Incorrect slab section

[ekaterinarch]

Hellow!

Have anyone faced a such problem: one element (slab) on the section is cutted wrong? It looks like the slab has completely different geometry and has no layers. Look at my screens. 

There is a plan with 2 sections. 7th is false, 6th is true. The same view template. No element's overrides. Direction doesn't matter. When I try to do the new section at this place I have the same picture. But! If I switch view detalization to "coarse" it appears right! (I attached two 7th section with different detalization to compare the geometry)

The problem didn't appeared immediately... At the beginning of model it looked good.

Any ideas?

(To delete and remodel this floor I can myself, but it is not good way)

Hello, can you upload the model so we can see the problem better?

Section 6 and 7 are not in the same Direction! One pointing SOuth the other Pointing North!

I see nothing wrong with your slab...not sure If I am missing something (Maybe you could highlight exactly the foul spot) Other than that, one section (6) CUT Through the slab while the 2nd section (7) would be showing mostly a  Projection because it is passing through  FLoor Openings (Void)

Break/split  the section line and shift it to cut through thte slab and both 6 & / will look the same

Then why it has another form in coarse?

And there is another slab with holes, and it cutted correctly.

@ekaterinarch 

Because floor elements has a a Graphics override when in coarse fill (same for walls)

[ekaterinarch]

It has no overrides. Now I colored it red. 

But in medium it has not even cut lines

It is interesting that I copied my slabs to the new project to post, and in the new file the sections are correct like it was at the beginning of modeling/

I suppose some of joined elements give this effect. But is any quantitative restrictions of joined objects?

[ekaterinarch]

I have found the reason. It ws one of the joined walls. I re-switched the order and the slab appeared right. Something disappointing... At least I know now(
