We have confirmed a bug with the cut representation of sloped Structural Columns in views set to a Coarse Detail Level. (EDIT: the bug seems tied to the symbolic linework that shows only in Coarse). This issue occurs in Revit 2014 SP1 and in prior versions as well.
The Structural Column family in the following example was set to not show pre-cut in plan views. When the Detail Level of plan views is set to Coarse, the cut representation is inaccurate. In this example, the slanted column (End Point Driven) was modeled in an elevation view from Level 1 to Level 5 and later stretched past these extents. A view associated with Level 1 (Fig. 1 – click to enlarge) was modified to have the same cut plane location and bottom plane as another view associated with Level 4 (Fig. 2 – click to enlarge). We expect the cut representation to be unaffected by the view’s Detail Level, however as you can see the column cut representation is incorrect when this is set to Coarse:
Also slanted columns, stairs and probably other categories, are not respecting the view’s Depth Clipping settings and are shown in full projection below the cut plane. Until this bug is resolved, please use caution and avoid setting your plan views to Coarse Detail Level when locating interior objects and equipment around slanted columns.
