Thank you... I am always happy when someone likes it.

If you want ungroup the models, there is a simple solution. Open the model in MED, delete everything except the model you want to interact with. Then save this model under a different name. Next, open the grouped model again, delete the part you just saved under a different name and seve the grouped model. IN your level combine the two models you just created and there you go.

Hope this helped a little.
