I'm currently designing a staircase for a client, and i need to be able to create the swept path shown below in sheet metal. I have attached my skeleton model that has the basic structure to it.
here's the image of what it will roughly look like:
and below is where I'm currently at with the design.
It must follow the 2 arcs shown below in plan view and be at the heights set by 'Stair Rail Profile Sketch 1' to 'Stair Rail Profile Sketch 4' - this is 100mm off each step leading edge.
The make up will be a top panel, and 2 side panels.
I've tried numerous methods, splines, arcs, projected curves etc but I can't seem to get the profiles to match to create a nice curve.
Appreciate and help or advice to get me out of a bind.
