I'm working with ACA 2019 and new to projects navigator. I have created a construct of the external walls and one of the internal partitions. The first floor partitions construct references the external walls construct. When I create a view and add the first floor partitions to the view the external walls are not displayed. Below are two screen shots one of the first floor partitions construct and one of the view. Is there a way to turn on the xref Building Shell walls in the view?

Add both Constructs to your View drawing (at the time of creation, or afterwards). Typically, Constructs externally referenced into other Constructs (for reference purposes) are brought in as Overlays, which do not carry along when the parent Construct is externally referenced in another file, such as a View.

This is desired behavior - it gives you control over what you get in the View file. If the Exterior Walls file was an Attached reference in the Interior Walls file, then you would have no choice but to have it come along. And, if that file were Attached to two or more other Constructs that are then needed in a View, you would get multiple nested copies of the Exterior Walls file.

You have allowed Wall Cleanup between external references in your Standard Wall Cleanup Group Definition, so, assuming that is assigned to the Walls in your image, Wall Cleanup would be possible. I cannot see where your Wall Justification Lines are from the image; I am guessing that in the area that you circled the lines do not cross, and the cleanup radius of the vertical Wall is 0.

The easiest way to enable Justification Display is to select a Wall, and then, on the Wall contextual ribbon tab, on the Cleanup panel, select the Justification Display tool. That tool will highlight when Justification Display is active and will go back to normal when inactive.

You can also use the WALLJUSTIFICATIONDISPLAYTOGGLE command, but that is a lot of typing. You can also enable the Graph Display Representation for Walls in your currently active Display Representation Set, but that is even more work than typing.

Cleanups of objects in external references can sometimes be trickier than objects that are "live" in the drawing, particularly between two external references. In your image, the "vertical" Wall only partially crosses the "horizontal" Wall. Perhaps that is good enough when one of those Walls in live, but the way external references load in and the order that objects are resolved may result in the cleanup being missed. Sometimes running the OBJRELUPDATE command and just hitting the ENTER key (to run it on all objects) can get things to resolve. Having the Walls' Justification Lines touch or cross should result in proper cleanup.

Maybe Renovation Mode has something to do with it? I was curious is something was cooked in one of my constructs so I created three new constructs and a view and everything cleaned up fine. Then I switched one of the new constructs to reno mode and boom the clean up stopped working in the view. The only problem is I don't know how to fix this so the walls clean up across the xrefs.

That may be it. When you initiate Renovation Mode, all items already drawn are considered to be Existing. Among other things, those now Existing Walls will be assigned to a differently-named Wall Cleanup Group, thus preventing cleanup with Walls in other Wall Cleanup Groups.

Not 100% sure what is going on in the file where you are externally referencing the Building Shell Construct into the 1st Floor Partitions Construct. It looks like cleanup, but it also appears that an entirely different Display Representation Set is active. In any event, check the Wall Cleanup Group that is assigned to the Walls. They may have been all the same initially, but after starting Renovation Mode in one file, those Walls will have a different group assigned.

Okay so the issue was the wall cleanup styles. I had to add the Standard_(Existing) cleanup group to the view and reload the constructs. Now the walls cleanup as expected. It was working in the construct because both the Building Shell and First Floor Partitions constructs had the same wall cleanup groups but the view didn't have it.

In a cultural sense, both the Great Wall of China and the Trump Wall are more of mental and psychological constructs than architectural and physical constructions. Both the first emperor of China Qin Shihuang and the 21st century American president Donald Trump share an inflated personal ego, reflected and magnified on these two walls.

Grossman (2010) also testifies to the illusion of the protective sense of the Great Wall of China from trading and stock market perspective. The crisscrossed indexes and mutual funds are a proven wall-breaker.
