How to use "Slope of curve" and "Point on string" constraints?

[CNSZU]

Hello,

This is a puzzle for me. In sketcher I've found 2 constraint types that I can't figure out how to use. One is called "Slope of curve" and the other "Point on string".

Please advise.

OK, 'Slope of Curve' is is where you can select a point on a Spline and constrain the 'slope' or angle of the spline at that point to be the same as a referenced curve, usually a line (if you look closely at the icon for the 'Slope of Curve' constraint you can sort of see what I mean by the above explanation).

As for the 'Point on String', this is similar to a 'Point on Curve' except that it is not limited to only a single curve but rather will follow a set of adjoining curves which would allow the 'point' to move from one curve segment to the next as IF it were a single curve.

Thank you John, it's all clear now.

Just a few side caveats, if others have trouble: for the "Slope of Curve" constraint, it only applies if the studio spline type is by points (not by poles). And for the "Point on string", it only applies to a set of connected curves first created with the Project Curve command.
