Hmmm .. With difficulty, but - it seems - I understood.

We call such a pipeline "dancing with a tambourine".
All this is very nice, but I can't understand why, why should I do a lot of these useless actions (and still keep all this in my head), if I can - stupidly - open an object in spaceclay, delete a fillet (if it was created by mistake) - and continue to work calmly without wasting time on all these body movements (which you so kindly and diligently described)

And I'm not talking about the pipeline, I'm asking about the meaning !!

In theory, I can climb to my apartment on the 5th floor using ropes and climbing pitons.
But I prefer the elevator!
