When you create a sheet metal part as a base flange or lofted bend (with
the Bent
Manufacturing Method), you can specify a
symmetrical thickness that adds an equal amount of material to both sides of the
sketch.
Symmetrical thickness helps you create sheet
metal parts from
sketches to help achieve equal bend radii for upward and downward bends.
In
the image above, Symmetric is cleared for the
example on the left and selected for the example on the right.
In the Base
Flange or Lofted Bends
PropertyManager, under Sheet Metal Parameters,
select Symmetric.
