Visibility Below Cut Plane In RCP

Visibility Below Cut Plane In RCP

We very often need to see things that are below the cut plan on an RCP, such as furniture, parking lines, sidewalks, etc. Right now, I'm working in a lighting RCP, but I need to see a pool. However there currently is no way to see anything below the cut plane in RCP.

Please find some way to modify RCP View Range properties to allow us to see below the cut plane.

if you are in the ceiling plan you can add an underlay of the floor plan to see the objects below the ceiling cut plane

Unless I'm missing something, when you change the Underlay Orientation to "Look Down", it Looks Down for everything, so then you can't see your ceilings.

In the ceiling view i'm looking at the ceiling grid and other objects are still visible and the objects below the cut plan are grayed out but visible. and they are not blocking out the ceiling objects.

@Mathew.a.MIller, what version of Revit are you working in, because that's just not how Underlay is working for me.

 

Also, that won't help for instance when you have lights below the cut plan and you want to see them in RCP. I am currently working on a project that actually have lights flush in the floor. I can't move my cutplane down so their visible or my walls won't be visible. So I'm left with using plan regions...

@scbunker Could you find any solution to your question? I would like to know. I am having trouble doing that, too.

I don't believe underlay settings work as @Mathew.a.MIller is suggesting when you're working with a linked architectural file.  Unless you're working for a one-stop-shop firm, the common workflow for light fixture layouts or other ceiling hosted devices would be to work in a separate model from the architect, with the architectural file linked in for reference.

Here's a similar idea that's been around since 2016 and received a lot of support.  The issue is really that you lose some key functionality when working with linked files.  This should not be the case and desperately needs to be addressed.

@Nate.Ritta I'm using Revit 2020 to look at a ceiling plan, and when I turn on the underlay to look up I see all of the elements at are on the floor, Doors windows etc that are not visible in the ceiling plan. since I am an Architect and in the Architectural model it works the way I would imagine it to. But when I went to the MEP model I see the issue you are discussing. Until Autodesk fixes this apparent bug with linked files the only work around I can see to to change the cut plane to a minimal number.

To update this thread with  how I have worked around this:  I create an 'underlay' floor plan that only shows the architectural elements I need to see and place it on the sheet. Then I place the RCP on top of that and align the views. Then I work on the plan by activating the view on the sheet so I can see the underlay while working.

 

If you use this workaround, it important to place the underlay first since there is no function to adjust the draw order of the views after placement.

It would be great if the underlay could have a view template applied, what I need to see varies from project to project. Currently 2 views is the most flexible option.
