Profile Family Line Styles

[ndsmaug]

I have modeled a composite structural floor slab using the Structural Deck option for the function of my metal decking.  It allows me to then select which decking profile family I want to see in my sections.  It's working great, except I noticed that the top line of the decking profile (if looking at it in section cutting parallel to the decking) is associated to a line style Thin Lines.  This is a problem because we've changed the object style settings in our project template for Thin Lines to look like something that I don't want for this profile.  The strange thing is, if cutting perpendicular to the decking so that you see the ribs in elevation, this Thin Line is not visible.   (See my shots below for both cuts)

How can I get this decking profile to NOT use Thin Lines as it's line style when it's used in my project?  I have read if I create a line style in my project that is the same name as the line style used in the profile family, (in the case of a profile family you only have two options for lines and they are Profile and <Invisible>), I can then adjust the object styles, but I have not been able to make this work.  Every time I load this type of family, the lines default to THIN LINES.  If I copy the linework from the family directly into my project as a test, it turns those lines into Thin Lines instead of keeping them Profile even though I now have a linestyle named Profile in my project identical to that in the family.  

Can someone offer some help? 

Thank you!

I don't see a way to change the line type that Revit is using for that...a workaround would be to override the graphics of thin lines in that view.  I would recommend that you create your own "thin line" line type for your custom requirements and leave the out of the box "thin line" at the default.

When you're cutting parallel to the decking the top and bottom lines are being cut through while the line at the top of the flute is "beyond" the assumed cut plane. Revit programmers coded that line "beyond" to use a lighter lineweight (by mapping it's graphics to use the default Thin Lines) while the topmost line and the lowest most line are mapped to heavier line weights (which are controlled by the object display settings of the floor) to differentiate between what is being cut and what is not.

What you will also find in this particular example is that there are two different values in the visibility graphics that affect that particular intermediate line. There is the value of "Thin Lines" (as a subcategory of Lines) and there is also the "Common Edges" as a subcategory of floors. The two different values play against each other.

It's hard coded as far as I know.

I guess they never figured that someone might redefine their version of Thin Lines to be a heavier line and create such an issue... but even that doesn't explain why there are actually two controls for the same line.

Even if you get something figured out as a work around with this additional info please do not mark this as a solution... the software engineers need to figure out how to give us more control of things such as this so we can do what we need to do to get our drawings to look the way we need them to look.

Thanks guys for the feedback about how Revit is treating this condition.  This is some good info.  If we're not allowed the flexibility within the software to change this, I think the unfortunate answer for me is to re-evaluate our use of Thin Lines, or build into our section view templates a new override for that Revit default line type.  

Thanks!
