We have recently upgraded from SW 2011 to 2012 and I have tried for the first time to use my forming tools. All of my forming tools now error after inserting them.

The error I get is 'This feature will create disjoint bodies. Multiple sheet metal bodies are not supported'

I am using a vent and rib tool.

This error is occuring when inserting my tried and tested tools from 2011 into the same parts that have the original features created from these tools.

Anyone know a solution?

Thanks
