Drawing Iterative Loops with breaks

[ta96]

Hello,

 

I'm evaluating Designer as I spend a lot of time documenting behaviour using loops. The attached are examples. I tried for quite some hours yesterday trying to work out how to create such diagrams. I made some progress. I have been able to create a nice arrow head and have some of the curves but I could not make the whole thing work as I would like. And what I did seemed to take an enormous amount of time. My conclusion? I must be approaching this incorrectly. 

 

So, I wonder, may I seek some suggestions for how more experienced Designer users would approach these task please?

 

Thank you.

Do you know about the so-called "power duplicate" method?

 

Here's a loop sample I made up in a couple of minutes. I started w. a tear shape, converted it to curves, broke the curve at the tip, and repositioned the nodes, one up and to the left, the other down and to the right. Drew some circles along the line. Grouped all, and used "duplicate." Moved the group off to the side, scales constrained around center, and lined the ends of the loops. Repeated the duplication, which carries forward the translation and scaling. The group could also have been changed into a symbol, and have the same power duplicate. That would allow one to make changes to elements of all the symbol instances at once.

You guys are SO clever. Thank you very much owenr and gdenby. I really appreciate you taking the time to provide this really helpful advice.
