(3) Horizontal line
(a) When the immediately preceding block is pending, and contact
point determination is not specified
i) When the X coordinate of a horizontal line is entered
The intersection with the immediately preceding figure
block is calculated. However, this figure is pending.
Intersection
X
When the immediately preceding block specifies an arc,
the intersection selection request screen appears. Press
[CROSS 1] or [CROSS 2], then press [INSERT] (or
[ALTER] or [ALTER FIGURE] to change the figure).
ii) When the X coordinate (X) of a horizontal line is entered,
together with the Z coordinate (Z) of an end point, or a line
length (W)
The intersection with the immediately preceding figure
block is calculated, and the end point is determined.

(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 horizontal line
specified at figure selection)
Usually, a contact point is automatically calculated from
the rotation direction of the arc and the direction of the
horizontal line. The horizontal 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 Z coordinate (Z) of an end point, or a line length (W)
is entered
In the same way as in i) above, a contact point is
automatically calculated, and the end point of the
horizontal line is determined.
