I am very glad to have the "Halftone/Underlay" settings in MEP 2010 but I am still trying to figure out exactly what it's limits are.
The interface for this command seems to suggest that if you set the lineweight to "1" in the "Underlay" section then all of the lines in the underlays in your model will have a lineweight of "1". From the Revit MEP 2010 help:
In the Halftone/Underlay dialog, under Underlay, define the following settings:
Weight: Specifies the line weight for underlays. Select a value from the list.
This doesn't appear to be the case, though. Some lines in my underlay remain thicker than a "1" lineweight. For example, my Object Styles lineweight setting for "Generic Models" is "3" because I want non-underlay elements in my model that are categorized as "Generic Models" to stand out more. Even though I have "Underlay" lineweights set to "1", elements in my linked underlay that are categorized as "Generic Models" have a lineweight of "3".
I know I can do custom display settings for my links and adjust lineweights there but I thought I had left that behind me with MEP 2009. What exactly am I achieving when I set lineweights in the "Halftone/Underlay" command? Whatever lineweights I have set up in "Object Styles" seems to override this. I would rather have it be the other way around, "Halftone/Underlay" should override my "Object Styles" settings for my underlays only.
Any insight into this is appreciated.
