Parametric Stairs in Blender #blenderarchitecture

Find out how to generate completely parametric stairs with Blender. Useful for architecture projects and shows a computational design workflow that is accessible via Blender's modifiers and vertex groups.

refreshing to watch a tutorial without Geometry Nodes 👍 thanks, nice setup

[juhada]

I love how you show the power of modifiers, even when geometry nodes has taken off, these techniques still offer surprisingly flexible stuff. Bravo. I'm sure I will use this technique in the future it's just too elegenat to ignore. Also, making an asset out of this seems like a good idea too. Thank you again.

As a beginner, I never appreciated vertex groups as much as in most of your tutorials. Now I use them a lot. :)

Very good class, thanks for sharing your experience in Blender!

Thank you very much, very elegant workflow, I had an issue with 4.0.2 all the bevels destroyed around the hook or vertex weight, no way back and impossible to open with a 3.2. I will try from scratch in the 3.2.

One of the best tutorials ever thanx a lot

How much I watch your videos, they are one of the best for architecture, and if you do it all through geometric nodes, it would be great to see. it's bad that you can only put one like

Looks great ! Always curious how this could be done in FreeCAD similarly.

😞 I'm having an issue with the landing portion of the tutorial. I'm able to get the upper portion of the landing to seal along the Y when grabble the empty but the lower porting connect to the ground doesn't scale. The upper portion of the landing is wider than the base of the landing. A triangular shape. Is there a problem with my vertex groupings? I checked to make sure all of the vertices were in that group but still an issue.

I found an issue with this tutorial. If you don't apply the modifiers & you wanted to use your own image textures, the base mesh is just a line and so you cannot unwrap it (it's greyed out). The finished object's surfaces will have really thin lines, based on the colors on the textures, stretched across the surface. e.g. If you have a wood texture, you'll have a striped black and brown surface. If it's a stone or stucco texture you'll have white and grey stripes.

Maybe this is just a newbie mistake.

Bevel didn't work ( corners didn't bend) what could be the reason?
