You are trying to add a second viewport within a larger one by creating a wipeout and putting the new viewport on top. However, the entities in the viewport are not showing. Using the command DRAWORDER to send the wipeout behind the new viewport does not work.
- Use VPCLIP command to adjust the shape and size of the larger viewport, being sure to allow enough space.
- Place the new viewport within the modified, larger viewpoint.
