Example (based on pure API calls)

Here you can find code snippets that show how the API call engiGetAttrNameByIndex can be used.

using RDF;      //  include at least engine.cs within your solution

Int64 WriteEntityStructure(Int64 ifcEntity)
{
    if (ifcEntity != 0)
    {
        //
        //  Iterate over the parents
        //
        Int64 attributeCnt = WriteEntityStructure(ifcengine.engiGetEntityParent(ifcEntity));

        //
        //  Print Entity name
        //
        IntPtr entityName = ifcengine.engiGetEntityName(ifcEntity);
        Console.WriteLine("Entity  " + entityName);

        //

        while  (attributeCnt < ifcengine.engiGetEntityNoArguments(ifcEntity)) {
            string attributeName = ifcengine.engiGetEntityArgumentName(ifcEntity, attributeCnt);
            Int64 attributeType = 0;
