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 metric units - cm - where 1cm = 0.01meter, 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 cm.


AsCM(Keyword : Number) : Number

Example Usage

IsArc And (AsCM(Radius) = 0.56)
Returns all arc objects that have a Radius property which is 0.56cm.

IsPort And (AsCM(Width) Between 1.27 And 2.79)
Returns all port objects that have a Width property which is greater than, or equal to, 1.27cm, and less than, or equal to, 2.79cm.
