Parent page: Schematic Query Functions - Membership Checks


For numeric properties of objects (e.g. length, width, radius, etc), this keyword is used to convert the current value - measured in the default workspace units - into imperial units - mil - where 1mil = 0.001inch, which is then tested against the value entered in the expression.

You will need to target a specific object first, within the same Query expression, before using this keyword to effectively convert the specified property's value to mils.


AsMils(Keyword : Number) : Number

Example Usage

IsArc And (AsMils(Radius) = 250)
Returns all arc objects that have a Radius property which is 250mil.

IsPort And (AsMils(Height) Between 100 And 120)
Returns all port objects that have a Height property which is greater than, or equal to, 100mil, and less than, or equal to, 120mil.
