Extrude Surface Normal.3dm (178.1 KB)
I have not been able to discover the proper sequence to extrude this surface inward normal to the surface by 1 mm so as to create a closed polysurface. Any help would be much appreciated.

Iâm only seeing one srf and 6 crvs. weird crvsâŚ
Iâm not seeing a ânormalâ direction for that commandâŚ
Weird, I canât see a simple solution. Maybe âfinâ in combination with âoffsetsrfâ and/or offsetnormal?
I thought extrudesrf had a normal direction option âŚ
Assuming âoffsetsrfâ is using ânormalsâ technology:
Meh, got a weird anomaly there from that approach:
Maybe âfinâ the border:
Nope, âfinâ has anomaly too:
Yeah I guess Rhino wont automatically trim that data on âoffsetnormalâ either:
Maybe a loose offset will work idk.
A single surface should not have a crease.
Run DivideAlongCreases, and Explode the resulting polysurface.
Then offset each one and clean up the overlap.
