My old "stair.lsp"

[Drafting Teacher]

This is a lisp file I've used for years and it's been very useful. It creates a profile view of stairs risers and treads using only the predefined calc. for risers. It asks for tread length only. I wonder if it can be modified to include balusters and rails?

I'm gonna try playing with it myself to see what happens. Is it OK to post code directly or would I need to upload the compiled lisp file?

I think it would be a good idea if you could at least show an image of what the new elements should look like.

Better to upload the LISP or add it into the LISP box (using the <> button).

 

For the rails, it should be easy to do, specify the maximum and minimum spacing - or one every step, just need to work through to draw it out.

Downloaded it. I'm gonna see what it'll do. Although I prefer the 2d, 3d will work just as well. Thanks.

My modified lsp was a qualified failure. It's attached but I'm missing something in the command string.

One issue with stairs is the rules regarding the design of stairs. Where I am there is an Australian standard. The standards vary around the world.

 

 

Looked at code why would you not just pick 2 points top of stairs & bootom of stairs ? The X and Y are calculated from these 2 points. Using these values a  range of min max tread height and width is displayed so can choose. Will have  a look for my stairs, have to go now.
