Point 1 determines the placement of the dimension line.
Pre-select control points to be dimensioned
Adds a single, parallel dimensioning component to the current group.
line goes through the point P. The difference to
dimensioning at an angle is that exactly
two pre-selected points, P1 and
are used to create the parallel dimensioning component.
Instead of requesting the angle of the dimension line
from the user it is calculated from the two dimensioned points so that the
dimension line is always parallel.
