Best practice for showing walls under roofs?

[KAPAArch]

I'm working on a roof plan and have hit a classic conundrum that I imagine many of you have run into.

I need to show the bearing walls underneath the roof to dimension the overhang distance, but I also want to keep the roof's material surface pattern (shingles) visible. I am struggling to find a clean, efficient solution that doesn't involve countless clicks or graphical conflicts.

Current Roof Plan:

Intended Result (for this small example only using the linework tool solution):

Here is what I have tried or had suggested to me so far, and why they aren't quite working for this use case:

1. Linework Tool: I know I can use the Linework tool to set the wall edges to <Hidden>, which pushes them through the roof. However, I have 25+ walls to do this for, and the lines often break or become inconsistent where the walls attach to the roof. It feels highly inefficient for a project of this size.
2. Plan Views: I’ve looked into using Plan Regions, but they must be closed loops and cannot overlap. I would have to create a separate, carefully sketched region for almost every wall orientation on the building, which gets messy. I also don't want to actually cut the roof; I just want the walls visible beneath it.
3. Visibility/Graphics (V/G) Overrides: I tried setting the wall Projection/Cut lines to dashed/hidden in V/G, but it doesn't push the wall outlines through the roof's surface. This would be the ideal, most automated solution, but it simply doesn't yield the intended result.
4. Overlaying Views on a Sheet: It was suggested that I create two separate plans, one showing only the walls (Hidden Line) and one showing the roof(s). and then to stack them directly on top of each other on the sheet. I’m hesitant to do this as it feels like a heavy-handed workaround that abuses the sheet system and makes future view management a headache.

Just to reiterate, my exact goals are:

1. The roof's shingle surface pattern remains visible.
2. The walls supporting the roof are visible through the roof (preferably with hidden/dashed lines).
3. The wall lines are dimension-able so I can document the overhang distance.
4. The solution is associative, if a wall moves or is deleted, the lines update automatically (no faking it with detail lines).

Drop the view range down to the lower level, and use visibility/graphic overrides and filters to hide everything other than those bearing walls. 

If you use a template (hopefully you do) save these settings into a default roof plan view template so you can easily reuse it in the future. 

[KAPAArch]

Drop the cut plane plane, the bottom or the view depth level to below the roofs? If I hide everything other than the walls won't that hide the roofs as well?

[mhiserZFHXS]

Well don't hide the roof... I assumed that went without saying... 

And not the cut plane. Just the bottom of the view range. 

[KAPAArch]

Changing the view range does not show the underlying walls, see my example. The roof is assigned to level 2.

Sorry, set it to wire frame. Or use a filter / graphic override to make the roof transparent. 

[Zach_RossT2ULN]

Have you tried using an underlay?

[KAPAArch]

To no avail

[KAPAArch]

will this not remove the material pattern of the roof? This is one of my requirements in my original post.

Wireframe, however might be the solution. Give me a moment to review.

[Zach_RossT2ULN · Accepted solution]

sorry, you have to set the view at level 1 and show the roof using the underlay. a view template can then show the wall cutlines as hidden. Feels backwards but will get the results you're looking for:

[KAPAArch]

I find this solution to be rather decent, my only issues being that now all interior walls on that level are also visible meaning unless i properly set the wall function property of the walls and hide based on that I would have to manually hide them. I also cannot easily select or edit the roofs meaning a working roof plan would probably have to be created.

[KAPAArch]

I did not think wireframe would have kept the elements surface pattern, now i see that it does. Still some kinks I might have to work around, but I would say this is close enough to what I wanted. Thank you for your time in finding this solution.

[Zach_RossT2ULN]

selecting and editing the roof will work normally if you have "select underlay elements" turned on:

I'm not sure why you're against setting the function of your wall types since this can be used in view templates for this roof plan and other plans/views that only need interior or exterior walls shown.

[KAPAArch]

I imagine I keep the underlay selection off because of the typical mistake in selecting an underlay element instead of one on the current level, but you are correct. Also I don't disagree that setting wall function for each type really is not hard to do at all. Because of this I will mark yours as a solution as well, I really appreciate the help.

@KAPAArchBelow is one of the widely used methods to set the view as required:
1. Bearing Walls should be modelled using "Structure Tab -> Wall"
2. In the Floor plan or Structural plan, set "View settings -> Discipline -> Structural"

 

[KAPAArch]

I never really messed around with view disciplines, after this I will definitely keep this in mind a lot more. I would say this is the best solution to date.

[Mike.FORM]

Use the "Show Hidden Lines" command in the View tab. You will need to make sure the "bottom" of your view range (not view depth) cuts through the top of the wall.

 @KAPAArch your image in message 8 of this thread, since its a roof plan, shouldn't your underlay be looking down?

[KAPAArch]

I was responding to another user's recommendation for a solution showing that it did not work.
