Argument |
Contents |
|
a_unit |
The first measurement unit |
|
b_unit |
The second measurement unit |
A real number that is equal to the number of b_units in an a_unit.
GetUnitSize() works with both map and paper units, in any combination.
Both a_unit and b_unit must use the plural form (e.g., Miles, Inches, etc.).
inches_in_a_mile = GetUnitSize("Miles", "Inches")
|
curr_units = GetMapUnits("Plural") |
// What units are in use? |
|
Five_miles = 5.0 * GetUnitSize("Miles", curr_units) |
// convert miles to current units |
|
n = SelectByCircle(, "Several", Circle(ctr, Five_miles)) |
// select features within 5 miles |
