parametrisation of three angles in different steps.

Hi all.

I am stuck with a parametrisation problem.

I have angle A1 which is a function of two other angles A2, A3, A4 and distance D1

A1=fn(A2,A3,A4,D1).   ALL THESE ANGLES AND DISTANCES ARE PRESENT IN DIFFERENT FEATURES

the exact relationship looks complicated to be calculated using hand and even with transformation matrices.

Is there a way in solidworks,where i can modify one angle, say A3 to get A1 keeping other values A2, A4 and D1 constant.

I would like to know of any method for this..

Cheers

Ashwin.
