#### 8.8.3.8 IfcMaterialProfile

| Matériau de profil
| Profil mit Material

IfcMaterialProfile is a single and identifiable cross section of an element which is constructed of a number of profiles (one or more).

> NOTE In case of multiple MaterialProfiles, the relative positioning of individual profiles in IfcMaterialProfileSet are defined using the concept of IfcCompositeProfileDef in IfcProfileResource schema; otherwise, only one MaterialProfile is given and defined by an individual IfcProfileDef (subtype).

Attribute Definitions:

Name | : | The name by which the material profile is known.
Description | : | Definition of the material profile in descriptive terms.
Material | : | Optional reference to the material from which the profile is constructed.
Profile | : | Identification of the profile for which this material profile is associating material.
Priority | : | The relative priority of the profile, expressed as ratio measure, normalised to 0..1. Controls how profiles intersect in connections and corners of building elements: A profile from one element protrudes into (i.e. displaces) a profile from another element in a joint of these elements if the former element's profile has higher priority than the latter. The priority value for a material profile in an element has to be set and maintained by software applications in relation to the material profiles in connected elements.
Category | : | Category of the material profile, e.g. the role it has in the profile set it belongs to.
ToMaterialProfileSet | : | Material profile set in which this material profile is included.
