extract an Ortho Photo

hello, I want to know how to set up a plan to export an ortho photo. For example: I have a facade, and I want to define the exact plan to export an ortho photo, other software allow you to set the floor with three points, it is possible?
why the ortho photo function is not activated? what are the steps?
I’m talking about the function ortho photo and not ortho projection.
can someone help me?
thank you

Hi mattia
you need to set a RECONSTRUCTION REGION and then set the desired side for an ORTHO PROJECTION.
For now it is not possible to define the projection by control points.

I’m talking about the function ortho photo and not ortho projection.

you need to calculate the ORTHO PROJECTION, and as a result you get an ORTHO IMAGE…
