The following are general usage instructions for LayerApps:

(1) DDLyrAdd: Adds user-specified Prefix, Suffix, or Both to all or a selected set of Layer names.
(2) DDLyrCas: Changes Layer name case to 1^st Letter Uppercase or entire Layer Name to Uppercase or Lowercase.
(3) DDLyrF&R: Finds in Layer Names matching character set and replaces with new character set.

Note:  For DDLyrAdd, DDLyrCas & DDLyrF&R: You can perform any of the Options on separate sets of selected Layers as many times as needed. Click on the Apply button for all the operations to run and upon completion have the on-screen window reappear again showing you all the changes.  Click on the OK button to complete the operations to finish the command Click on the Cancel button to just dismiss the command without making any changes. Also, the following Layer Names are always excluded because these cannot be changed: Layer 0, Defpoints, Xref Layers.

(4) DDLyrOn: Current Layers turned Off can be selected to be turned On and Thawed if Frozen.
(5) DDLyrTh: Current Layers Frozen can be selected to be Thawed and turned On if Off.
(6) DDLyrVpC: On the left Layer Colors can be selected from a large custom 255 AutoCAD Color Index swatches applying to Layers selected in the List box on the right. Color Numbers are shown in the Layer list preceded with a “-“ if there are Layer Color Overrides.

Note:  Unloaded or Orphaned Xrefs are not supported for showing or removing Layer Color Overrides. If the user wants to use LayerApp’s CTB files (within the Layer Apps folder are Metric & Imperial scaled Color Style Tables), then choose Colors based on the recommended 6 groups of Black Line Pen Weights ranging from Extra Bold (Cyan), Bold (Yellow), Wide (Magenta), Medium (Green), Fine (Red) & Extra Fine (Blue). Click on the Info button to set the option to “Include CTB Files” for selection in AutoCAD’s Plot command.
Note:  For AutoCAD versions older than 2022, the user must invoke AutoCAD’s Options command and click Cancel in order for the CTB changes to take place in AutoCAD’s Plot window.

(7) DDLyrDes: Layers Description property can now be easily modified using the following operations: Case/Edit/Find & Replace or Filtered out for listing. Additional operations available to change the Layer’s other properties are: On/Off, Freeze/Thaw, Lock/Unlock, Plot/NoPlot, and Color using the large Color chart similar to DDLyrVpC.
(8) The LyrAppsInfo command can be invoked from within each of the seven added commands by clicking on the Info button. LyrAppsInfo opens an app window summarizing all seven new commands with their logos, a Version History button to access a log of version number & description, an option to include the provided CTB files in AutoCAD’s Plot window, another option to select and Show the LayerApps Toolbar along with the Publisher Privacy Policy and product contact information.

Note: With all seven LayerApps the total number of Layer items is always shown at the bottom of the Layer list box. Also after each app runs successfully, you can always use AutoCAD's Undo Back option to revert back to the previous state prior to running the command.
