Hi everyone,  
does someone can explain me how to generate correctly a orthoplane.

I explain:  
I make a surface to align the box, Then I optimize box and after I generate the orthoplane  
Everytime I try to generate it, I have issues like this one (that you can see with the picture linked here)  
pictures have been made with a drone face to the wall in oblique position (not nadir)

Hi @hugues_calderero,

Our algorithm is not optimal in using oblique images to generate orthoplan. The best would be to have orthogonal images to the façade you want to make.

This is also explained in this topic:

> Hi Larry, Thanks for sharing your issues and workaround that you have experienced with our software. I would like to mention that sometimes the generation of an orthoplan is not so straight forward to reconstruct especially as the mosaic editor is not available for this output. Some users tricked the software in order to have their orthoplan horizontal so the software considers it as a map and then they were able to use the mosaic editor. I would like to add that for orthoplan, our algorithm…

Good luck,  
Best

Hi Joan,  
thank you for sharing toturial.

Hi Marco,

thank you for your feedback.  
I tried so many times to generate orthoplane in lots of projets with that kind of issues.  
Know, I understand  
I will fly djfferently

Sincerely

Hugues,
