I use Creo 4, in the drawing
when I move a note or a bubble, there are always positioning constraints that appear, is there a way to disable this function?
Someone can help me ?
There is an existing Idea for the same, you can vote...
Another possible work around is by creating vertical and horizontal snap lines.
Have their intersection away from those pesky perpendicular or tangent snapping conditions.
Snap the corner of the leader to both lines, then move the lines into desired position by adjusting their spacing (can double click the snap line)
This issue was fixed in May 2020 with the release of 4.0 M130 with the addition of controls to disable and change the behavior of the constraints.
