Most families show annotations that are dashed lines to indicate that they will be removed at the demo, but a few (data, ceiling-mtd exit signs, etc.) are solid lines. Any ideas on resolving this? I have looked into the families annotations and cannot find where to edit its phased symbol. We currently have the graphics configuration shown below.
This seems to be more a matter of the line segments being too small for the Line Pattern to be applied (which is just like the way it is in AutoCAD). The only practical solution (if this is an unacceptable problem) would be to use a finer Line Pattern for your demo overrides.
As a test, create a copy of your combo data/voice Family and edit the embedded Generic Annotation and double its size. Load it into a Project and make it demo to see if it inherits the correct Line Pattern.
