How can I make path points easily selectable?

When creating path points, the path point generation code places the path point object instances at exactly the same position on the z axis as their path. If the path point type has a 2D rep with a z offset of zero, then the point is exactly coplanar with the path section ribbon and this might lead to you seeing rendering artifacts.

It can also make it difficult to select a path point: sometimes clicking the point might pick it, or it might pick the path section instead.

To make path points easier to select, you can set a non-zero z origin offset (e.g. -0.5) on the representation used for Path Point (the base type used when generating path points). Any path point types you create will inherit this rep and its default offset.

For example, if you decide to use a rep called circle, a simple 2D circle, for your path points, when you import the image in MODEL IMPORT, in addition to any scaling you apply, also set the z origin:

Assign this rep to the Path Point type in MODEL ASSIGNMENT and then any path points generated using this rep, will "float" above the path:
