(b) When the immediately preceding figure block specifies a pending
arc, and contact point determination is specified
i) When no data is entered (with the direction of a vertical line
specified at figure selection)
Usually, a contact point is automatically calculated from
the rotation direction of the arc and the direction of the
vertical line. The vertical line is pending.
If any of the specified directions is invalid, however, a warning
message is displayed to indicate that invalid data has been entered.
ii) When the X coordinate (X) of an end point, or a line length
(W) is entered.

2 When an angle of 90° or greater is entered, a warning
message is displayed to indicate that invalid data has been
entered.
(a) When the immediately preceding figure block is not pending
i) When a line length (Q) and angle (J) are entered, or
ii) When a line length (Q), and the X component (I) and the Z
component (K) of an angle are entered
The end point of a slanted line is determined.

iii) When an angle (J), and the X coordinate (X) or Z coordinate
(Z) of an end point are entered, or
iv) When the X component (I) and Z component (K) of an angle,
and the X coordinate (X) or Z coordinate (Z) of an end point
are entered
The end point of a slanted line is determined
