The family tables in Content Center are not able to use in all features in Inventor. Especially for tubes we face the problem that those tables must be duplicated to use it on the first side in Frame Generator and on the other side in Tubes&Pipes.

In general the problem is on changes it must be reworked always twice and so the mistake potential is higher.
May you can find a way, that some tables can be used in more features.
Thank you, BR Erhard
