+                    You may specify the target fold angle of each crease using the edges_foldAngles field. 
+                    Note that fold angle is a number in degrees lying in the range [−180, 180]. 
+                    The fold angle is positive for valley folds, negative for mountain folds, and zero for flat, unassigned, and border folds.
+                    Accordingly, the sign of edges_foldAngle should match edges_assignment if both are specified.<br/><br/>
