Stairs Maker

What is Stairs Maker?

Stairs Maker is an add-on for Blender that allows you to create stairs with railings with lots of different customizable options.

When the Add-on is enabled, in the side panel in the 3d Viewport, you'll see the BB Assets Panel. From there, with a simple click on a button, you can transform any selected object into a stairs or a railings object. 

How does this add-on work?

It applies a Geometry nodes modifier to the selected object. These applied node trees create stairs and / or railings objects, but no Geometry nodes experience is needed since all that matters for the user happens inside the side panel of the 3D viewport.
Once the stairs (or railings) are created, this panel populates with lots of options, all organized inside dropdown menus.

Every option is explained in detail in the User Manual that can be downloaded HERE for free.
