try: for cga

Hi, this is a thing which is in my unformulated wish list for a long time.

Wondering if it would possible to have something similar to the try | except python version, but in cga.

This would be mainly for geometrical manipulation operators which "silently" fail to process a rule geometry (thinking of roofs in certain weird cases, offsets, setbacks etc). When that happens there's no way -in cga, for example with some case/else- to catch those errors because derivation stops at faulty shape and keeps input geometry in its current state (meaning if at beginning of a rule set, most of the cases without a proper material, name etc).

Of course these problems are somehow catchable in cga log afterwards, but I think (imho) it would really streamline and robustify generation process when dealing with massive batches.

Anyway, this is not urgent...

It's not what you asked for, but resetGeometry might be able to help in some (probably not all) cases (though it might be tedious).

HI , no unfortunately, it's impossible to catch those pure geometrical error at the moment, as I said derivation stops and leaves rule geometry -as is- as a terminal leaf. No matter what you code after. This is a very special tricky usecase, I should probably package an exemple.
