Have you tried to select components from the content centre when setting up a bolted connection, but the fasteners you require don’t appear in the list? This is due to the bolt and nut thread classes not being the same.
This can be changed in the content centre editor by locating the family member in the content centre. Right click on the member, select ‘Copy To’ and select the custom content centre library (the library will need to be created in order to be able to have write access).
You will now be able to edit the family member in the custom library by right clicking and selecting ‘Family Table’.
You can then edit the family table and change the thread class columns in both the bolt and nut family tables to match and you will then be able to select the required content centre member when selecting from the ‘Bolted Connection Component Generator’ dialogue box.
