I would like to lock one single wall in my plan so that it cannot be moved, but not affect any other walls in doing so. How can I accomplish this task?
A single wall can be quickly and easily locked by assigning it to a unique layer, and then locking that layer.
To lock an individual wall
Open a drawing in which you would like to lock a single wall.
Select a wall using the Select Objects tool, and click the Open Object edit button to open the Wall Specification dialog.
Select the Layer panel. Notice the layer that the selected wall is placed on by default, and then click the Define button to open the Layer Display Options dialog.
The "Walls, Normal" layer should be selected by default. Click the Copy button to copy the layer. The new layer should be called "Walls, Normal 2."
Click once on the new, copied layer so it allows you to rename the layer. Type a new name for the layer, such as "Walls, Locked", and click Enter.
Notice that "Walls, Locked" has been added to the list in the Layer Display Options dialog. Click one time in the Lock column, or check the Lock checkbox, to lock this layer.
Locked layers are indicated by a padlock symbol in the Lock column.
Click the OK button to close the Layer Display Options dialog and return to the Layer panel of the Wall Specification dialog. The selected wall is now on the "Walls, Locked" layer.
If it is not on the "Walls, Locked" layer, click the drop-down arrow and select "Walls, Locked" from the list. Click the OK button to close the dialog and return to floor plan view.
In floor plan view, the wall's appearance will be unchanged, but you can no longer select, move, or alter the wall in any way.
There are still some cases, such as adjusting the wall type's definition, where a wall on a locked layer could be moved, so you should always verify your wall dimensions are accurate in your final plan.
To make changes to the wall, you will first need to unlock the layer it is on:
Select Tools> Layer Settings> Display Options to open the Layer Display Options dialog.
Remove the padlock in the Lock column for "Walls, Locked".
Click the OK button to close the dialog. The wall and any other objects on this layer are now unlocked and can be edited as needed.
