I downloaded 0.19pre to test this design. Had some problems with 7-zip : doesn't handle correctly the WIn10 alias from "program files" to "programmes" in the french version. Fortunately 0.19 can be installed on any user directory.

Lot of improvements from 0.18 to 0.19 in the PartDesign WB. I could do nearly immediatly and without errors things which caused annoying "naming bugs" in the 0.18. Here is the result. The spreadsheed has been renamed "PS", shorter in the formulas and faster to type, for "Parameters Spreadsheet". I came to a new design in the clip sketch. Not fully automatic, but OK in most cases and easy to check. I added a central hub and rays to make coil windings easily with a driller. The rays can be cut out easily later if not necessary in the final use. I recommand to discard the first 0.18 version of this design to use only the 0.19, especially if it is intended to be modified in any way.

By the way there is still a warning at opening of the file : for the "median e.t. plane" I used just a segment to position it, and it creates this warning of two inertial values null. I don't know how to do it otherwise.
