as you know, two-point perspective or vertical tilt shift is a critical feature in arch viz, and is almost always turned on when I export my image.
Another nice feature would be a button that aligned the camera perpendicular (e.g. front/back/left/right) to the view so that the grid like elements in the scene are 'flat' and not skewed.
For example, when I render a scene with a ceiling grid, it is really hard to make sure the camera is perpendicular to the scene, causing the ceiling grid to be ever so slightly skewed to one side of the view.
The only solution right now is to use num pad to align the camera perfectly to front/back/left/right, but again the problem is moving the camera up/down with mouse makes it no longer perfectly perpendicular.
Right now, the num pad align view sets the camera to 'zoom extent' when aligning to front/back/left/right. As you may imagine, this is not particularly useful especially when you have a scene with large context/environment/landscape. It causes the camera to pull back wayyyy outside. It would be nice if the numpad did not zoom or recenter the camera to the middle, but simply snapped the camera to perpendiculars. That way, I find my view I want, then press the numpad to make the camera perfectly perpendicular to the scene.
This solution only works when the building is aligned to the main axis. But it would still be a nice feature to the workflow.
