Sprocket / Chainring with calculating in values

Postby Boneshaker » Sat Feb 20, 2016 3:14 pm

Hello to everyone,

first of all, thank you for this wonderful piece of software.

I'm using freecad 0.16, for sprockets / chainrings, I didn't use additional workbenches or macros.
For size of sprocket the number of teeth could be entered in spreadsheet »Werte«. Angle of single tooth is calculated in »Sketch«, »Number Polar« in Array equals number of teeth.

Is there any wiki page for calculating in values?

I found the answer myself: http://www.freecadweb.org/wiki/index.ph ... xpressions
Maybe my previous searches had the wrong keywords. ;)
