Only on a flat Z-plane - these are 2D Tools...
Although some like Fillet work in '3D' too...

There are several 'reglue' plugins around [there's even one within my HolePunch tool menu!]
However, I wrote this one a couple of years back and Jim spotted it wasn't 'indexed' - so here it is...

It works best with >=v2014
This is the oldest version I have...
SectionCutFace+_v2.6.rbz
or try this...
SectionCutFace_v6.2.rbz

In my UK jurisdiction, and I suspect many more, you are not allowed 'winders' but 'tapered treads'.
The calculation of the dimensions is convoluted.
The minimum 'going' is 50mm [2"] and any tapering tread at the centerline must have a 'going' measured square to the nosing equal to all the other non-tapering treads.
For non-domestic wider stairs the measurements are taken measured in from the sides - about 1/3 each.
The 'going' is not the 'tread' dimension - the overhang of the nosing is taken off the tread size, so it's the 'plan' dimension.
When you get to anything other than a simple staircase it can become very complicated to 'automate'.
In the UK a helical stair [aka 'spiral'] even has a set of alternative British Standard staircase rules which differ significantly from the usual stair Building Regs - you need to tell the local inspector which one you're using otherwise you could fail.
I've mentioned before about the handrail requirements in the regs to extend 300mm [12"] beyond the top and bottom nosings in many situations, and the landing's going the be 300mm longer than the stair width.
Also, staggering the nosings by one going as the stair turns at a half-landing [or top] means that the handrail transitions smoothly without any need for a vertical portion to make it work...

Being 'unsigned' need not be a problem.

Edit your native Extension Manager settings - Loading Policy > Unrestricted

Restart SketchUp and version-compatible, but 'unsigned', extensions [i.e. usually older] will then load OK.
Only install extensions from trustworthy sources - like SketchUcation, the Extension-Warehouse and a few developers' sites which offer direct downloads...

Version 2.0 is available from the PluginsStore.
https://sketchucation.com/pluginstore?pln=TIG_points_cloud_triangulation
It fixes issues with delauney3.rb using Constants in away that newer SketchUp versions Ruby chokes on, t also includes some tweaks of the main code - Layers v. Tags etc, and the RBZ is now signed...

And if you erase that file you will need to re-validate the licenses...

This works in all newer versions of SketchUp.

Any error messages in the Ruby Console ?
Are you following the detailed instructions.
It hasn't been supported for sometime - the author has stopped all development on his extensions.
Although it's old it has been reported as working in versions up to a few years ago...

I was also looking ! It seems to be a simple issue with 'FixNum' being deprecated in the newer Ruby version, replaced by 'Integer'.
I'll edit the file and publish an updated version asap.
Under the author's notice it's allowed...

You seemingly haven't installed it from its RBZ.
If you simply copy the ../Plugins/HouseBuilder_extension.RB file over to the newer SketchUp version it misses the images to make the toolbar-buttons [and worse!]...
Unfortunately the original author was in the dim past [20years ago] and made a half-baked extension loader file, and he didn't give his subfolder the same name as the RB file.
The new[ish] auto-migration tool assumes this file/folder naming convention and so it misses out copying the subfolder of images [and some other vital support files that are in that folder].
To fix it you need to find the whole HouseBuilder folder [and its contents intact] in your older version's Plugins folder and copy that whole folder over into the newer SketchUp version's Plugins folder.
When you startup SketchUp it should now find the subfolder and load the buttons' images and the other vital support files...
