CurveToCam1[cnum, locuspoint1, {alpha, guess}, locuspoint2, {gamma, guess}, {delta, guess}] constrains the space curve defined by locuspoint1 to lie tangent to the spatial surface defined by locuspoint2 (locuspoint1 and locuspoint2 must be defined as parametric functions of alpha, gamma, and delta).
CurveToCam1 constrains one degree of freedom.

CurveToCam1 generates four constraint equations and introduces three new variables, alpha, gamma, and delta, hence constraining one degree of freedom.
• The points of contact on the cam surface and on the space curve are constrained to be coincident (three degrees of freedom) and the normal to the cam surface is constrained to be orthogonal to the direction vector of the space curve at the point of contact (one degree of freedom) yielding four constraint equations.
