WISH: command to merge and join triangular surfaces

What do you think of making a command that can delete and merge into a single surface dislike those surfaces (srf red), which do not allow, subsequently, to perform, for example, shelling or anything else? (This kind of surface they often generate with tapered extrusions).
A command similar to “MergeAllFace” …

Reconstruct a portion surface it’s easy, but when these are so many is very wasteful to rebuild all surfaces, one by one.

Or more drastically, you should write all the code of the tapered extrusions!

I wish Rhino wouldn’t add them unless they were absolutely necessary.

In fact, I think I should write the command code! Many other modelers in tapered extrusions achieve clean and unique surfaces, even Autocad!

I really don’t understand what it is that is stopping you. When you get stuck with a line of code, the support on the developer category here is excellent!

Wim, I think a command such as “extrude tapered” generating that kind of surfaces is to be reviewed! You can not do it all by hand! I think this: should review the code and how this generates the tapered surfaces.
