how to stop a curve?

[simo]

hi to all,

when I enter a coordinate (x or/and y) as function of a parameter t by a equation, the parameter t will vary from 0 to 1. Is it possible to stop the coordinate x for a determinated value of t? For example when I draw the profile of a tooth (for a gear) by a involute curve, I would like that the curve stops at the outside circle. How can I do this?

thanks!

You'll have to build the correct solution into the equation. t will always vary from 0 to 1.
