This page contains EDMInterface API sample code to show how to exploit the powerful features of EDMqueryMethods. To run these samples, you need to create an EDMdatabase and compile the following schemas.

The Industry Foundation Classes (IFC) data model to describe building and construction industry data

Defines the EDMqueryMethods CheckModelCapacityUsed(), CheckEDMserverVersion() and GetMaxModelInstances(). Extends the IFC2x3 EXPRESS Schema

Depending on which sample you look at, you may also also need to import the following data sets.

 

Sample population with one instance of IFCWALLSTANDARDCASE, identified by a GUID

 

Sample population with three instances of IFCWALLSTANDARDCASE, with duplicate GUIDs

 

Sample population with one instance of IFCWALLSTANDARDCASE, with simple geometry.

 

Sample population with one instance of IFCWALLSTANDARDCASE, with pSet_WallCommon property set.

EDMqueryMethod with output in QueryResult table

This sample shows how to executes an EDMqueryMethod. In the sample, input arguments to the Query are provided as SELECT type parameters, and the output data is returned as a QueryResult Table allocated in the calling clients heap memory.
