The point-curve constraint restricts a fixed point defined on one part to lie on a curve defined on a second part. The first part is free to roll and slide on the curve that is fixed to a second part. The curve on the second part can be planar or spatial or open or closed. The first part cannot lift off the second part; it must always lie on the curve. A point-curve constraint removes two translational Degrees of freedom from your model.
When you specify the location of the point-curve constraint on the first part, Adams View creates a marker at that location. The marker is called the I marker. The I marker can only translate in one direction relative to the curve. The I marker, however, is free to rotate in all three directions.
You can use the point-curve constraint to model a Pin-in-slot mechanism or a Simple Cam Follower mechanism where a lever arm is articulated by the profile of a revolving cam.
When modeling a pin-in-slot mechanism, the point-curve constraint keeps the center of the pin in the center of the slot, while allowing it to move freely along the slot and rotate in the slot.

Curve/Edge | Select whether you are defining the point-curve constraint along a curve or an edge of a part: ■Curves - Splines, chains, and data-element curves are all considered curves. ■Edge - An edge is one of the wireframe outlines drawn on a solid. For example, you can use a Parasolid object representing a cam that you imported into Adams View. |
