Site display in Section / Elevations

archislave — Thu, 25 May 2023 15:13:54 GMT

I modeled the site using the mesh tool, although it is not 100% accurate. When I cut the section the cut line of the mesh runs through the foundation wall. What is the best way to deal with this?

Maybe turn off the mesh and draw a cover fill? ... Defeats BIM.

I would do a solid element operation and subtract the footing / foundation from the site mesh.

And if you need a basement cut out, I would do a solid element operation and do subtraction with upwards extrusion. Someone correct me if I am wrong on this.

Do you have the fill background pen set to zero in the wall settings ?
If you change this to pen 91 and send the mesh display order to the back
this should fix the problem.

It strange, but canging the background pen to 91 and bringing to front have no effect. I guess a solid element operation is necessary.

That is strange.
I just tested this in AC 10 and it worked.
My mesh has the fill background pen set to 91 as well.
This problem does not occur in AC 9 or AC 8.1.
I just tested it in AC 9 and AC 8.1.
Graphisoft must have changed the section/elevation
default display order for meshes.
I notice that your footing has a similar problem.
Is it's fill background pen set to zero ?

I am also unable to get a floor truss to show when I move it within the floor slab plane. The floor slab background is transparent and the truss is move to the front.

I believe what you are describing is normal behavior for AC
and always has been. The way to see the truss when it is
buried inside something else in section/elevation
is to move the section marker so that it cuts through the truss.

The background FILL is transparent, but the slab is still a solid object. It's like trying to see the rebar inside concrete after it's poured... It's part of why I stopped modeling floors as true solids and tend towards sheathing only.

Keep discussing your techniques. I am learning a lot.

I have changed over to representing the roof as a Sheathing/Roofing combination and Modeling a Fascia, but I have not "moved" to only representing the floor as sheathing. I have desired to.

Tom, are your walls represented as from floor-to-floor, if so, how are you representing the floor rim in 3D?

For now I am using composites as my floor slabs. Most of the composites represent the sheathing, joist depth and insulation. For representing TJI joist I add a few extra lines in the composite to depict the flanges.

I even have a composite that also represents a 1/2" Gyp-board (Sheetrock) layer below joist. This is nice to represent the sheetrock layer, but the true bottom of the floor slab with reference to the wall is actually at the bottom of the joist not the bottom of sheetrock.

Another reason why I do Not use the Composites with the Gyp-board below the floor joist slab.

Extra Line on Exterior elevation.

The problem is represented better with a Vertical instead of Horizontal Fill pattern.

Can you show me how you do this, representing the roof as sheathing and modeling the fascia?

Seiss, see private message that I sent.

Can you show me too? Maybe all of us since this goes against what we have been taught but is actually closer to real construction!
