Assuming your object is transparent

You need a “real” object point to attach the glue point to.

For unfilled objects, you need to put the glue points on the contour line, which can be difficult to hit exactly.

For glue points on “empty space” I use a white fill with 99% transparency, which is fine in most cases.
