Loft a simple subD plane for a cushion shape

[Revel_Woodard]

Hello-

Can’t seem to perform this sweep to create a cushion shape. I’d like to sweep a SubD plane around the quarter radius rails to create a quarter radius cushion.
Been doing my due diligence with tutorials but still coming up short. Tried using the existing faces / edges of adjascent cushions, tried making new edges / faces. Tried leaving shape open on one face as that’s what seems like the tutorials show https://docs.mcneel.com/rhino/7/help/en-us/commands/sweep2.htm

Any advice much appreciated,

best,

Revel

Hi Revel, try:

1. DupBorder on one of the flar vertical faces marking the end of the arc cushion.
2. Revolve >SubD output, 10 sections on the center of the arc, 90 degrees.
3. Rotate a copy of the first vertical subD the same 90 because the other one does not quite line up as far as I can see.
4. Join all three
5. RemoveCrease around the hard edges.

thanks guys. I still cannot get the subD sweep to work, but I did have success with the revolve.

Question, why the shape can not be closed (grey out) ?

Going to try this one too, for a project
