alternative to using Fillet 0 to do this, you can use the Connect command…
