Fly button disabled in navigation bar

[dyp4f]

Hi all.
I cannot enable the “fly mode” in 3d view.
In navigation bar, the “fly” button is grayed out (disabled)
Does anybody know how to fix it ?     
(I have Revit 2020.2.0.48)

Hi i think you are on plan or elevation (2d screen). Using Walk or Fly Mode Walk and Fly modes can only be used in a perspective projection (a camera view).

Hi, Kon Asim!

Fly mode works in perspective view mode. Click with rmb on view cube and select Perspective. After that you can use fly mode. Just clik on button wich looks like a paper airplane on right panel.

Yes, you are correct Bora Akin. I was in 3d Orthographic view and not in Perspective.

Thanks.
