Hi Avila, can you please post the .3dm model file in it with the vertices that you want to reposition?

The most general way would be to select one vertex, then use the Transform > Move command, click on the selected vertex as the base point for the move, and then click on the other point as the target point for the move.

Depending on how the points are configured like if they are from the same curve or different curves there may be other shortcuts like drag one vertex to the other or squish them together using the edit frame corner scaling handles.
