Lock an element or keypoint

Do one of the following:

• In a 2D profile sketch, choose Sketching tab→Relate group→Lock .

  In draft, the command is located on the Home tab.

• In a 3D sketch, choose 3D Sketching→3D Relate group→Lock command

Click an element or keypoint to lock the element and prevent it from being modified.

You can apply a Lock relationship to multiple elements in a single operation. After selecting an element, you can press Shift+Select to add more elements to the set or deselect elements from the set. You can also drag a box around the elements you want to select, and then apply a Lock relationship to them. You can press Shift+drag+select to add more elements to the set.

When geometry is locked, it changes to fully constrained (default color=black).
