Keep your own styles, layers & blocks at the top of the list

You’re always creating styles — text, dimension, etc. — layers, and blocks. But when you open the Layer Properties Manager or any other list with these items, they are alphabetized. Especially if you’re sharing drawings with others who add their own styles, layers, and blocks, what can you do to make it easier to find [...]

Chain dynamic blocks (AutoCAD 2006 and later)

Dynamic blocks, introduced in AutoCAD 2006, are very powerful, but sometimes they can get complicated. One of the more involved features of dynamic blocks is chaining. In this tip, I try to make chaining easy.

Sometimes, you want one action to execute a second action at the same time. If the relationship [...]

Working with Blocks: The BASE command, the Basepoint option, and the Basepoint parameter

Blocks and basepoints go hand-in-hand. Knowing how to work with basepoints can make your life much easier. It’s so frustrating to insert a block and have it disappear into outer space because the basepoint is in the wrong location!

The Basepoint option of the INSERT command

When you insert a block, a Basepoint option appears with the [...]

Extract data from objects in AutoCAD 2008 and later

One of the new features in AutoCAD 2008 is data extraction. This might make you think of block attributes and data connectivity, but it combines features of both. It’s both simple and powerful.

You start with the new DATAEXTRACTION command, or by starting the TABLE command and choosing the From Object Data in the [...]

Extract attributes and customize the database column headings

Attributes are labels that you apply to blocks. You can extract them to create a simple database that you can then view in Excel or place in your drawing as a table. You use the EATTEXT command.

When you use EATTEXT, the Attribute Extraction wizard starts. Page 3 of the wizard looks like this:

On the left, [...]

On which layers should you create blocks?

When you create blocks (also called symbols) to insert into a drawing, you need to consider what layer to use for the components that make up the blocks. Your choice depends on the results you want and you have four choices:

Component Properties

Insertion Results

On any layer (except 0); color, linetype & lineweight set [...]

Tutorial: Use fields to automatically label dynamic blocks

You can use fields (AutoCAD 2005 and later) to create automatic labels that provide information about objects.

I’ve covered aspects of this topic before. In “Tutorial: Display the area of an enclosed figure,” I show how to use fields to create a label that displays an area.

In “Tutorial: Create attributes,” I mention that you can use [...]

Follow these steps:

Open the Properties palette.
Click the Quick Select button to open the Quick Select dialog box.

Tutorial: Create attributes

Tutorial: Create attributes

Attributes are tags, or labels, for blocks. You can use attributes to add any text to a block. For example, attributes are often used to fill in the text in a title block.

By placing the attributes where you want them in the title block, you can facilitate the [...]
