Installation of as AutoCAD app

Run the installer.

Manual Installation of the AutoCAD app

This option is available for AutoCAD 2012 or newer as well as verticals. This can be done both while AutoCAD is running or not running.
Enter the below path in Windows Explorer address field and press enter.
Extract DimNotes.bundle.zip in the ApplicationPlugins folder so that a folder named DimNotes.bundle is created with all needed files.
It can look like this where jtb is an example of the user name.
PackageContents.xml should be found in the DimNotes.bundle folder.
To uninstall, delete the DimNotes.bundle folder.

Jump to the usage section.

Another Installation Option

Download the software either with the installer or without installer.

Extract the files in dimnotes.zip and run setup.exe. Default installation location is C:\Program Files\JTB World\DimNotes.

Or download without installer and place the files manually in a folder of your choice.

Notice though that you should have it on your local PC or special .NET security settings needs to be done. An error message indicating this can be something like: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

JTBDimNotes.dll needs to be loaded by your AutoCAD application and that can be done in different ways. Use one of the following options.

  • Use the command NETLOAD and select JTBDimNotes.dll. This loads the command in the current session only.
  • Create a menu command, toolbar button or palette tool using CUI and force load it before running the command.
    Macro or Command string:
    ^c^c(command "netload" "C:/Program Files/JTB World/DimNotes/JTBDimNotes.dll") DimNotes;
  • Use one of the AutoLoad...reg files. Double click on the file and accept to merge to the registry. This will make sure that the command DimNotes is available whenever you run AutoCAD.
  • Add the row below to your acad.lsp file so it loads automatically when AutoCAD starts.
    (command "netload" "C:/Program Files/JTB World/DimNotes/JTBDimNotes.dll")

When manually installed the included DimNotes.bmp can be used as menu command image or toolbar button image and DimNotes.png can be used as palette tool image.


Command to use is JTBWDimNotes or in older versions DimNotes.

Alternatively use the button on the Ribbon tab Plug-ins/Add-ins, panel DimNotes.


To register the software when you have purchased click on the Register button that is available when running the command DimNotes. Enter the register key you have got emailed in the text box.

If you want to deploy and register DimNotes to many users contact us for instructions.

Add Dimension Notes

Either you can pre select one or multiple dimensions or the command will ask you to select them.

Start by adding your typical notes.

JTBDimNotes.txt is the text file that holds the dimension notes. The file will be created when you start to add notes and have pressed OK. Use the Path button to change the location. The default location is in %appdata%\JTB World\DimNotes.

Select one of the notes.

Select the location where you want to place the note in relation to existing dimension text. The note can be added Above, After with space, After without space, Before with space, Before without space or Below existing text. There is also an option "Replace" to completely replace the text so the associative dimension text is removed if the text is <>. When Location Replace is used the checkbox "Replace Existing Notes" makes no difference.

If you want to replace existing notes select the checkbox "Replace Existing Notes".

Location option Replace can be used to add both before and after the dimension. Say the existing dimension text is 28 and the note is (<>) the result will be (28). Even notes using control codes, Text Symbols and Special Characters like
\A0;<> {\H1.5x;}\A2;\H0.71x;%%p0.1 can be used with this result: 28 ±0.1.

Solution to the following error is to right click on the DLL file and click on Unblock.
