Finite is one of the extent options for protrusion and cutout features. The following examples show the effect of using Finite for protrusions.
The first figure shows a closed profile extruded a finite distance from a part face, to one side of the profile plane.
The next figure shows a profile extruded a finite distance from a profile drawn in a plane perpendicular to the part. The profile is extruded to one side of the profile plane.
The next figure shows an open profile extruded symmetrically a finite distance on both sides of the profile. Notice that the Distance value is the total extent of the extrusion. Notice also that the ends of the profile are extended to meet the curvature of the part face.
The next figure shows how you can use an open profile protrusion to lift a portion of a part face. Sketch the profile on the face and then give use a finite extent distance for the lift. This is useful for constructing lips, feet, and other small protrusions along the outside edges of a part.
The next figure shows an open profile extruded to lift a portion of a face in the corner of a part.
