Property model

Size: 64 bit / 8 byte (value)

Property entity

Size: 64 bit / 8 byte (value)

Example (based on pure API calls)

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

#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);
