Through Next is one of the extent options for protrusion and cutout features. The following examples show the effect of using Through Next for protrusions.

The first figure shows a closed profile extruded through next, to one side.

The next figure shows the same profile extruded through next, to the other side.

The next figure shows the same profile extruded through next, to both sides.

The next figure shows another example of a profile extruded through next. Notice how the profile is extended as far as necessary to form a closed intersection with the part, but does not extend past the intersection.

You can construct a through next protrusion using an open profile, as shown in the next figure.

For protrusions, the through next extent option must result in a feature that completely intersects the part. The next figure shows an invalid case for using through next. To create this type of protrusion, use the From/To or Finite extent option.
