Drag the compass and place it with the Z axis
pointing in the direction with which you want to make the segment parallel.
Bring up the Definition
dialog box for the run.
Bring up the Definition dialog box
again, this time for the segment half you are interested in. See note
Each segment is divided into two
halves, which become visible when you bring up the Definition dialog box
for the run. It is important to select the correct half, because the
segment will pivot at the node closest to the segment half you select.
Click on the Compass Z Direction
segment will pivot - at the node closest to the segment half you selected -
to become parallel with the Z axis of the compass.
NOTE: Place the compass carefully because segments also have a
directional relationship to the compass. The node that pivots will parallel
the base of the compass. The node at the other end will parallel
the Z vector.
