String Shape Editing
You can now fine tune the shape of your strings from within StairDesigner. This makes it easy and very fast to add or refine the curve of your strings to complement your design goals.
Elliptical Stair Set Up
A good way to go about this is to start by drawing a plan of the stair in a CAD package (in this case DraftSight). The ellipse is broken into arcs in DraftSight. Then we go over to StairDesigner and use it's curved stair functions to complete the set up.
