Problems in showing wall on slope mes terrains

[iggiv]

Hi everyone, I’m running into a technical issue while designing a multi-residential project in Archicad 29 and would appreciate any suggestions.

I’m using modules for repeating apartment units and creating two towers with different layouts. The site has a significant slope (about 4 meters difference from north to south) and is modeled with a mesh set at 12 m above sea level.

When placing the modules for the towers, some walls do not display correctly in the floor plan. They either disappear or do not show as cut walls.

I suspect it’s related to the varying story levels relative to project zero due to the sloping terrain.

I have already tried:

• Adjusting the Floor Plan Cut Plane

• Changing the Wall Floor Plan Display to Symbolic Cut

But the walls still don’t appear correctly.

Has anyone experienced this issue when using modules on sloped sites with different story elevations?
Are there recommended settings for module placement, story references, or wall display settings that could resolve this?

Any ideas would be greatly appreciated.

Thanks everyone for the suggestions.

Since I have my final construction permit presentation this Monday and needed the wall thicknesses to display correctly on the site plan, I ended up using a different approach.

Instead of continuing to troubleshoot the wall display within the module instances, I placed an externally linked view/layout of the tower level onto the site plan layout. This allowed all wall thicknesses and cut representations to display correctly in the final documentation.

The good news is that the modules remain fully functional in the model, and everything continues to display correctly in 3D views, sections, and elevations. The issue only affected the floor plan representation of walls at the different site/story elevations, likely related to how the walls were being interpreted relative to the various story levels on the sloped site.

While this doesn't identify the exact root cause, it provided a reliable solution for producing the permit drawings on time.

If I discover the underlying setting causing the wall display issue, I'll post another update.

Thanks again for all the help.
