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 - mm - where 1mm = 0.001meter, 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 mm.


AsMM(Keyword : Number) : Number

Example Usage

IsArc And (AsMM(Radius) = 6.29)
Returns all arc objects that have a Radius property which is 6.29mm.

IsPort And (AsMM(Height) Between 2.54 And 2.64)
Returns all port objects that have a Height property which is greater than, or equal to, 2.54mm, and less than, or equal to, 2.64mm.
