Solid operation on slab( plan view)

Hi

How come any solid operation effectuated on slab no not show up in plan view?
Example:
Draw a 200mm thick slab in plan view (we cal it slab A).
Then draw an other slab 300mm (slab B) intersecting slab A.
Then effectuate solid operation on the slabs an place Slab B on a unseen layer.
Look now in plan view and compare with 3D view.
Solid operation does not seem to work on slabs in plan view.

It does work on roofs though!!!
Is there anyone knowing what i do wrong? Is there any parameter i do not know?

Currently Solid Element Operations do not show in Floorplan. Boolean operations on Morphs and Trim to Roof/Shell operations will display correctly in Floorplan. It is a limitation and has been this way since SEO was introduced.

The question is what are you trying to accomplish? And maybe there is a better way with a different method.

Hi

Thank you!
Like you see on the picture.
It is a house where the second floor is smaller than the first floor.
So the slab on second floor sticks out to be a part roof on the first floor.
I am trying to do a chute on the roofs because I dont want to have a hanging gutter.
I did a SEO on the roof with a custom profile and we can se it in floorplan.
We can not se the one one effectuated on the slab.

Too bad
i guess i have to draw lines other way I will have to redraw all the roof on the first floor.

Instead of adding lines can you just leave the SEO operator showing on plan to indicate where your "chute" is? Turn that layer off in 3D views to show its effect when subtracted.

Hi there,
I think the error lies in the workflow you're using ( not bad, but it follows a different logic, the logic of free form modeling)

Try a different approach:
Keep the slab for you slab/floor up to the limits of the Envelope, then create a separate element for the Roof.
The second element - the roof - can then be done with a single Morph by "morphing" your existing roof ( so you don't loose what you already did )
If you are in a higher level of detail, then you should consider modeling it closer to what construction would be, maybe one roof for the top geometry and a slab for the soffit / ceiling?

In this way you don't have to "draft it" it will be all done with native AC elements, and the Plan representation will be correct.

Hope this helps
