them from the host file. They stay on the list of xrefs and can be
reloaded at any time with the Reload option. This option can be useful
when you're working with complex drawings that have many xrefs.

In this chapter, you externally referenced the site plan drawing into the cabin draw-
ing as an architect who was designing the project might have done. If you were the
architect, you might want to have several additional drawings. Try doing this:
1. Create several new drawings of furniture and a shed. Each object is
to have its own layer. Make more than one drawing for some of the
objects, such as two beds or tables.
2. Add digital images on their own layers that show real-world examples
of the furniture.
3. Externally reference all the furniture and shed drawings into the cabin
drawing.
4. Use the Layer States Manager, as covered in Chapter 6, to create layer
states for each combination of furniture.
Compare Reference types
Try using the files found in the RefTypes directory of this chapters download to
test out the Attachment and Overlay reference types. See what happens if you try
to create a circular reference by doing the following:
1. Open SQUARE.DWG , and load PENTAGON.DWG as an Attachment reference.
Also load CIRCLE.DWG as an Overlay reference.
Use an insertion point of 0,0 and scale of 1 for all xrefs in this
exercise.
2. Save SQUARE.DWG , and open PENTAGON.DWG .
3. Use the XREF command to load SQUARE.DWG.
4. Save and close the SQUARE.DWG , and open TRIANGLE.DWG .
5. Attach SQUARE.DWG to TRIANGLE.DWG as either an Attachment or
Overlay Reference Type.
