which is fastest way to rotate view aligned with element plane but keeping view Z rotation up?
The attached file is simplified workflow when dealing with reality models. The issue is that if reality mesh model of a building is not aligned with drawing axis then it is not easy to rotate view which is aligned with facades. As it is not parametric model there are no straight lines to snap to.
Create 4 saved views(or ACS) so each view is aligned with each of mesh faces(red) but keeping Z axis vertical so the black outline is orthogonal. Outline is not snappable and is only a reference it is allowed to snap to red mesh only.
This method seems pretty simple:
Here's a short video to illustrate the method:
This may work I have to check if this same approach could work with reality meshes. If trim will not work then I could project line on mesh and try to use that.. Only issue that for some reason it doesn't perfectly align with the outline.

Its a classic example of how you can solve a problem in MicroStation in many different ways, each one formulated by different people with a different mindset on how to approach the challenge.
While I find the ACSes knowledge important I think in a Reality Capture scenario (with more buildings) it may not be what you want. Serveral ACSes for several buildings?
@Oto: What line of work are your trainees and what are they trying to achieve after this rotation step?

If the situation demands it, then absolutely yes. If you have a building/object where the sides are orthogonal to each other but not to the world, then a single ACS will suffice however, the provided mesh doesn't have orthogonal sides (on the base edges), so Oto's condition set out in the opening post :
Oto said:Create 4 saved views(or ACS) so each view is aligned with each of mesh faces(red)
correctly requires 4No. different ACS. When I create 3D models, I always aim to keep orthogonal sides/elevations parallel to the XY axis of the world coordinate system yet there may be elevations which are angular so for these I would always use at least 1 custom ACS.

Trainees would like to utilize Reality Models and/or Point Clouds. Problem is that existing workfows are not suitable for utilizing such data and also most examples in tutorials are too simplified. As reality models can't be exported to BIM formats then trainees would like to digitize them as CAD models before using in BIM. Without correctly aligning the models they can get wrong measurements and if wall of building is not straight or angle between walls is not 90 degrees as expected they could model them incorrectly. When reality strikes BIM then it becomes complicated.
Right, the expectation is that floors in buildings are level/not dipping. The terrain though is often slanted.
In a laserscanning SW I have seen a measurement function that always offers the measurement results as horizontal/vertical value.(horizontal distance and hight) Would be nice to have that in microStation.
