The Constant Blend function can be used to round the selected edges of a solid body with a constant radius.
NOTE: If a blend operation were to fail, an error dialog appears through which you can elect to create the blend surfaces as sheet bodies. Once this is done, you can use surfacing tools to trim the blend surfaces to the adjacent surfaces of the proposed blend, once modifications have been made to the blend surfaces themselves.
Enter the radius of the blend in the Blend radius field.
