polynomial to define a curve in mechanical desktop?

[rotarypower]

Is it possible to enter a polynomial to define a curve in mechanical desktop?

I read as many help topics came up with keywords polynomial, but could not find anything helpful.

Searched under keywords here and did not find a match either.

I got some help from a timely friend, and he recommended using spline to join arc segments with given points.
Not exactly what I wanted, but it will do for now.

I have not been able to find any think pertaining to this kind of activity even beig permitted.

Why would that be?

Are other more advanced programs capable of this?
