Merging models

[Harvey Stockwell]

Hello
I have a question regarding IModel_DG. I need to add object from an .mdg file to the scene in my application.

I do loading like:

Code: Select all

	IDIObjGenerator iGener = _iModel as IDIObjGenerator;
	IModel iModelAnother = (IModel)iGener->Create(EObjectType.eObjTypeModelGenerator);
	IModelEx iModelEx = iModelAnother as IModelEx;
	iModelEx.Load( modelPath);

_iModel here is the main model of the application

A neat way would be to use

Code: Select all

	IEntityArray_DG entities = iModelAnother.GetEntityArray(includeDescendents);
	_iModel.Add(entities, -1);

So my question is what should I put for includeDescendents here? What is the meaning of the parameter?

Thank you

Hello Harvey
includeDescendents must be false in the case.

When it is true the returned array is a flattened list, where all entitles in the tree is listed in one array. Adding it to a model would cause an exception, I think, when there are children, as they would be added twice
