Orthophoto generation with Descartes

Hi.

I'll try to generate an orthophoto of a prospect from my 3d mesh.

I see that there is the possibility with Bentley Descartes CONNECT Edition to generate orthophotos in any orientation directly from reality meshes created with ContextCapture, by GENERATING A SECTION of a view and using MERGE TOOL to export my orthophoto.

I attach my 3MX mesh generated with Context Capture, but I can't create a section.

Any solution?

Thank's
