MDB improvements - Additional indicators

[gilsdorf_e]

I'm just digging deeper into §D model based definition. For some cases I can find no good visualization option.

For example ISO 1011 includes further indicators (CZ = Common Zone, etc.).

If I add an MDB to multiple faces, Inventor seems to notice that internally. The type is displayed for example as

"coplanar group". 

If these faces are not independent but have a common tolerance, this should be indicated by 'CZ'. Still I find no way to do this, also you cannot add additional leaders.
