Constraining a Spline

Constraining a Spline

Constraining a Spline

(OP)
Is there a "good/easy" way to constrain a spline in a sketch? Right now I have a dimension going both vertically and horizontally to every control point with a formula for a percentage so when the OD of the hole grows and shrinks the entire spline grows and shrinks that same percentage.

Is there an easier way?

Thanks as always!!

RE: Constraining a Spline

Just constrain the ends and run the spline through the points but don't constrain them.  Then select Insert -> Constraints... and select the 'Uniform Scale' option.  Now as you move the ends, the Spline should scale in a proportional manner.
