Parts of wall disappear in 3D

Hi! I have drawn a wall, and when I go to the 3D tab, the wall appears broken into parts. When I click on the wall, I can "see" the outline of the wall, but the parts in the middle are missing. I do not have any windows or doors placed; I simply created one wall.

Hi @adrianasofiasm_

It's hard to say with the information provided, but perhaps you used an opening or even a hidden element with a construction element that has a higher priority than the wall. Try displaying all layers, even hidden ones, to see if there's anything there.

If you are super away from the Project Origin, that could create some issues like this as well.

Try to make all Layers visible and display them in 3D. Hopefully, you will see the element that is intersecting with the Wall automatically and causes this result.

If an element on a hidden layer is indeed the cause, you can create a Layer Combination and make sure that the Layer Intersection Combination Number of the other element's layer in that Layer Combination is zero (0), and apply that. That way, the hidden element will not intersect with the Wall and will not cut out part of it, even if its Building Materials have a higher Intersection Priority.

Another test is to drag a copy of that wall away by some distance or raise lower the copy in height.

If it reverts to normal, then there is another element in another hidden layer that is causing the wall to trim as others have mentioned.
