I'm cann't seem to figure out how to come up with the start points for the helix command. I am including a drawing showing these dimensions. Tha actual drawing does not have any of these lines in it as it is in 3D.
The green is 3D solids.
The yellow is known dimensions.
The magenta is unknown.
The size of the green objects will be variable as well as the radius of the circles depending on what the user chooses The program is to make 3D spiral stairs on the side of a storage tank going to a platform. I have everything else working fine I just need to get the helix's drawn properly so I can extrude the stringers and hand rail. I've been trying to find a way to calculate them but haven't had much luck so far.
Thanks
Troy
