I want the offset to be as planar as possible on the open edges/ holes at either end, and its veering off at one side.
Is there any way to constrain this? I cant just trim it after, because im making the corners of the projection curve rounded.

Thank you.
I have tried rebuilding the network curves and the network surface to no avail, so im assuming its the shape which is doing this. Are there any other tools I can use to make an offset?
Hi Simon,
Are you able to give a little more detail?
Andy
if you want the edges/surface to offset towards one direction only, you can use _ExtrudeSrf or _CopyâŠ
that said, i imagine these will also give you undesired results as the distance between the two surfaces wonât be consistent unless the surface is flat to begin with.
as a way to better understand/visualize what OffsetSrf is doing, maybe try the command on a cylinder and a sphere⊠what it does to those is the same thing itâs doing to your surface.
Blimey that was quick 
I want the open end on the right (the smaller piece) to be pointing directly away from the orig surface and not diagonal when I offset (or as close as possible)
The end circumference of the base tube shape is planar and a single surface, so im not sure why one side is veering off (bottom right of top left picture).
Doesnt need to be a solid as I can rail that after.
i donât think itâs veering off⊠when you offset the surface, it moves in the direction exactly perpendicular to points on the original surface⊠the arrow youâve circled signifies the ânormalâ direction of the surface at that point and you can see itâs moving at a 90Âș angle.
Exactly correct. So, go to the top view and trim your offset surface back. Iâd make a straight line right above the open end and use that.
This is a technique we practice in my Rhino class. We call âMake it bigger & THEN trim it back.â Catchy, eh?
But, it actually makes your job easier as you no longer have to make a surface EXACTLY to another boundary ⊠which, you can see, frequently fails.
hey Simon⊠i recorded a method which you can use to tweak the surface pretty quickly without sacrificing too much precision on this particular shape:
itâs rhino for mac but all the commands will be the same on windows as well.
Thats a good workaround. Thank you for taking the time to make that.
