BOC mark position
An expression to convert the BOS mark position data into the standard coordinate system is
defined.

7.3.3 Custom transformation settings (placement) screen
In coordinate transformation of the "Global Setup" screen, specify "Custom transformation" and
click the button. Then, the "Custom transformation settings (placement)"screen is displayed.

An expression to convert the placement data into the standard coordinate system is defined.
Figure 7.3.3-2 Placement Coordinates
As one method of specifying the placement angle, a conditional expression can be set.
Check off "Use conditional expression to specify placement angle" to display the input screen
using the conditional expression.

<Exercise 1>
* Try to make a calculation on the supposition of X coordinate = 50, Y coordinate = 35, PWB
dimension X = 300, and PWB dimension Y = 200.
In the case of X = [X] + [0] + [0]X - Board + [0], the X value after transformation is 50.
In the case of X = [X] + [0] + [1]X - Board + [0], the X value after transformation is 350.
In the case of X = [0] + [Y] + [0]X - Board + [0], the X value after transformation is 35.
In the case of X = [X] + [0] + [-1]X - Board + [0], the X value after transformation is -250.
In the case of X = [X] + [0] + [0]X - Board + [10], the X value after transformation is 60.
In the case of Y = [0] + [Y] + [0]Y - Board + [0], the Y value after transformation is 35.
In the case of Y = [0] + [Y] + [1]Y - Board + [0], the Y value after transformation is 235.
<Exercise 2>
* The bottom-side placement coordinates are defined in the coordinate system viewed from
the top side as shown in the following figure, transformation is required.

This point becomes an origin as
viewed from the bottom side.
Consequently, it becomes as shown below.
At this time, the expression is as follows:.
X = [-X] + [0] + [1]X-Board + [-10] = -95+0+150-10 = 45
When converting the placement data, it is defined that numeric data should be converted by
user-defined wizard but no data exists in the file to be actually converted. In this case, 0 is set
as the default value in the field of the output file.
