Correct display of roofs

Anonymous — Tue, 23 May 2023 12:18:02 GMT

See attached. I have two roofs, a main and a side roof. The side roof is overframed onto the main roof, but a piece of it goes under the main roof. I want this to show correctly in plan. If I adjust the display order, it either shows the entire side roof above the main, or it hides it below.

I posted this a while ago, but I can't seem to make the old method work. http://archicad-talk.graphisoft.com/viewtopic.php?t=38191&highlight=

You may be looking for a 3D document approach, as demonstrated here: https://www.youtube.com/watch?v=5hVsyCu6vFw

I need this to show accurately on all my floor plans. I don't think a 3D document will work here.

Hi Steven, maybe this will works:

1. Select the two roof planes
2. Right mouse click>Connect>Merge Elements

Zoltan,

Unfortunately, no.

Steven:

Here are two options. First select the over-framed roof, right-click and select Connect > Trim Elements to Roof/Shell, click the main roof, and then click on the part of the over-framed roof you want to remain. The main roof will cut away the over-framed roof. Then:
1. For the main roof, Roof Settings > Model > Trimming Body > Pivot Lines down (rather than Contours down) will trim the over-framed roof at the Pivot Line, not the edge. This will work if the Pivot Line is where the over-framed roof needs to end.
2. If adjusting the Pivot Line creates problems elsewhere in the model, then add another over-framed roof piece under the main roof, select the 2 over-framed roofs, right-click > Connect > Merge Elements.

David,

Thanks for the reply. I tried it but it's still not working. I understand how to trim the roof, but my problem is I want it to look correct in 2D view on floor plans. This is what it still looks like after trying your method.

This is how I want it to look, with the portion of the side roof that is under the main roof hidden by the main roof.

Maybe this can't be done? As a workaround, I could use 2D fills and lines to make it happen.

Split the 'lower' roof into two pieces, set one above the main roof and one below it.

You need to cut the upper roof like I did in my picture. You can see where I crudely line hashed the lower roofs where they are under the upper roof. And the upper roof is first in the display order. That way it allows the display of the roof lower in the display order.

I don't think the roofs are Connected, because the Display Order does not change the display of the the two roofs relative to each other. Make sure the two roofs use the same Floor Plan display (your main roof looks like Projected with Overhead). It works here, see attached screen shot. In the 3D view the pink tones are the Trimming Bodies.

Check the 'Legacy' setting you have for the roof display - OPTIONS menu > Project Preferences > Legacy.

You may have the "Symbolic Display' for 14 and before turned on.
