Extrange topography behavior when cutted with section box

[Francisco_Céspedes]

Hi, I´m a senior architect and with 16 years experience using revit and this is the first tima I saw this weird issue with topography. When I apply a section box to it, extrange caothic lines appeared anf fillerd all the image, and I can´t find a solution to hide them. I have tried all I know about it without results. I cant´t use those images and 3D views in the project so is a serious issue. The project is an aerial tramway in a hill, so topography and the stations locations in the hill is a mayor issue, so the correct site represntation is a key feature that can´t fail.
Any idea of waht in not workinh here?

Hola Francisco!

What is likely happening is that you have overlapping model geometry with the topography. If you could share a screenshot or two showing what you see, it'd help confirm if this is the case and I can then suggest some fixes.

Post a screenshot of what you are seeing.

Have you splitted topo or created subregions?
