prospect distortion/angle

[poina]

Hi.
I have a problem, I would like to change the perspective in revit to change the distortion, but I can not change the focal angle, because it makes me change only the focal length

I read the discussion, it is only about symmetry of the room, but not of perspective, I would like to correct the focal angle

you can only, by clicking on the edges of the 3d view window, change the size of the crop
that equals the increase of the angle of view, but give focal lengths and aperture aperures as in 3dstudio there is no command

see how to change focal length of an objective (virtual or not) is equivalent to changing itsfield angle ("focus angle" is not a correct definition). are two narrowly related sizes.

I don't understand what you mean when you write that you want to change the distortion. If you refer to optical distortions (cuscinet, barrel etc) then if the program does not provide these options you must apply them after postproduction on the final image with one of the many photo editing programs.
if you refer to the effect of the falling lines this depends only on the inclination between the focal plane and the subject resumed.

it was a reference to the falling lines towards the horizon

if by falling lines you refer to the extensions of vertical lines
these will never go on the horizon line but at a third point
which then would be the true 3d view as it is in reality: with three escape points
on the horizon go to meet the parallel lines to the horizontal plane
in some programs in the perspective item there is option 2 escape points
so in that kind of view the vertical lines do not go to their escape point
but they are always vertical.
for my experience see the accurender program, both as an autocad application and as a revit engine up to the 2008 version
where there was this option
in the image attached, with orbit I placed the camera in three points
top, middle and bottom
depending on your needs you need to place the camera at the appropriate point

I have before you venture into making you should study some photographic technique, at least from the point of view of composition and shooting techniques.
spend a half hour frame, in reality, the same subject with two different focal goals and from different points of view serves more than a thousand experiments with software to make available.
