Introduction

In this chapter, you will use the AutoCAD DesignCenter to copy layers and blocks (furniture) from one drawing to another. You will also make blocks that perform actions dynamically. Finally, you will use external reference commands that allow you to attach drawings to other drawings so that they appear in the primary drawing without inserting them.

EXERCISE 10-1 Reception Area Furniture Installation Plan Using the DesignCenter

When you have completed Exercise 10-1, your drawing will look similar to Figure 10-3 without dimensions.

Step 1. Use your workspace to make the following settings:

Use Block Editor to Make Dynamic Blocks

You can move part of an inserted dynamic block within the dynamic block (such as a chair within a chair-and-desk combination) without exploding the block. A dynamic inserted block can be changed without exploding it. A standard inserted block must be exploded before it can be changed. You can also change the size of the dynamic block as you work. For example, if the desk is needed in a variety of sizes, you can define it as a dynamic block that has a parameter (a feature) that allows the width, depth, or both to be changed without exploding the block or redefining it.

dynamic block: The user-defined collection of drawing objects that can be changed without exploding the block.

The Block Editor is used to create dynamic blocks. The Block Editor allows you to add the elements that make a block dynamic. You can create a block from scratch, or you can add dynamic features to an existing block.

Image

In the following part of this exercise you will redefine the existing woodgrain table as a dynamic block that can change size. You will add dynamic blocks of desk chairs that can be visible or invisible. You will also redefine the existing right-hung 36-in. door as a dynamic block that can flip from one side of the wall to the other. Start with the woodgrain table.

Step 27. Print Exercise 10-2 to scale.

EXERCISE 10-3 Attach an External Reference to an Office Plan

XATTACH (Attach External Reference)

Before you start the XATTACH command, your primary drawing must be open. When you activate the XATTACH command, the Select Reference File dialog box opens and allows you to select the drawing that you want to attach. When you select and open a drawing to be attached as an external reference to your primary drawing, the External Reference dialog box opens. The External Reference dialog box allows you to specify whether the xref will be an attachment or an overlay.

external reference (xref): A drawing file that is inserted into another drawing. External references have the advantage that the primary drawing always contains the most recent version of the external reference.

Attachment: An attached xref that is then attached to another drawing becomes a nested xref with all its features fully recognized.

Overlay: An overlay is ignored when the drawing on which it is overlaid is then attached as an xref to another drawing.

The XATTACH command allows you to attach an external reference (xref) (drawing) to a primary drawing. For each drawing, the data are stored in their own separate file. Any changes made to the external reference drawing are reflected in the primary drawing each time the primary drawing is loaded into the Drawing Editor.

There are three distinct advantages to using external references:

Image The primary drawing always contains the most recent version of the external reference.

Image There are no conflicts in layer names and other similar features (called named objects), such as linetypes, text styles, and block definitions. AutoCAD automatically inserts the drawing name of the xref and a slash (/) in front of the external reference layer name or other object name. For example, if the primary drawing and the external reference (named CHAIR) have a layer named Symbol, then the current drawing layer retains the name Symbol, and the external reference layer in the current drawing becomes CHAIR/symbol.

Image Drawing files are often much smaller.

External references are used, for example, for drawing a large furniture plan containing several different levels of office types, such as assistant, associate, manager, vice president, and president. Each office typical (furniture configuration used in the office) is attached to the current drawing as an external reference. When changes are made to the external reference drawing of the manager’s office (as a result of furniture substitution, for example), the change is reflected in each instance of a manager’s office in the primary large furniture plan when it is loaded into the Drawing Editor.

External Reference (XREF)

When you activate the XREF command, the External Reference palette appears. After an external reference has been attached to your drawing, you can right-click on the external reference drawing name to select from the following options:

Image

Attach...: Allows you to attach any drawing as an external reference to the current drawing. There is no limit to the number of external references that you can attach to your drawing. This is the same command as XATTACH.

Detach: Lets you remove unneeded external references from your drawing.

Reload: Allows you to update the current drawing with an external reference that has been changed since you began the current drawing. You do not have to exit the current drawing to update it with an external reference that you or someone else changed while in the current drawing.

Unload: Temporarily clears the external reference from the current drawing until the drawing is reloaded.

Bind...: The Insert option in the Bind dialog box creates a block of the external reference in the current drawing and erases any reference to it as an external reference. The Bind option binds the selected xref to the drawing and renames layers in a manner similar to that of the attached xref. This is the same command as XBIND.

XBIND

The XBIND (External Bind) command allows you to bind a selected subset of an external reference’s dependent symbols to the current drawing. For example, if you did not want to create a block of the entire external reference but wanted permanently to add only a dimension style of the external reference to the drawing, you could use XBIND.

Image

Features of External References

Following is a list of external reference features:

Image An external reference cannot be exploded.

Image An external reference can be changed into a block with the Bind... option and then exploded. The advantage of using the external reference is then lost. The Bind option would be used if you wanted to send a client a disk or file containing only the current drawing without including external references.

Image External references can be nested. That means that a current drawing containing external references can itself be used as an external reference on another current drawing. There is no limit to the number of drawings you can nest like this.

Image An xref icon appears in the lower right corner of the screen when xrefs are attached to a drawing.

Step 1. Draw the floor plan shown in Figure 10-30 and save it as CH10-EXERCISE3.

Chapter Summary

This chapter described the AutoCAD DesignCenter, Autodesk Seek, dynamic blocks, and external references. It showed you how to use the DesignCenter to take blocks, layers, linetypes, and text and dimension styles from any existing drawing using drag and drop and place them in the current drawing. It also showed you how to make external references and dynamic blocks. You will now be able to use these commands to make drawings quickly and efficiently.
