In theyrevious , you removed objects from the Kitchen block simply by using the Erase command. You can also move objects from a block or into the current without actually erasing it. To do this, select Modify :> In-Place Xref and Block Edit >Remove From Wor.king Set. This removes the object from the block or Xref without erasing it. Likewise, you can add new objects to the block or Xref using select Modify :> In-Place Xref and Block Edit >Add to Working Set.Both of these options are the Refset command with different options applied. To see how Refset works, try the following exercise.

1 Close the Unitxref file.
2 In the Planxref file, zoom into the kitchenette to get a view similar to Figure 6.17.
3 Choose Modify :> In-Place Xref and Block Edit >Edit Reference.
4 Click the kitchenette.
5 Click the Kitchen listing in the Reference Edit dialog box, then click OK.
6 Select the entire kitchenette again.
7 Use the Move tool to move the two right-hand burners just to the right of the kitchenette, as shown in Figure 6.17.
8. Click the Transfer (Remove) Objects from the Refedit Working Set button in the Refedit toolbar, or select Modify :>- In-Place Xref and Block Edit > Remove From Working Set.
9. Select the two burners you just moved, then press.

Notice that the burners become grayer to show that they are now removed from the working set. They remain as part of the Planxref drawing, but they are no longer part of the Kitchen block.

Now add a rectangle to the Kitchen block in place of ” l’ burners.

1. Draw a 7″ by 16″ (18cm by 40nn)  burners,

2. Select the rectangle you drew in place, press.1.
3. Click Save Back Changes to Reference Toolan the R,·ff’dlt toolbar or select Modify :> In-Place Xref and Block Edit >Save Reference Edits.
4. Zoom out enough to see the other units in the drawing

Notice that now you see that the burners have been replaced by the rectangle in all the other Xref units. The burners you moved are still there in the lower-right c.<~rner unit, but they have been removed from all of the Xrefs. It is as if you had extracted them from the block and placed them in the Plan drawing. Once you start the Refedit command, any new objects that you create are added to the working set automatically; until you save your reference edits. When you drew the rectangle in step 1, for example, it was automatically included in the working set, which is the set of objects included in the block or Xref you are currently working on. You didn’t have to specifically add it to the ‘ vorking set. If you want to include existing objects in the working set, use the Modify :> In-Place Xref and Block Edit> Add to Working Set option, or select it from t!’-,(:Refedit toolbar You’ve completed the exercises in this chapter so you can exit AutoCAD without saving these changes.

If You Want to Experiment

If you’d like to see  block sub-trtution works, try doing the in figure  It shows how quickly you  ‘ that- configuration of a ealry  by careful use of block substitution. As you work through the exercise, keep in
mind that some planning is required to use blocks in this way. If you know that you will have to try various configurations in a drawing, plan to set up files to accommodate them.

You might also want to try the exercise using Xrefs instead of inserting files as blocks. Once you’ve attached the Xref, try substituting the Tabl Xref with the Tab2 Xref by using the Browse button in:the External Reference dialog box. Highlight Tabl in the list of Xrefs, and then click Browse and select Tab2. The current file still calls the Xref Tab1 by its original name, but instead loads Tab2 in its place.

By now, you may be anxious to see how your drawings look on paper ..In the next chapter, you will explore the use of AutoCAD’s printing and plotting commands .
