Here’s one that really got me in a quandary; hope one of you Revit brainiacs can help me figure it out.
Why is a Masking Region that behind the Cut View obscuring elements in front of the Cut View?
Here’s the scenario: I’ve got a Window family with 2 Masking Regions sketched on the stock “Right” and “Left” Work Planes. Inset from each of these two Work Planes is another named Work Plane on which I have sketched line work (Model Lines or Symbolic Lines; doesn’t matter) that will display in front of the Masking Region (in cut view). But the problem is that the Masking Region that is behind the cut view hides this line work that is in front of the cut view. If I remove the Masking Region behind the view, the line work in front of view displays accurately. What gives? I’ve replicated this issue on two workstations with recreated families. Is there a “one limit rule” on the number of Masking Regions you can have in a single family?

What is it that I'm suppose to gleen from this information. I am not speaking about masking region hieracrchy related to what's seen in front of the veiw, I'm talking about masking regions BEHIND the view hiding elements IN FRONT of the view - in the direction you're looking.

DID YOU READ? Obviously NOT!
"..You can specify the following properties for masking regions in model families:.."
"..Where the masking region is drawn. This is controlled by the Draw in Foreground parameter. When this parameter is selected, the masking region is drawn at the detail plane of the view (the plane that is closest to you as you look at the view). When this option is not selected, the masking region is drawn on the work plane on which it was sketched..."
Masking regions when added directly to a view have no front/back - they are always front except for other annotative elements. But within a family - they are special and can be like annotative or they can be on a specific plane and thus are not necessarily front.

First of all, I appreciate your contribution, WWHub. You have inspired me many a time over the years. What I don’t appreciate is your rudeness. I HAVE read this and am very conversant with it. But you are flatly wrong that Masking Regions have no front and back. A Masking Region CAN be associated a Work Plane simply by sketching it the Masking Region on a named Work Plane and deselecting “Draw in Foreground”. Still, again I reiterate: this is NOT my issue. A Masking Region on a Work Plane BEHIND THE VIEW is obscuring elements IN THE VIEW (e.g. I’m looking at my hand in front of my face, but I can’t see it because the back of my head is in the way). Get it?

Please post the family.
Your description is hard to follow ... I believe you are only talking about masking regions in a family - correct? You also talk about "... the Masking Region that is behind the cut view hides this line work that is in front of the cut view.... What does this mean? Within a project view, behind to me means "below" and in front means above. However there is no "above/behind" for project 2D linework (it is all ON the view detail plane which is basically the cut plane) but if it is model lines or lines in the family you should have said so.
Sorry, in my post, I left out "...within the project..." Masking regions when added directly to a view have no front/back - they are always front except for other annotative elements..." So, please show where within the project (not family) you can draw a masking region on a plane other than the detail plane.
PS - When you say window, I am assuming a window category family - not a window drawn in a non-cuttable family.
Also (although I doubt this will affect anything) - No underlay is on.

Hopefully the attached rvt file will clarify the confusion.

T.W.I.M.C.: When you open the rvt file I've uploaded, best to start with the "Left" Section View. The "North" Elevation View provides cross-reference information to notes in "Left" Section View. I look forward to your feedback. Thank you.

What add-ins dol you have installed? When I opened your project in 2016, all seemed OK but as soon as I wanted to open that family, an installer opened up and wanted to install what it said was Revit. I had to log off the system to stop the process.
We "caught" something like this before from one of our consultants and we were never able to identify it or get rid of it. I sure hope that didn't happen again.
Sorry - I will not open your file.

That’s odd. I’m fairly certain the issue is at your end. Initially, when I uploaded file to your site, I tried to open it directly from RevitCity. But It opened a screen of gobbly-gook instead.
The file itself is nothing special or elaborate. One OOTB Window Family (with detail line work, a couple of Masking Regions and 1 Wall Opening) loaded into a fresh Project Template containing 1 Basic Wall. No add-ons.
I’ve uploaded the file to Revit Forum and to AUGI as well. Perhaps, you can download it from there.
I appreciate your participation in this thread, WWHub. Thanks.

See if this file works. I've uploaded it from the Desktop location on a different workstation.

I'm sure it's the sme file and I will not open. The "gobbly-gook" happens because you tried a direct open. You have to right click and do a "save target as".

WWHub: Thought you'd get a chuckle out of this cartoon...
Cheers
