Creating surface from lines

hey everyone, So i have a vertical surface that im getting the perimeter curves of. I want to move the top line (with respect to z axis) down 3/4" then rejoin it into the list and make a new surface. The surface will be just 3/4" shorter… I have done everything but be able to create a new surface. Does anyone know why? is there a better way to do it?

Im guessing the “rectangle.bycornerpoints” doesnt work because my points dont go in a clockwise rotation. (Dont really know how to reorder the list and keep the same structure)



thanks ahead of time for any responses


I have found a way that works but it think it could introduce error with more complex surfaces. Still looking for a better way to do this.

Please let me know if you have any other ideas!

Try Geometry.Trim
