This was how I discovered the importance of the object model path. I would appreciate some best practices guidance on this subject. (the images were png files). I notice also in this video that your paths were absolute. Is this always desirable? 0 Brian Stewart April 25, 2013 17:47 Thanks again, Kay! Keep the feedback coming! I'll address your questions below: The paths in the "Base Objects Paths" list are absolute because that is configured per system (somewhat like an environment variable). The paths to images in Image objects should always be relative, though, so your design is portable. As for best practices. I like to create an "images" folder one level down from the .dsn file where I store all the images for a given model/project. If your question is best practices for the base object paths, then I might suggest creating your own folder for your custom base objects (and maybe even still having an /images folder for those base object dsn file images), then add that custom base object path to your Base Object Path list in Altia Design. Does that answer your questions? 0 Prasanna Nandaragi April 30, 2013 05:56 awesome! 0 Brian Stewart April 30, 2013 17:27 Thanks Prassana! I appreciate the feedback and the helpful vote!
