Units and Numeric Values in Scripts

Numeric values which are associated with unit markings follow these rules:

VectorScript will scan for all legal predefined unit marks when parsing numeric values. If illegal characters are found after numeric values, a VectorScript warning will be generated.

VectorScript will not scan for user-defined unit marks.

Numeric values in VectorScript which are bound to a unit marking will be sized to be accurate to their unit mark within the current units setting of the active document. For example:

 

Rect(a,a,a + 1'2",a + 1'2");

will always draw a rectangle that is 14” on a side independent of the units setting, and

 

Rect(a,a,a + 14cm,a + 14cm);

will always draw a rectangle which is 14 centimeters on a side, independent of the document unit setting.

Numeric values which are not bound to a unit marking will be sized to the current units setting of the document. For example:

 

Rect(a,a,a + 14,a + 14);

will draw a rectangle 14 document units on a side. If the current units setting is Feet, the rectangle will be 14 feet on a side; if the units setting is millimeters, the rectangle drawn will be 14 mm on a side.

Numeric constants are bound to any specified unit mark. For example:

 

CONST

kX = 5.5cm;

will be bound to and retain its centimeter unit marking.
