Showing hidden center lines in ducts going down

[silviaberian]

Hello,

how can i show the center lines in the duct that goes downwards hidden?  I do have the round part of the duct that is hidden showing that way but the centerlines show as cont. lines.  Does anybody have a solution to this?

Thanks

Silvia

I believe that is a block. Poke around in the rise and drop styles under HVAC Objects in the Styles manager.

The centerpoint that represents where the center line goes down in a rise-drop block is mapped to a non-plot layer.  It is necessary to be able to select vertical segments in a selection set.  It also is handy if you need to Osnap to the center.  It should not plot unless someone changes the layer inside the rise-drop block itself.
