-
Ctrl-drag will translate it linearly along the axis,
without re-aligning the axis.
-
Scaling Points: Drag the cubes at the end of the axis to
scale selected PEPs about the center of the jack. Shift-drag
constrains the scale to a single plane.
-
Rotating Points: Drag the rotate knobs to rotate the
selected PEPs about the center of the jack.
-
Drag for uniform scaling.
-
Shift-drag for free rotation about center

Snapping the PEP Jack: If the Snap Target is enabled, then
the PEP translation will snap to the target. For details, see Aligning Points, Edges, and
Polygons.
