Phasing and Pipe filters

[glenwalson7986]

I've run into an issue where, when using the phasing and the graphic overrides for Demo work, don't show when using the filters to change the look of a certain type of pipe. The filters settings show up, but not that it should be shown as demo. Edited by: glenwalson7986 on Aug 25, 2009 5:55 PM

How are your filters defined? In 2010 (perhaps before?), if the pipe is Demo, it is not associated with a System, and thus has an Undefined System type and an empty System Name. Thus, assuming you are filtering pipes to show different systems (based on the name of the system, as per http://inside-the-system.typepad.com/my_weblog/2009/01/create-any-pipe-system-in-revit-mep.html ), you could setup your filters such that pipes with an empty name or Undefined System Type are not selected by any of the filters you are using to override the graphics of the pipe.
