Property model

Size: 32 bit / 4 byte (value)
The handle to the model. The model handle is static during its existance. Several models can be opened simultaniously within one session. Different models are always independent, threads are allowed to be running on different models simultaniously.

Property entity

Size: 32 bit / 4 byte (value)

Example (based on pure API calls)

Here you can find code snippits that show how the API call sdaiGetEntityExtent can be used.

C++ 32 bit
C++ 64 bit
C# 32 bit
C# 64 bit
#include    "./include/ifcengine.h"
int_t   localGetEntityExtentBN(int_t model, char * entityName)
{
    //
    //  This function is an alternative to the API call sdaiGetEntityExtentBN()
    //  based on sdaiGetEntityExtent().
    //
    //  Use of sdaiGetEntityExtent() can lead to performance improvement compared to sdaiGetEntityExtentBN().
    //
    int_t   entity = sdaiGetEntity(model, entityName);

    return  sdaiGetEntityExtent(model, entity);
