Hello, my structure is similar to the one of the digital wristwatch example. I have a Family Metamodel Graph Type and an Application Graph Type. I started to build the Generator for my FamilyGraph, which has an Application Graph as a Subgraph. I need to integrate information from there, how can I do that?  Thanks, Dagijoana |

Hello Dagijoana!
You can use the http://www.metacase.com/support/45/manuals/mwb/Mw-5_3_4.html#_Ref190593893 - - do decompositions commands, depending on which type of subgraph link you want to follow. Inside the do loop you'll be in the subgraph, and can use a foreach loop to iterate over the objects etc.
It's normally a good idea to run a subreport for the things you want to do in the subgraph. The top level generator will be in your FamilyGraph graph type, and the subgenerator will be in your ApplicationGraph graph type. E.g. in FamilyGraph you might have:
foreach .ApplicationObject
{ do decompositions
{ subreport 'AppCode' run
}
}
To create the AppCode subreport in ApplicationGraph rather than FamilyGraph, open a new Generator Editor for ApplicationGraph (or use Generator | Change Graph Type... in an open Generator Editor).
