Hi I need to SubDLoft pairs of closed curves but would like the surface sections to remain completely straight. I’ve played with the options but nothing seems to address this. The resulting surface needs to be SubD.
Any quick fix for this? Thanks, Adam
Might help to upload the files.

Try also sweep2rails with end sections and cross sections where needed.
How does that result in a SubD surface, which the OP says is required?
I’m still learning here, but looks like if you split those curves before you loft, you can have better control over the result.
Here I split your two curves, then lofted both sections using SubDLoft with Corners, and increased the number of sections.
You can then join the two surfaces if needed.
That’s the result of answering on the phone while riding a bus without reading thoroughly… I just read the headline and looked at the pictures. 
my bad!
Thanks for the workaround. Hopefully I can avoid splitting the curves but if there’s no other way I’ll do this! Cheers
Hi @adam.d.hills ,
I’d do this with with BlendSrf > Rebuild > ToSubD…
If you did every other pair of curves this way, and kept your rebuild numbers the same, you could then use Bridge to get the in-between SubDs. This would be ideal if you plan to join the SubDs into one preserving the creases or not.
I hope that helps.
Wow - thank you so much for this! Really appreciate your time and clear explanation.Looking forward to trying it out. Cheers!!
