1. The ability to extract polygons from more than one object at a time.
The current extraction function will only extract polygons from the first object you selected and will ignore all others.

2. Extract, flip, and merge.
I'll often want to extract a polygon simply because I want an object to be double-sided. Unfortunately, this involves those three steps above (and much more clicking if I accidentally unselect a group of polygons after extraction) when it might easily be done in one single routine.

You could call it...transmogrify. Very Happy

And yes, that's exactly how it could work (although, it'd be best if it worked on several objects at once, but I could imagine how that might be complicated to code).

I'd like to see how many other people would use this function, though, so you're not adding in something that only I would use.

How about we call it what it's used for, something like"make doublesided", and have it check each selected polygon whether it already _is_ doublesided or not (only doing the magic thing when it isn't).

It's just a problem when you want to continue working on the object. Extrusion, inset, even moving will only consider one polygon at a time. You don't want to select both, front and back polygon. That would be horrible. So I'd vote for a IsDoublesided tag for polygons. If that would be possible.

Call it simply "double".

Anyway, if I had a single triangle, which was double-sided (so it's actually two triangles with reverse winding), and I did an Extrude, I would expect the Extrude to create a prism, with the bottom triangle at the bottom, and the top triangle at the top.

There are some questions, though: when selecting, do you select one triangle, or both? I'd assume you select only the triangles facing the camera when clicking.

Also, selection in general is one of the harder problems of 3D modeling programs. How do I get at those features way in the middle of the object I'm currently working on? But that's a different question entirely :-)
