When you go into in-place editing mode, ADT creates in-place edit profiles
for each component which represents the endcap geometry. If you select wall,
ADT will automatically select the first in-place edit profile in the list.
To select a particular component endcap geometry you have to select the
corresponding wall component in-place edit profile by selecting the hatch.
If the polyline for a wall component endcap has more than one segment (edge)
only then you will see the grips.
Hope this helps,
