    on the object Rename may be used to change the name of an object for objects requiring unique names property sets concept templates schema definitions etc Move Up Down is available for re ordering items defined in a particular order such as properties Move In Out is available for promoting or demoting items in hierarchies such as concept templates and examples Model View Definition becomes available when selecting a Model View Configure Schema reads an EXPRESS file exp and includes any definitions within the model view Build Concepts generates Concept rules from property sets View The View menu allows switching among three different view modes within the right pane Web View Text View and Diagram View Web View displays documentation for the selected item as it will appear in a web browser Text View allows editing of documentation in HTML format Diagram View displays a diagram of the current object where applicable for schema definitions it displays EXPRESS G diagrams for model view concept templates it displays instance diagrams for model view concepts and exchanges it displays requirement tables Insert The Insert menu allows new content to be created typically relative to the selected item in the tree It is divided into four submenus as follows Documentation Content only affecting documentation output such as terms references and examples Schema Content describing underlying data structures such as entities enumerations selects and defined types added within a schema sections 5 8 User Data Content describing dynamic data structures such as property sets and quantity sets added within a Schema underneath sections 5 8 Model Views Content describing model view definitions such as templates section 4 model views and exchanges section 1 and concepts underneath entities within sections 5 8 Diagram The Diagram menu provides functions for editing diagrams while in Diagram View Several tool modes are available that impact mouse operations within the diagram Select allows objects to be selected within the diagram Place allows objects to be placed moved and resized by clicking and dragging Link allows objects to be connected such as entities to attributes by clicking from a source object and dragging to a target object In addition to tool modes several formatting features are available in the Diagram menu Use Tree organizes or removes if unchecked lines originating from the selected object subtypes of an entity subtypes of an entity reference or select items into a tree hierarchy to achieve a structured layout The tree may be moved by clicking and dragging the point at the root of the tree Use Page Reference generates or removes if unchecked a page reference label for the selected object and converts all references to the selected object into page references Align positions the selected objects 2 or more such that the left right top or bottom edge is aligned at the same position as the last selected object Make Same Size resizes the selected objects 2 or more such that the width height or both are the same size as the last selected object Space Horizontally moves the selected objects 3 or more such that the horizontal spacing between them is made equal incremented decremented or removed Space Vertically moves the selected objects 3 or more such that the vertical spacing between them is made equal incremented decremented or removed Tools The Tools menu allows content to be generated of various forms Validate File loads an IFC file checks it against a specified model view and generates a report in HTML indicating status of passing or failing Generate Documentation produces documentation in the form of HTML pages conforming to ISO HTML format Generate Report produces documentation within a single HTML file conforming to the U S National BIM Standard V3 Generate Source Code produces boilerplate software code for C or Java languages Generate Module creates a NET assembly as a dll file that includes all data definitions within the schema or filtered and annotated with rules according to a model view Authoring Property Sets and Quantity Sets Property sets refer to extensible data definitions in the IFC specification where custom setting may be defined on particular objects To make use of properties some familiarity with the IFC specification is necessary for example properties attached to a wall are defined for IfcWall within the IfcSharedBldgElements schema in Section 6 Users of application software must also have understanding of how their software maps vendor specific definitions into IFC Various IFC compatible software applications may allow use of custom property sets defined in IFC files Custom property sets may be defined by selecting a Schema and clicking Insert User Data Property Set and then selecting the Property Set and clicking Insert User Data Property for each property to be defined Properties may be edited via clicking Edit Properties To use resulting property sets in supporting applications use File Export and select ifc as the format to generate an IFC file containing templates for properties This file may then be loaded into software applications supporting custom IFC properties As defined in the IFC specification there are seven basic types of properties Single Value a value of a particular data type with optional unit this is the most commonly used and most widely supported type of property Bounded Value similar to Single Value but also including a Minimum and Maximum range which may be useful for defining ranged values such as operating electrical current Enumerated Value a value which must be set to one of several predefined names List Value a list of values of a particular data type Table Value a table of values where each column defines a particular data type This may be used to define available product configurations or graphs of engineering data e g efficiency curves for air conditioning at various temperature differentials etc Reference Value a predefined data structure such as a Time Series which may be used for capturing real time or historical data such as energy usage Complex Value a combination of any of the above properties into

  • certification 2.0 summary — Welcome to buildingSMART-Tech.org
    awards expected Autumn 2013 Details of the IFC Certification 2 0 procedure The IFC Certification 2 0 is an improved implementation of the former IFC2x Certification procedure The most important achievement of the IFC Certification 2 0 procedure is a detailed quality control approach for the IFC interfaces on top of the self check performed by the software developer NOTE The terms 2 0 and IFC2x in conjunction with the term Certification do not determine the applicability of an IFC Release to a Certification Process The IFC2x Certification procedure has been the first official certification specification established in 2002 that is now superseded by the IFC Certification 2 0 procedure in 2010 Principles of the IFC Certification 2 0 procedure The new IFC Certification 2 0 procedure based on the following principles the software certification is bound to a particular IFC Model View Definition supporting one or several Exchange Requirements occurring in the construction and facility management industries the software certification is provided with a conformance test suite containing model creation guideline sets to create comparable export test files with test instructions for export checking automated export file testing based on validation rules that formalize the constraints imposed by the model view definition calibration test files for import checking based on test instructions i e check lists and templates with testing criteria the software certification is managed by a web based database providing the certification center offering central storage and distribution of test guidelines files and instructions central capturing and reporting of test results at different levels of granularity and access rights running the automatic export testing and providing workflow support for manual evaluation processes The workflow of the IFC certification 2 0 procedure is supported by an online database and test center GTDS General Testing and Documentation Server For
