Surface from network of curves - Edge Problem


I am attempting to create a surface from network of curves, but the top edge appears to be broken into multiple segments, causing the tool to fail. I tried using the merge edge tool, but it says the edge is already merged (despite being in 3 segments). How can I fix the broken edge?

Hi Mason - the curve you trimmed with is a polycurve with three segments - by the time it is pulled to the surface it is no longer tangent between the segments. Untrim that surface, make one clean BlendCrv, adjusting it to be pretty close to the surface and trim with that.
That said, it looks like a simpler surface than a network might do well there, I’ll have a look in the morning if no one jumps in.

Here is how I think I’d do this -

Hi Mason,

I just untrim that surface that wasn’t clean and then I trimmed againd with a planar surface.
Having a cleaned surface and now you’re able to do the network surface.
I hope is clear…

untrimming and retrimming the surfaces worked! Thank You!!
