I am trying to edit a custom tool box that I created 4 years ago. The tool box is really simple, it just sets up attributes for given features that we want to place.For some reason I can no longer edit this tool box to add more features or edit existing ones. When I right-click in order to add or edit a tool the option to do so is dimmed/greyed out. I've looked through the forum but everything is outdated or completely unrelated to my issue.Any guidance will be appreciated!Thanks in advance!
Ad Rod points out the variable MS_GUIDGNLIBLIST must point the the dgnlib that contains your customizations, see:
Once the variable points to the file you can then customize the toolboxes through the customize dialog.
