Object Locking

The grading object reacts differently to the changes you make depending on

whether it is locked or unlocked.

Unlocked Object: When the grading object is unlocked, it is reactive to

changes and automatically updates. You can change the grading properties,

use grip editing on the footprint, slope tags, and region tags, or use the

AutoCAD editing commands (move, rotate, copy) and the grading object will

automatically update slopes and daylight lines.

Locked Object: When the object is locked, it is not reactive. You can use

some AutoCAD editing commands (move, rotate, copy) to modify the

grading object, but the object does not update slopes and daylight lines

while it is locked. When you unlock the object, the program immediately

updates the slopes and daylight lines. You cannot use the grip editing feature

on a locked object.

NOTE

The AutoCAD LIST command displays the lock status of the selected

grading object.

Locking a Grading Object

If you want to change the grading properties or use grip edits, then the grading

object must be unlocked. Any changes you make to your project, such as

redefining a surface that is used as a grading target, do affect the grading object

if it is locked. When you unlock the grading object, it is updated with the

changes you made.

NOTE

You can use some AutoCAD editing commands to modify the grading

object when it is locked. The program automatically updates the grading

object with these changes as soon as the object is unlocked.

To lock a grading object

1 Select a grading object in your drawing and right-click to display the

shortcut menu.

NOTE

The grading object is unlocked by default.

2 Click on Object Lock. A check mark displays to the left of Object Lock

indicating the object is locked.

NOTE

Click on Object Lock to clear the check mark and unlock the grading object.

NOTE

If you are using only AutoCAD Land Development Desktop without Autodesk

Civil Design, then the lock status of the object displays when you use the

AutoCAD LIST command, but you are not able to change the lock status.
