My Attributes are Missing

Issue: My attribute text in my title block is not shown. My Layer is Thawed and On. What gives?

Your attributes may be turned off. To return to default use this command.

Command: ATTDISP
Enter attribute visibility setting [Normal/ON/OFF] : N

Normal is default. Invisible attributes are not shown whilst others are.
Many Land Desktop users change this to ON so the profile attributes appear. What they forget is that they should use Normal to change it back, not OFF.

Error: Unable to write data to locked layer: ???

Do you get this error when opening a drawing file in Land Desktop?
Background Info:

A block named "ADCADD_ZZ" gets inserted by LDT into the 1st layout tab. This block includes information about the name of the project (database) that the drawing is attached to and the drawing setup information.

Solution:

- Change the "ADCADD_ZZ" block layer to Zero (0) and/or unlock it's layer.

- Since you can't select the object with a mouse you have to use something like Quick Select to grab it to change its layer.

How to repeat this error:
- Create a new file using Land Enabled Map.
- Lock the current layer then save & close.
- Open the same drawing using LDT and you'll get a message box with the Unable to... error.
