How do I change the image editor used by the add-in?

The image editor that will be used by the add-in to annotate the issue captured can be changed using various methods. Please refer to the procedures below if you'd like to use another software such as Gimp, Pain.net, etc:

From Windows' interface:

This is the easiest way to set this up the one that I would recommend. It does not require elevation permissions from the system administrator and can be changed quickly when needed. As BIM Track uses the .PNG format to capture the issues, you will need to change the file type association from the shell. To do so, simply right click an existing PNG file on your computer, select "Open With…" and the "Choose another app". At this point select an app from the list and check the "Always use this app to open .PNG" option. At this point, when you will annotate an image in BIM Track the selected image editor will be used instead of paint.

From a registry key:

This may be the most complicated way to perform this change and this is addressed to advanced users as it requires a modification in Windows' registry thus requiring elevation permission from the system administrator. I strongly suggest performing a backup of your registry key before applying any change. For further information about this procedure please see the link below.

From BIM Track's config file:

When you install BIM Track, a configuration file that can be edited by the user is created in the "AppData" folder. Various changes can be made to that config file but what we're interested in here is that you can override Windows' image editor to a specific tool that will be used for BIM Track only. If you prefer not changing the default image editor for your Windows' environment but use a different one for BIM Track, this procedure makes it possible. However, the downside of that this is that you will have to perform this change every time your update your BIM Track add-in as a new config file created with each update.


  1. Open Windows file explorer.
  2. Navigate to the following path:
  3. Open either Revit or Navisworks folder and the year associated to the program you use.
  4. Locate and open the following file with a text editor (Notepad is fine):
  5. Locate the following string:
    <add key="annotateToolPath" value="" />
  6. Enter the path of the desired application between the brackets (""). For paint.net it should look as follow:
  7. Save the change and from now on this tool will instead be used for annotation using the add-in.
