A question about Point objects

When you position a point at the intersection of two lines, does Fusion remember just the actual X,Y coordinates of the point at the time you add the point, or does it remember that it's position is at the INTERSECTION of the two lines?

 

If you later move either, or both, of the lines, but so that they still intersect one another, although at possibly a different position along the lines, should we expect that the Point object will now be at that new location of the new intersection position?

My experience is that it does NOT remember anything about the two lines and their intersection, but rather just remembers the PRIOR X,Y coordinate where the two lines had crossed when the Point object was laid down at their intersection.

The apparent fact that it doesn't remember that's is supposed to be at an intersection is causing me a lot of problems. The same issue seems to arise when I draw a new LINE and position one of the endpoints of theline at some 2-line intersection.

The point will relate to the two lines ONLY if you constrain the sketch to do so.  When placing the Point, do not try for the line intersection but place the point Coincident to one line and then add another Coincident to the other.  The point will stay with the two lines if they are moved together or independently.

The key is how you place the point.  If you look for the "X" inference icon (a little hard to see in the image, see the screencast), that is telling Fusion that this is an intersection point, and it will remember it as such.  What this does behind the scenes is to create two coincident constraints - one between the point and each line.  You can manually do this, as well, using the Coincident command, but this is easier, IMO.
