Hi Guys,
I'm relatively new to autocad, self taught. I do glass railings, and I've mastered using 3d autocad to layout and design my flat panels, but now I'm trying to do curved stairs.
The fabrication company needs a flat dxf with a separately specified radius.
I use a total station to shoot the nosings of the stairs.
I'm working on a trial design to get the workflow figured out before I quote one that's coming up.
1) to model the stair rail, am I best off to do a helix starting from the bottom of the stair to the top of the stair, copy it to make the top edge of the glass, and then use that, or make a cylinder and slice away the non-stair portions
2) is it possible to make a helix based on 3 or 4 points, like you would an arc?
3) If I create several arcs based on different nosings on my stair, is it possible to get the program to make a best fit line, so I get the best arc that is the closest fit for all?
4) once I've designed the glass in the curve, how do I unroll the panel along the radius, to get the flat panel the glass company needs to cut. From what I've found in my searches, it sounds like I may have to invest in autocad inventor for this.
Thanks in advance

It sounds like you should use Inventor for this, because Autocad 3d is a dinosaur that wasn't made to flatten or rolling out parts.

Thanks for your help. I've talked to my autodesk sales rep and he's going to get me pricing for inventor and inventor LT. Any recommendations for which one I need? I'm going to download a trial to see if I can figure it out. Does it run similar to my existing autocad, or is it a whole new learning curve again?

At least AutoCad has direct modeling, if anything history based modelers are the dinosaur. Bricscad has sheetmetal (unfolding) options and uses direct modeling, which will be much more familiar to the OP. Unfortunately AutoCad does not as far I know of.
