Finding extremities of a free-form curve

Finding extremities of a free-form curve

Finding extremities of a free-form curve

(OP)
Greetings all!

The task is to find extremities of a free-form curve with the purpose of aligning datum planes against them. I have found solution based on sketcher - see attached file. Is it as good as it gets, or am I missing something? Is it possible to directly align a plane again such extremity?

RE: Finding extremities of a free-form curve

Attached is a solution using a function called 'Measure Extremes' which will define points at the extremes of the curve. Note that inaddition to the points, which I then used to define the Datums, there are expressions giving you the X,Y,Z values for these points. Note that these points are associative so that as the spline changes shape or size, the 'Measure Extremes' points will update.
