Warning - When you delete the 'element' you will also delete these elements.
Many elements depend on (need) other elements.
When you add a Pin-Joint, you select two Points in two different Parts.
Thus, the Pin-Joint is dependent on (needs) the two Points.
If you delete one of the two Parts, MechDesigner must also delete the Pin-Joint.
The Dependent Elements dialog-box is a list of elements you will also delete if you continue.
