Is there a way to make a custom riser profile for a stair? I have a custom nosing which also shows the steel angle shape parallel to the front edge of the tread to hold it up. I thought maybe I could use a custom riser profile to show the steel angle parallel to the back edge of the tread...but it doesn't seem like risers are handled by profiles. Oh and these are spiral stairs, so the front and back edges of the tread are not parallel to each other.
Any ideas? Thank you!
