Locking Permanent Dimensions

When you place permanent linear or angular dimensions, a lock control appears with the dimension. Locks
appear when you select
A permanent dimension.
An element constrained by a dimension. An element is constrained if it is referenced by a locked segment
or is a reference in an equality dimension.
If the lock is unlocked, the dimension value is modifiable and the element that it references is free to move
in any direction. You can click the dimension value and change it.
If the lock is locked, the dimension value is fixed, preventing any change to the distance between its referenced
components. You cannot click the dimension value to change it.
Selected dimension with locked and unlocked controls
Clicking on the lock switches it between the locked and unlocked state. Once a dimension is locked, you
must unlock it to change its value.
TIP You can also switch the locked and unlocked state of the lock by right-clicking on it and choosing Toggle.
