Duct lineweight vs fitting lineweight

[pteague]

I'm having an issue where the duct lineweights and fitting lineweights aren't matching.  I've checked everything I know to check (VG overrides, global object styles, system specific graphic overrides, view range settings, filters).

Any thoughts?

You seem to have checked the obvious things.

Is this every duct fitting or all of them? Silly question, but are you using view templates? If so, is the view template locked to use the correct settings? That's the only thing I can think of if you've looked at filters, VG, Object Styles...

1. Change line thickness of DUCT and DUCT FITTINGS on Object style dialog. This will be applied to all not overridden views.

Or

2. Override graphic settings of a view by changing the thickness of DUCT and DUCT FITTINGS in the current view. This is applied only for the current view.

I may have found a major clue, and possibly a real problem with Revit's ability to do plan regions in ceiling plans.

We have a plan region set up in this area. The main view range settings are cut at 7.5', top at 11.5' and depth unlimited. The plan region is cut at 7.5', depth at 25.5', and depth at 25.5'. The plan region affects the lineweight of only the fittings and not the duct. The duct lineweight is only controlled by the main view range.

So the duct lineweight is being shown in the <BEYOND> line override because it is above the top elevation for the view range.

This seems to be a major inconsistency in Revit's handling of plan regions in ceiling plans.

Sorry, my last post was useless, didn't read you carefully

I had had this issue, and I solved it. Also, I tried to model your problem, and for me it seems, that everythong is fine (ceiling plan with plan regions with different view ranges).

Could you model this problem again in an empty rvt-file and upload it?

Here's an exact replication of the issue from an empty project.

I have set the <BEYOND> linetype to be red to highlight the issue.  Duct shows as red (beyond), fittings show as black (normal).

Nice detective work. Seems like you found an issue with plan regions then. I've had similar issues with pipework and plan regions (where they don't show drop / rise correctly). 

As a workaround you could make a filter for Ducts and apply the lineweight you require for ducts, as filters should take precendence. Silly workaround I know, and it may not work depending how you have your views set up.

Hello, dear,

please, check your view ranges.

Your duct is placed on 9' 0''.

The upper view range is 8' 0''. If you set the upper view range higher, that the center-line of your duct-works (for example, 9' 00''), I guess, you will get correct linetypes. Please, try this and let us know, if this helps (I succeeded in your duct beyond.rvt ‏).

I know that my view range is lower than the duct, but the plan region should be overriding the view range settings, and it does for the duct fittings but not for the duct.

Just wanted to let you know that it is one of the known major issue with MEP family system and plan regions from long time ago, it is still under investigation to find a fix but for now you need to use graphic override and filters as alternative solutions.

I will keep you posted in case i get any updates on that.

Some related issues such as Rise/Drop Symbol vs. Plan region is been fixed for the upcoming release (2017)

Thanks for the update.
