I have to admit, I didn' read through all posts in this thread.
Has it already been requested to have an "Upright Extrusion" option for the "Loft along Path" tool?
There are plugins out there that can do an upright follow-me operation. But none of them (as far as I know) can morph between two profiles along the way.
Therefore it would be awesome to have this functionality.
Ah, I see. That does make sense.
However, this behavior seems to stay with the geometry, even if you convert it to a plain mesh and explode the group. Could you find a way to undo this on conversion?
Hi Thomthom,
when modelling a sofa with your superb plugin I came across a peculiar behavior, that seems to occur with any geometry generated with SUbD, whether it is a live SUbD object or a plain mesh generated from it...
Surely you are familiar with the excellent trick of SketchUp, where the direction in which you draw a selection frame influences what is being selected.
Now, with a SUbD mesh, selectin in such a manner does work. If however you press SHIFT / CTRL or both to add or subtract from a selection, this behavior is reversed (or behaves in another, unpredictable manner). Can you reproduce this?
To make things easier, I have attached a file with a SUbD mesh on the left and an ordinary object on the right. Here you can easily see the difference when selecting using the modifier keys.
This is not a big issue, of course. But interesting nontheless 
I was relying on the SketchUcation Plugin to keep my stuff up to date. But that obviously didn't work. I just re-installed CleanUp³ and now got the same error message as cotty.
I then used thomthom's trick and did a first run, just Merging Faces and then a second, full cleanup. This worked!
So thanks guys. Now I have a new trick to use, when handling problematic models...
Hey Thomthom,
I do not know since when this is an issue. But with big models, the CleanUp porcess doesn't work anymore. Only when I select small portions at a time, does it clean up. If I select too many objects simultaneously, its not doing anything.
Is this a known issue?
Here is such a model. Do you experience the same problem or is it just my system
Working nicely! Very valuable tool for quick and clean quad face modelling.
Could you make it so, that the green / red color is removed when disabling Live Mesh Analysis?
That would show clearly, if the system is switched on or off.
haha, I could have sworn I tried that. But obviously I didn't. 
Thanks a lot
Hey guys,
I run into this problem quite often, where I model a shape, making sure, every surface is a quad.
But when I use SUbD to subdivide, it looks wrong.
When I then use the "Flip Triangulation Tool" of QuadFaceTools, I can see that some faces (marked red in the model below) are not being recognized as quads.
Does any one know how this happens? And more importantly, how to fix it?
Cheers,
Jakob
is there a Version that works with SketchUp 2016?
Bulk conversion of components to groups doesn't seem to be working (and is sorely needed when importing a 3ds-model, where every object is a component)
