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 inches, 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 inches.


AsInches(Keyword : Number) : Number

Example Usage

IsArc And (AsInches(Radius) = 0.219)

IsPort And (AsInches(Height) Between 0.254 And 0.294)
Returns all port objects that have a Height property which is greater than, or equal to, 0.254in, and less than, or equal to, 0.294in.
