Formulas for counting lines by attributes

The formulas that follow count how many lines there are according to:

• The angle at which the lines are positioned in the design.
• The style applied to them.

The formula is handy when inliner production is used and you need precise data about the positioning of creases.

Formula patterns

TO print	Use
Number of lines (1up)	$OneUpN.ToolPosCount(StyleName; ToolDirection; Tolerance)$
Number of lines (layout)	$LayoutN.ToolPosCount(StyleName; ToolDirection; Tolerance)$

NOTES:

• STYLENAME. The name of the style applied to the objects that are to be counted.
• TOOLDIRECTION. The value of the angle that determines the object's direction relative to the x-axis — for example, 0, 45, 90.
• TOLERANCE. The variation from the angle value set in ToolDirection in which the object will still be counted.

USAGE NOTE: In the formula, type a value for the tolerance — for example, 1, 2, 0.5, 0.25 (see examples below). If you do not want to use a tolerance variation, type zero (0).

DEFAULT TOLERANCE NOTE: The EngView applies a standard, system-set tolerance — $epsa()$ (for angles, 0.001 degrees) and $epsd()$ (for distances, 0.0002 in the selected metrics).

NOTE ON ROTATED DESIGNS: If the design is rotated, the formulas require that the angle of rotation is entered — see the parameter ToolDirection in the formulas' syntaxes. In this case, the measurements are again made relative to the leftmost edge of the bounding rectangle, which, too, is rotated at the same angle as the design.

Applying the formula

Examine the following 1up drawing and then the example to learn how to apply the formula.

TO print	USE	Example
How many creasing lines there are in a design in the position determined by the angle.	$OneUp1.ToolPosCount(Creasing; 90; epsa())$	4
