Tutorial: Create a command alias (keyboard shortcut)

Many people like to use the keyboard to enter commands, but some of the commands are long, hard to type, or difficult to remember. You can create keyboard shortcuts for commands, such as DL for DIMLINEAR or RVC for REVCLOUD.

AutoCAD comes with a large number of aliases already made for you. You edit the […]

How to control what you see by clipping xrefs and blocks

You can attach other drawings to the current drawing to facilitate the drawing process. For example, you can attach a floor plan to a drawing of an electrical layout to make sure that you put the outlets in the right location. These other drawings are called external references, or xrefs.

Sometimes, xrefs can be large. […]

Troubleshooting problem drawings

The most obvious problem is that you can’t open a drawing. Here are some techniques to try:

Rename the drawing’s BAK (backup) file by changing its filename extension to .dwg and see if you can open that. Find any temporary files (auto.sv$ by default) and rename them with a DWG extension and try to open […]

Replace one block with another

I received a question about how to replace one block with another block. Replacing blocks is useful for 3 reasons:

To create multiple versions of a drawing, each with a different block. For example, you could try out a floor plan with different desks. When your company replaces one part with another part If your […]

Remove duplicate and overlapping objects

Duplicate and overlapping objects waste ink and mean that your drawing isn’t accurate. However, often, they’re invisible.

The OVERKILL command, part of Express Tools, can help. This command deletes duplicate objects and goes further to combine overlapping lines and arcs. However, it’s not on the menu, toolbar, or ribbon, so you have to type it […]

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 […]

How to rotate the crosshairs and other techniques for drawing at an angle

Need to create a drawing at an angle? AutoCAD offers several options.

Use polar tracking to guide you

Right-click the POLAR button on the Status bar and choose Settings or click its down arrow and choose Tracking Settings. Set the angles you want and click OK. For example, a 45° angle will display tracking guides […]

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:

Break objects quickly in AutoCAD

Michael Tabacinic sent me this e-mail:

“First off, I’d like to say, love your blog and love your tips; So helpful! Especially the last one; coincidentally, I had been asking our CAD manager for the past three weeks if there was a way to give the “Break at Point” command (^C^C_break \_f \@ ) an […]

Manage layers with LAYWALK

Do you need to know which objects are on which layers? Count your layers? Hide objects on other layers? Layer Walk (the LAYWALK) command does all this and more. It was once part of Express Tools, but has become part of core AutoCAD.

Layer Walk is quite a powerhouse and pulls together capabilities from several […]
