Underlay not working in linked file

[linkboy]

I made a file struct.rvt with two objects above level 1 view range. I can underlay and check the structure above, like a ceiling plan view. Picture below:

However, linked file seems ignore underlay objects in the host file view. 

 (struct.rvt was linked into Arch.rvt, the image below is from the host file, Arch.rvt)

Can we possibly get a underlay view from a linked file?

In your V/G menu, in the Revit Links tab, check the "Underlay" option for your link. Then it will show up as an underlay.

It works for looking down. In the sample file I posted, I have "beams" above level 1 view range. If you check off underlay link in host file, the beams won't show. Can you send a screen shot showing beams from host files view?

I'm unable to make it work, unfortunately. It seems only certain family categories in linked views are visible as part of an underlay. The closest workaround I can think of is to make a plan region which will show the beams, then override their category in the Link's V/G menu. But I'm aware this is not what you are trying to accomplish.

It looks like there is an idea for this which has gotten quite a bit of support. You can vote for it here:

The word Underlay is used in two features, different from each other. The "first" Underlay" is that feature that you activated in the nested model, which is for projecting edges of elements that are in another level, to the current level.

The second "Underlay" is that feature that you see in the Visibility Graphics window > Revit Links > to the right side of "Halftone". That Underlay is to have the ability to adjust the brightness or tone of the lines of a linked model. Instead of of just a fixed half tone. If you apply that Underlay, you can adjust the tone of linked models in Manage > Additional Settings.

The first Underlay feature does not work with linked models, only in the same model.

Solution: go back to the nested link. Go for example to "Level 1" plan view. Activate Underlay, with base at Level 1, up to Level 2, looking up. You will see the projection of beams or edges of slabs. Then use the Linework tool > Overhead line style, and click on the edges that you want to see. Then turn off the Underlay feature of the view.

Now go back to the host model. Go to Level 1. Go to VG > Revit Links > select the nested link > By Linked View > Level 1.

Now you will see in the Level 1 view of the host model the projected lines of the Level 1 view of the linked file.

I had this same problem and I solved it by changing the view range bottom and view depth to the level below and then set the plan to wireframe. In my example, we just needed to turn it on to coordinate something and then we set it back to normal.

Hi,

Any other options,

I am using a revit link for my electrical project but I can't see the projections of the roof on my floor plans,

Any advise? 

Thanks!

I tried all of these things, including editing the linked model to show the underlay, but nothing worked. I ultimately went back to my original model and went to the floor I want to see, created an overhead line on the outline of my floor, and copied/pasted aligned to the views I wanted to see it at.
