ANSI SQL
| A specification describing the official features of the SQL database language. Every variant of SQL relational databases implements a subset of ANSI SQL.
|
| ProductURL | A named aggregation of BIM objects that form another object or functional unit
|
Associative Dimensioning
| A function of a BIM authoring system that automatically updates the value of a dimension when changes occur to the geometry of the object.
|
| BIM Authoring System | An application used for generating data for multiple uses that includes 3D geometric information. EXAMPLES: Autodesk® Revit®, Bentley® AECOsim®, Graphisoft® ArchiCAD®, Nemetschek® Vectorworks® and Tekla® Structures.
|
COBie
| Construction Operation Buildings information exchange. A representation of a handover view of the IFC schema, typically seen as a spreadsheet (ISO 15686-4).
|
| Field | A data field is a place where data is stored. Commonly used to refer to a column in a database or a field in a data entry form or web form. It is generally the smallest component under which data is captured. This standard applies the concept of fields to the components of a name (property/file/view) which stores a specific piece of information.
|
Generic Object
| A generic representation of the common features and properties of a physical element, intended for use in the early stages of design or when the object is not resolved into a product.
|
| Hard-coded | A field that is coded into a software user interface where the user has no ability to change the field name.
|
IFC
| Industrial Foundation Classes (ISO 16739). An open file format developed and maintained by buildingSMART for the exchange of information enhanced models.
|
| Insertion Point | The point on an object used to place it into a model.
|
Layered Objects
| An object typically constructed from one or more layers of materials to form a building system. Typically these are “system” objects, provided by the BIM Authoring System without fixed geometry, where the user can modify the layers and thickness but the geometry is created on placement in the model.
|
| Library | A collection of reusable BIM objects stored as separate files that are used to facilitate the use of standardised designed or manufactured elements and objects over a project or series of projects.
|
Metadata
| The term for the collection of properties, names, or data associated with an object, element or file. (Can also be known as Attributes, Parameters and Properties).
|
| Origin Point | A fixed point of reference for the geometry of the surrounding space defined as X, Y, and Z. Objects have an origin point that all other points in the object reference. A model has an origin point and objects placed in the model reference this.
|
Parametric
| The use of pre-programmed rules or algorithms to provide the user with the ability to change or configure objects during modelling.
|
| Property | A characteristic, feature or measurable factor associated with an object that can help define the object (or system). (Can also be known as Attribute, Parameter or Metadata).
|
Property Set
| A grouping of properties that belong together based on some principle, e.g. viewpoint, lifecycle stage. (ISO 15686-4).
|
Proprietary Object
| A representation of the common features and properties of an obtainable product.
|
| View Control | A function within the BIM Authoring System that controls which objects, or parts of objects, are visible at any time in a model BIM Authoring Systems control object viewing in different ways, such as layers or subcategories.
