Consider the rules governing steel fabrication elements in a worksharing environment.
Reload Latest: If you use the Undo command on Reload Latest, bringing back changes applied to steel fabrication elements into the user model, the Undo command will no longer be available for actions completed prior to the Reload Latest operation.
Synchronize with Central: In a user model, the Undo command is not available for actions involving fabrication steel elements after using the Synchronize with Central command, even if you use the option to relinquish borrowed elements. However, you can use Undo to reverse operations that do not affect steel fabrication elements.
Beam or Plate: When you create structural steel beams or plates, no other elements are checked-out.
Connections, Welds, Bolts, or Anchors
Shear Studs: When you create shear studs, a weld is also created. Therefore, you also check-out the elements connected by the respective weld.
Shorten Cuts, Copes, Cuts, and Parametric Cuts
Beam or Plate: When you make geometry changes to structural steel beams or plates, besides the actual elements, you also check-out all bolts, anchors and connections created on the modified beams or plates. Shear studs will not be checked-out in this case, as they do not have a direct relation to the structural steel elements or plates.
Connection
Shear Studs: When you make changes to shear studs, no other elements are checked-out along with them.
Welds: When you make changes to welds, no other elements are checked-out along with them.
Bolts or Anchors
Shorten Cuts, Copes, Cuts, and Parametric Cuts
Beam or Plate : When you delete structural steel beams or plates, besides the actual elements, you also check-out all bolts, anchors, welds and connections created on the deleted beams or plates. Shear studs will not be checked-out in this case, as they do not have a direct relation to the structural steel beams or plates.
Connection
Shear Studs: When you delete shear studs, you also check-out the weld that connects the shear studs to the beam or plate.
Welds: When you delete a weld, you also check-out the elements connected by the weld.
