Draw a Shaft, add Symbolic Lines to represent the duct inside and the typical "X". Create a Detail View of this and not only do the Symbolic Lines not show up but neither do the Shaft lines... hmmm.
Is this how it's supposed to be? Is there something I'm not doing? I can get them to appear in a Floor Plan view but we've already got everything called out with Detail Views and placed on sheets.
Thoughts? Ideas?
