Only Duct fittings are visible in Ceiling plan Region

[stingers80-cgarchitect]

I have this issue where only Ducts fittings are visible in Ceiling plan.

I am using a plan region for a part of plan and with whatever value I try in plan region I can only see the duct fittings and not the ducts. However, if I change the view range of the the whole view, ducts will show up in the plan region as well.

Is this a bug? As i understand plan regions are independent of the view range of the view they are in.

I'm on Revit 2022.1 and Mechanical drawing is Linked.

Thanks

Is the Link displayed BY LINKED VIEW or BY HOST VIEW?  

...wait. Are you saying that they are visible in the same view WITHOUT a Plan Region, but invisible when Plan Region is applied? If so, I'd looked again at View Range Settings.  Ceiling View Range is backwards from Plan View Range.

A plan region needs to capture the entire element in order to show it.  If your plan region only captures a portion of a duct then the duct won't show.

@barthbradley  It is linked by host.

I have a plan region in a ceiling plan.

In the Plan region I can't see the duct(only fittings). However I play with height values of view range , they won't show up.

But When I change 'view Range' of the ceiling plan, ducts show up inside the plan region which is weird because I assumed plan regions in a view are independent of the view's view range.

this makes the rest of the view unusable because other elements are visible that I don't need.

Check the name of the LEVEL listed in the Plan Region's View Range. Is it the same as the name of the LEVEL shown in the View's View Range? I'm thinking not.  

...ha! I'm still a little confused by your description. I've read it 3 times and understood it differently each time. Can you just post the File?

I think it captures the whole duct. I'm just not sure why elements become visible in 'Plan region' when I change the view range of parent view

This appears to be a "known issue"...

The file is 400MB.

So here are screenshots.

1- this is the view range of the main view (not the plan region)

2- This is what happens when I change the view range.

notice the ducts inside the 'plan region' appear.

oh...back from 2016.

thanks

....and 2018.  

...what about using a Scope Box? That work "around"?

You could join this guy's party...

Can you share a screenshot showing the duct and the plan region?

[ToanDN]

What about leaving the view range alone to show the ducts, and adding plan regions and changing their cut plane to show other stuff?

I will test showing ducts inside a plan region when I can get a hold of Revit.

[ToanDN]

Tested in Revit 2022 and Ducts don't show in Plan Region.  Fitting and Duct Insulation do show.

[barthbradley]

Another workaround might be to display the Link By Linked View.  

...that wouldn't affect the Parent View Range.

The screenshot I sent shows plan region and ducts. (the green dashed lines is plan region)

my biggest problem is that when those ducts are visible, I have to hide some stuff in the rest of plan.
