Staircase Stringer Problem
Staircase Stringer Problem
(OP)
Hi all - got an interesting query. We have a staircase to model and detail design: I've attached a model, which has been created by a colleague. I've not looked into it in depth yet, but will be doing as you read this! The basic dimensions have been supplied by an architect and we have to fill in the blanks.
The issue is the staircase stringers: the specified material for these is 100x250x10 RHS (although if it makes life easier this could be fabricated - i.e. four pieces of 10mm thick plate welded together). We think the outside stringer can be made, but the inside is throwing up some funny shapes, which is making us a bit worried about producing a nice model and further still, fabrication.
Any questions, please ask and feel free to make suggestions!

This seems acceptable, but I'd still welcome other options.

If you definitely want to do it from your own sketch, and are using a 3D path, you need to sweep the section sketch along the 3D path. Not loft. And if it doesn't look as you'd expect, play around with the appropriate setting for profile orientation (I'd suggest using "normal to path", which I think is the default anyway for sweep).

The finished model, although actually not very heavy on parts count, is quite impressive and when it gets built I'm sure it'll be a belter!
