I need an isometric, trimetric, or dimetric section view of an assembly in a drawing similar to images below.

It has to be oriented vertically with a 150 degree cut instead of a 90 degree cut.  I have tried making an isometric section view from a half section view but that has limitations and only seems to work on a 90 degree cut.

I need to exclude some components from being cut like below right.  I realize I could fake it by creating an assembly cut excluding some components then hatching manually in the drawing view but that is... well... faking it and cumbersome.

Any ideas would be appreciated.
