Click Add to add a style to the new category. Repeat to add additional styles.

7

To delete a category, right-click the category name in the left pane and click Purge.

NOTE

Deleting a category deletes the category and the references to the styles within the category.

It does not delete the actual styles.

Customizing Device Content

This section provides information on several conversion tools you can use to create device content.

For information on creating style-based content manually, see 

Workflow for Creating Style-Based Content

on page 599.

Converting Blocks and Parts to Devices

You can convert a single AutoCAD block, MvBlock, or MvPart to a device. Because devices are style-based
objects, and all style-based objects are defined by styles, this creates an associated device style as well.

To convert a block or part to a device

1

Select the AutoCAD block, MvBlock, or MvPart to convert to a device.

You can select a block or part in the current drawing or in one of its 

referenced drawings

 (xrefs).

2

Click Equipment tab

 ➤ 

Modify panel

 ➤ 

Convert To Device

 .

3

In the Device Convert - Behavior dialog, for Name, enter a unique name for the device, and for
Type, select the type of device to create.

TIP

The Type property of the device can be useful when you need to modify multiple objects of the

same type. You can quickly select all of the objects in the drawing, and then use a modify command,
such as LIGHTINGMODIFY, to modify only the objects of a specific type.

4

For Layer Key, click 

 to open the Select Layer Key dialog, select the layer key to associate

with the device, and click OK.
