You cannot delete Object Types or Association Types, if instances exist in the repository. You can however get round this by using the Design Synchronizer. This "unofficial" utility aligns one model with another. If the source model does not include Object Type X, then Object Type X and all its instances - even if they are on a diagram - will be deleted in the target model.
