I recently started playing around with FC Gear and I'm very impressed with it. Thanks for all your work on this looo! I've run in to a difficulty with making an internal gear for a planetary gear system, however (see screenshot). The steps I take to get this far are:
- create Body (Part Design WB)
- make sketch (circle) and pad (Part Design WB)
- make involute gear with beta = 30 degree, and double helix = true (Gear WB)
- select gear and use Boolean Cut operation (Part Design WB)
Lastly, I don't have this problem for straight, non-helical gears. Using a single helix (i.e. not a herringbone), I get the spurious face on just one side, away from the x-y plane.
I'm using the FreeCAD AppImage on an up-to-date Arch system (installing FreeCAD is presently difficult to impossible on Arch).
Thanks in advance for your help.
