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

That’s a great question about the textures. In Sweet Home 3D, getting the lighting right can be half the battle, especially when you're trying to make the 3D view look realistic without it getting too cluttered.
I’ve found that if a specific texture or wallpaper looks a bit "busy" or overwhelming in the render, it helps to check the tonal values first. Sometimes I'll run a quick preview of my source images through this https://www.thetoolapp.com/color-to-black-and-white-online/ just to see how the contrast looks without the color distracting me. It’s a handy trick for making sure your patterns aren't going to clash once you hit that "Create photo" button.

Once again SPAM from Sindrela_Casper. Don't click the link.
