Chain and Loop Selection 
AutoCAD 2012 includes new Chain or Loop options to simplify the process of selecting a set of 
contiguous edges or curves. 
The new Chain selection option detects if there is a set of contiguous edges within a solid or mesh object, 
or within or between surfaces. The chain may either be open or closed and is available in the 
SURFPATCH, SURFBLEND, MESHCAP, and FILLETEDGE commands. 
The Chain option within the FILLETEDGE command identifies and fillets edges that have continuity. For 
example, the part below on the left does not have rounded corners so the fillet operation is limited to the 
selected edge. The part on the right, however, has rounded corners enabling the Chain option to select and 
fillet all the continuous edges.
