Custom functions in relations?

Custom functions in relations?

Custom functions in relations?

is it possible to define a custom function in relations - f(x)?
an example would be the involute function or (a couple of them probably) to calculate the base tangent length of a parametrized gear.
if it is, how?

RE: Custom functions in relations?

also, is it possible to drive only one or two features via a family table?
i am trying to make a parametrised sprocket and would like to drive the key dimensions via such a table (or something similar).
also i would like to calculate the base tangent length over XX teeth, nr. of teeth to measure it and so on for an accompanying drawing.

after that i'm planning to do helical and hypoid gears, if time permits.

but i don't think i will be able to accomplish it fully without defining my own functions (for involute curve...)

RE: Custom functions in relations?

you can see this video. Maybe helps you,
