Hi all,

Here's my experience with IMgaFilter: 

Do look at the following code for a better understanding. You can cut&paste this code directly in your raw com interpreter and it should work. Assumptions : 'project' is a (IMgaProject) pointer to the current project. 
The way that works for me is to search for stuff with kind name. set bstrKind to the kind of the required FCO. 

Hope this helps!

Cheers,
Kumar

Can anyone explain to me how IMgaFilter works? I haven't been very successful trying to get it to work on my own. 

I want to be able to get all atoms or models from a project. Or, get all of a certain kind from the meta from a project using IMgaProject->AllFCOs, but I have been having trouble setting the properties of the IMgaFilter.
