Re: Advanced Staircase generator plug-in v4.0
The Staircase Generator is a plug-in designed for Sweet Home 3D that allows users to create highly customizable 3D staircases. The tool features a comprehensive parameters menu for fine-tuning dimensions, structural elements, handrails, and midrails. It also includes an integrated 2D Shape Designer for creating custom handrail profiles.

Real-World Application: Whether you are an interior designer pitching a sleek, modern glass-railing loft, or an architect ensuring a multi-story traditional home meets building codes, this plug-in provides the exact geometrical control you need.

Re: Advanced Staircase generator plug-in v4.0
Hi Xlance,
v4.0 looks really great and I love the more detailed options!
However, one flaw that I found is that when you select "U shaped", the generator will create a "U shaped with bottom landing instead" so something seems to be linked incorrectly there.

Thanks for the nice work!

Re: Advanced Staircase generator plug-in v4.0
The error is on line 441:

				return createUShapedStaircaseShapes(stairCount, firstStairCount, 1, turnStairCount, stairWidth, stairDepth, stairHeight, treadOffset, treadThickness, true, riserThickness,

should be

				return createUShapedStaircaseShapes(stairCount, firstStairCount, turnStairCount, turnStairCount, stairWidth, stairDepth, stairHeight, treadOffset, treadThickness, true, riserThickness,

Re: Staircase generator plug-in
Where do I find the new 'generate staircase'? I don't have a menu titled 'Tools'.

Re: Staircase generator plug-in
Has anyone created advanced stairs using v4.0 of the generator ?
It would be really of benefit to see users' creations to help guide further development smile

Re: Staircase generator plug-in
Cool! One quirk of British building regulations: A landing area must at minimum be a square, each side equal to the width of the stair. i.e. the middle landing of your Y shaped stair would be illegal. To make it legal you'd need to overlay the 3 squares in the smallest space, if that makes sense.
