Detailed Description

An IfcConstraint is used to define a constraint or limiting value or boundary condition that can be applied to an object or to the value of a property.

Constraints can be subdivided into user-defined constraints and system-defined constraints. User-defined constraints are applied by a user and are restricted to high-level definitions such as object properties. System-defined constraints can apply to any object attribute, are typically defined by an application to enforce data validation or parametric behavior, and are intended to be enforced by applications but not to be directly editable by an end-user.

Remarks
This definition may not be instantiated.
