R
Arc for which the X coordinate (I) and Z coordinate (K) of its
center have been entered (A start point is determined. This arc
is pending.)
Slanted line (pending)
Data other than direction data cannot be entered.
Arc for which its radius (R), and the X coordinate (I) and Z
coordinate (K) of its center have been entered
The end points of figures and are determined, and the
arc of is pending. Four slanted lines form tangents to the
two arcs as shown above. Depending on the directions of
rotation of the two arcs, the slanted line that makes a smooth
connection to the arcs is automatically selected.
