I am wanting to add an icon to a popup list tile in a Dialog Control Language (DCL) file to use in an AutoLisp script. From AutoDesk's website, link here, the example image shows this as being possible. From the information it has provided, I have gathered that part of a string needs to be added to the list
attribute. This leaves me with one final question, how do I link an icon with a popup list tile?
As far as I'm aware, this is not possible using standard DCL (and the developer documentation is therefore misrepresentative). You would need to use OpenDCL to achieve this functionality.
