If you look at an end view of the coils previously posted here, you will see that they are either cicular or square. However, if you look at the end view of the coils of most real transformers, they are not square or circular but a rectangle where two sides are longer than the other two sides. I want to create a coil that wraps around that kind of rectangular shape. There may already exist some way to do this, but I am just learning FreeCAD and learning it seems very difficult because there are so many Workbenches and Macros.
There was, if I recall, a rather long thread here with someone getting really deep into the shape of wrapping wire. He created a website with a lot of data about it. Hmm...yes found it: https://forum.freecadweb.org/viewtopic.php?f=3&t=47426
But, I don't see the website he had at one point but there are some Python scripts in the thread.
This is what I have so far. https://drive.google.com/file/d/1c2Vcnm ... sp=sharing I want to wind coils around the U-shaped objects to generate small voltage and current pulses, but I don't know how to do that in FreeCAD. The objects with red and blue ends are magnets. The red and blue ends are the poles. Eventually, I want to tie the two coils together but two of the contacts touch the rotating switch so that the coils are open for parts of a cycle and closed for the other parts of a cycle.
I know very little about FreeCAD. I'm using the Draft Workbench and trying to follow what Mads Leth Danielsen did. First create one turn by entering line segments point by point, then rounding the corners and using Array to duplicate it and then Part Workbench to sweep. I'm sure there must be a better, faster and easier way to do it. I still have a lot of work to do to get what I want.

Anything that doesn't use the Draft workbench to draw is faster...
Did you look at the links I posted where the guy posted his Python for wrapping inductors?
Star Trek II: The Wrath of Khan: Spock: "...His pattern indicates two-dimensional thinking."
Yes, I looked at the torroidal windings, but I don't have a torroid and I also do not have the skills (or desire or time to learn) to write python code, scripts or macros. I don't know very much. If it isn't simple, I probably can't do it - unfortunately. It doesn't help that I will be 75 years old next month - age has its effects!
