When plotting from the IPLOT dialog, the following message appears: "The design file has changed since it was last saved. These changes will not be reflected in the plot unless the file is saved now. Do you want to save?" What causes this message to appear?
If you enter a workspace name that is different than the workspace you are displaying with, you will get prompted with this message. Typically, IPLOT uses the current session of MicroStation that you are displaying to process the plot along with the currently displayed workspace. When a user enters a workspace name that is different than the currently displayed workspace, IPLOT runs the command line in the background using the new workspace. To make sure that the design hasbeen updated, you are prompted to save the file. If you don't want to get prompted, make sure you use the same workspace that you display with when plotting.
