Divided Surface - UV grid not parallel

[Anonymous]

What is the reason that UV grid of the bottom surface has an angle to it?   I'd like it to be parallel to the top surface.  The grid rotation for both surfaces are 0.  How do I fix this?

Thank you,

Try using the Align Tool.

the Align tool does make it parallel.  However, I have this family tied with parameters, and when the parameters change, it'd make UV grids rotated in a different angle and would need to be re-aligned.

For the top surface, I don't have to that at all, so I'm wondering what controls that by default.  The length and angle on the two sides are the same, similar to the two sides on the top.

Share the family.

Here's the family

I recreated the planar form by selecting only top and bottom lines then the divided surface stays parallel to the lines.  I think you could still use all 4 lines to create the form properly, but the order of selection may matter.  I didn't have time to test it.

Here goes.

Could you please let me know how to fix that?

That works perfectly!  Thank you very much.
