How to clean orphan associations?

In the process of creating a complex domain model I ended up in having a lot of orphan associations (i.e., associations that are not visible in any of the diagram but still exist in model) that are generating a lot of trash code. It is quit difficult to analyse many hundreds of relations from class specification to see whether it is required or not. Is there any way to get a list of such associations or even delete them all together.

Hi Wsalik,

You can find out the model element which not presented in any diagrams by right click on the project root node in Model Explorer and select Viewless Model Element (see attached pic). And in latest patch release we will also list out the relationships which do not showing in any diagram. Please update the software to latest patch build (20130820br or later). Details about update to latest patch can be found at

Please note that the enhancement on showing viewless relationship is only available to v10.2. Feel free to contact me for any questions.

Best regards,
Rain Wong
