• Insert a Find Mark command for the
mark you created in the previous
procedure. Be sure to enter the Mark
No.
• Insert a Step & Repeat X command and
specify the parameters for this example:
- The values for XOFFSET and
YOFFSET represent the length and
orientation (horizontal or vertical) of
the line.
- The value for COLUMNS (X) sets how
many times you want the camera to
view the line and make adjustments.
- For ROW, enter 1.
- For LABEL, enter 1.
NOTE: The XOffset value multiplied
by the number of Columns cannot be
greater than the total length of the line.
Because there is only one row, the
S.Path / N. Path parameter does not
have an effect.
