Benefit of Two-Point Perspective mode?
-
Any practical purposes?
-
It allows you to make 2D Perspective views. Vertical lines in the model will be shown as vertical while horizontal lines will recede toward vanishing points.

So it's more for making printouts/presentations than for modeling?
-
Yes. If you orbit around the model after setting the Camera to 2-Point, it will revert back to Perspective.
2-point allows you to make views similar to those made with a Shift lens or a view camera. For tall things it keeps them from looking like they are leaning backward. Parallel Projection makes the vertical lines vertical, too. the horizontal lines are parallel to each other so things that are farther away from the camera are not displayed as smaller as they would be in perspective views (2 or 3-point).

Hi, I need this plugin. Where to find it?

If I am not wrong, it's native Sketchup Menu / Camera / Perspective 2 Points

What plugin? Two-point perspective is in the Camera menu as Pilou guessed.

Hi
also I use SU´s 2-point perspective almost for each project. and yes, the main reason is to get illustrations for print for example. Vertical edges or lines, which are parallel to the picture frame, are preferred for print mostly - at least in my working conditions.I would like to point to a certain point. I think most render tools can handle SU's 2-point perspective. But there are render tools, which can´t understand this kind of views, such as Render[IN] for example. So it is worth to check out whether the SU views function in the selected renderer before rendering.
Render[IN] or ArtLantis for example offer an own tool for tranfering a perspective into a 2-point perspective. Or there are some external tool like "ShiftN", Pilou posted the link to this great tool somewhere here in the forum a few weeks ago ...

Two-point perspective is just a special case of three-point perspective in which the camera is oriented parallel to the horizontal plane. SketchUp's two-point perspective mode is a fast and exact way to point the camera that way (you could do it manually if your orbit skills are good enough). That's why you lose the mode when you orbit any direction except perfectly horizontally. As noted, all this orientation does is to cause vertical (parallel to blue axis) lines not to converge in the view. Parallel to any other plane will cause the same effect for lines perpendicular to that plane.
When viewing real 3D objects, our two-eyed visual system blends depth and direction of view with perspective and we interpret converging edges as really being parallel. Tricking that system is the basis of many optical illusions.
But on a 2D image or computer screen there is no binocular depth available and view direction is toward the screen no matter what the model orientation in the view, so our visual system can't do the interpretation correctly. As a result, three-point perspective can look exaggerated and unrealistic, especially when viewing an object from up close or with a wide angle camera. Two-point perspective tends to give the visual system an easier task to interpret the underlying 3D.

I like the explanations everyone has give here. I have never used 2-point perspective so thought this was very informative.
Maybe a little off topic but I like to use the parallel view when aligning things (at least for the type of models I do) but then I switch to perspective mode when doing everything else. I just find it a little easier (for me) to do the alignments in parallel especially when I have components with subcomponents.
