How to set camera FOV according to geometry in the model?
-
Hi,
Is there any way to set the camera FOV and its direction along geometric lines defined in the model? In an architectural competition, we have currently the camera view defined with only two lines. To set the camera position I am using the Position Camera tool, which is easy, but I still have to guess and eyeball the field of view. I would like to do this with a few clicks (define left/right edge or something similar)
thanks for any suggestions

You can do it using faces. Select a face then Right Click > Align View.

Thanks, that helps in some way, although I'm not sure I understand completely.
Align View aligns with the normal vector of the face, ie I could get the viewing direction after ensuring the lines are of equal length, but I still would need a tool or a way to set the FOV itself (i don't want to guess it using the zoom tool).
EDIT: ok, it kinda works, I think I'm fine with guessing the FOV for now. The way used this was that I created a face perpendicular to the viewing direction, set the camera with Align View, position the camera and then eyeball the field of view so that the face's edges are aligned with my screen.

The problem is that there is no correct FOV. Adjusting the FOV is essentially the same as picking a camera lens size - it's up to your own judgment as to what looks best.

in this case, there IS a correct FOV to be had, and it's the angle between the two lines defined in the brief. I was looking for a way to get it correctly from the geometry, not having to measure and type in the angle.

That isn't the FOV (not how it works when setting FOV in Sketchup anyway). You are describing a viewing position dictated by the middle distance between two points.
You could temporarily draw a plane between the two lines and then use that with Align View.
