Hello everyone!
Question: In which situations we use 2 Point Perspective. For what kind of works? presentation?
2-Point perspective might typically be used in cases where the extreme height of a model–a tall building, for example-- would result in it appearing to be tipping over backward when viewed from a low angle. It’s similar to using the Shift movement of a classic view camera. It makes vertical lines parallel while allowing horizontal lines to recede toward their vanishing points on the horizon.

I like it for perspective views of smaller buildings as well, since all the vertical lines are, well, vertical and possibilities for jagged edges in the image are fewer. Also feels more “relaxed” in some views.

It’s basically used like a tilt shift lens in photography. It allows you to e.g. look slightly upwards to cover a building from street level, while retaining parallel vertical lines parallel.

To set up a good perspective view for architecture I usually suggest:
- Use Position Camera tool to choose a camera position and a proper eye height, that will allow to evaluate the model scale better;
- Use Zoom tool to set up a natural - human like perspective(~55 degrees);
- Turn on Two Point perspective to straighten the image and compose the shot;.
Using a two point perspective is just a simple tip you will see in most interior and exterior photography books and tutorials, as it helps to make the image more stable. The human eye is also very good at picking up slightly aligned edges, so, as a general rule, I usually suggest either using One or Two Point perspective or tilting the camera up or down at least 15 degrees.

I always think it’s quite subjective and depends on the look and feel that’s trying to be achieved. And example without two point perspective, (from a past life).

Back in hand drafting days, 2 point perspectives were a whole lot easier to construct than 3 point, but now that the computer does all that work, that isn’t a driving factor. It’s just whatever looks right, and it only takes seconds to try it both ways.
