IFC STRUCTURAL TESTBED TESTBED FOR EXCHANGE OF STRUCTURAL

DESIGN MODELS AMONG DESIGN AND ANALYSIS APPLICATION

MODEL VERSION:

TEKLA STRUCTURES

IFC Certification Proposal Draft 1 Page 2

1 TESTBED DESCRIPTION The structural testbed is based on a modified original design of a stadium, where one section had been cut-out and additional element types had been added. It should represent a fair portion of elements used in structural modeling. The testbed comprises: A common source model to testing the IFC exchange A description of the test model based on the structural modeling elements and attributes used A description of test criteria against which the result is validated A realization of the same test model in (at least) two structural modeling applications A set of IFC export files (from the source applications) with well documented export options A set of success/failure descriptions for external neutral test tools

In IFC syntax checker, In IFC validation tools, In IFC viewer

A matrix of success/failure descriptions for import into other software Matrix based on test criteria and importing software Importing software is either:

Other BIM tools (architectural/ structural modelling software), or Structural analysis software

1.1 Test model description The first test model has been created in TEKLA structures It deals with the main elements: Column Beam Brace Wall Slab

The original test model has been created and exported to IFC using:

2 EXPORT TEST OF THE TEST MODEL The export test contains various test procedures and criteria that should be performed by the applicant before submitting the test case for validation and approval. It includes the following steps: Export the IFC file Verify the IFC file for a correct header Verify the IFC file within a syntax checker Verify the IFC file for basic information, e.g. units, etc. Verify the IFC file within a free viewer

2.1 Verify the correct IFC file header The IFC header has to contain the basic information about the application that created the exchange file. The IFC header can be accessed by opening the IFC file with a simple text editor. Content of the IFC file header Check correct

information ifc_test2.ifc ISO-10303-21; HEADER; FILE_DESCRIPTION(('IFC2X3.exp'),'2;1'); FILE_NAME('C:\\Documents and Settings\\SDoolan\\Desktop\\ifc_test2','2008-03-14T09:06:20',('Steel2 macro version:13.0 Build:276376,10.4.2007'),('Structural Designer'),'EXPRESS Data Manager version:20040806','Tekla Structures 13.0',''); FILE_SCHEMA(('IFC2X3')); ENDSEC;

Export date/time correct Correct IFC Schema

2.2 Verify within a syntax checker Run the generated IFC file against a syntax checker. Make sure that there are no syntax errors against the IFC schema. If you are uncertain if a certain syntax error is produced erroneously, report the error together with the FC export file. Example for a syntax checker is the IfcObjCounter. See http://www.ifcwiki.org/index.php/Free_Software

Name of the IFC syntax checker

Version number, IFC schema version used

Results of the syntax check

IfcObjectCounter V2.9a IFC2x3 No failures


2.3 Verify within a viewer Choose one or several IFC viewers to verify the result. Verify both the geometry of the result, as well as the spatial structure and the attribute content. Examples for a free viewer are the IfcStoreyView, the DDS Viewer or the Ifc Engine Viewer. See http://www.ifcwiki.org/index.php/Free_Software

3 IMPORT TEST OF TEST MODEL IN TARGET APPLICATION The export file should be tested in a target application. An extended validation tool that includes the rules to check the conformance against the selected

IFC view and the agreed implementer agreements for that IFC view. A series of import tests by importing the exported test case into other IFC certified applications (or

applications that participates in the certification process).

3.1 Series of import tests The content of the export file can be tested independently in viewers, the own application and by the validation tool. However in order to make sure, that the exchange with the appropriate target applications actually works, it needs to be checked manually by importing into target applications and by validating the information received by and made available to the target application.

3.1.1 Import into Autocad Architecture

Version number IFC built Remarks

AutoCAD Architecture 2008 B.219.0 IFC2x3 (ifc_test2.ifc) Imports with no error messages; entire model is scaled very large and affects element profile dimensioning (see matrix)

Check performed Checking results Remarks Columns Geometry imports correctly Only properties are length and profile; roll

available but is 120 deg off; Beams Geometry imports correctly Only properties are length and profile; roll

available but is 120 deg off Brace Geometry imports correctly Imports as beam; only properties are

length and profile; roll available but is 120 deg off

Wall Geometry imports correctly Thickness reported in width field; alignment reported in justify field

Slab Geometry imports correctly Only property is thickness; boundary points are editable (see matrix)

3.1.2 Import into Revit


Autodesk Revit Structure 2008.0.0 IFC2x3 (ifc_test2.ifc) Error message on import

Check performed Checking results Remarks Columns Geometry imports correctly No element properties; imports column as

an architectural elements (see matrix) Beams Geometry imports correctly Imports as structural framing; new family

correctly Some walls missing; height, length, thickness and material available for straight walls only

Slab Geometry imports correctly Imported as floor, only thickness available
