Revit 2019 rotating a view by a small amount makes drawing horizontal and vertical lines drawn without the rotation

[eugeneA979Q]

So, I am working with a point cloud which has more than one building. I aligned one building to be orthogonal. To align another one, I created a level for it, which created a plan view. I then selected the view boundary and use the rotate tool to rotate the view so that a certain building in the point cloud is orthogonal. I used detail lines to do it (one was aligned to a building wall, and the other one was horizontal in the Revit view). I changed the rotation origin, then snapped to the horizontal line, and then to the line, aligned to the building wall. The view rotated. The line, aligned to the wall, became horizontal to the eye (no steps in the line). But when I try to draw a horizontal line, it is not horizontal, but has shifts. Making section lines also positions them on a slight angle, the same angle the view was rotated by. They are drawn vertical or horizontal without the rotation. However, when I create a scope box in the rotated view, the scope box is positioned with the proper rotation, its outline is perfectly orthogonal on the screen. The only way I can actually draw horizontal and vertical lines in this rotated view, is using the initial lines, aligned with the house wall, then use snap overrides and snap new lines to a position, perpendicular to the initial line. When I rotate the view by a larger angle, the problem goes away. The problem occurs only in this instance with a tiny rotation. So, is it a glitch in Revit, or is there something else I am missing here? BTW, the view rotation angle is 0.17 of a degree. I rotated another view by 0.45 degrees, and that one has no issues. Tested it on another computer, the same issue persisted. My first guess is it is a limitation of some sort, and the threshold is somewhere between 0.17 and 0.45 of a degree. Curious if this was fixed in newer releases or with a patch. My version of Revit is 2019.2.3.

Got a word from an experienced Revit user that Revit "doesn't like" anything rotated less than 0.25 degrees from orthogonal. This kind of explains it, I just wish that threshold was smaller. I wonder if newer versions of Revit have improved upon this margin.

You can turn on Work Plane and rotate the plane to align with the angled building (the rotation angle can be smaller than 0.25 degree).  

And if you have multiple buildings, a good practice is create each in its own model and link them using Shared Coordinates.  That way each building is orthogonal locally, yet they are oriented correctly in the master/ site plan.

The experienced user should have let you know all these things.
