Autodesk Robot Structural Analysis

[#1]

I am using rigid links on a structure to simulate lifting lugs on the perimeter of the structure.  When creating the rigid link there is an option to specify "Blocked Directions" there are checkboxes for UX, UY, UZ, RX, RY and RZ. Would somebody be able to explain to me what RSA means by these "Blocked Directions"?

Also, Which node do you select as the Master/ Slave when creating these rigid links? And is there a way to delete a rigid link if you no longer wish to use it?

Thank you,

Jared
