It really helps to have a naming system for named objects, including:

Blocks Dimension styles Text styles Multileader styles Table styles Layers Linetypes UCSs (User Coordinate Systems) Viewports (viewport configurations) Views

But sometimes you need to change their names.Maybe you made a mistake or you’re working on a drawing created by someone else and […]

Old AutoCAD drawings? It’s time to update them!

Tweet

Do you have REALLY old AutoCAD drawings? Many people keep drawings for years and years. But some older settings may make editing difficult. Here are some ideas for updating your old drawings.

Blocks without previews or descriptions

In older versions of AutoCAD, blocks didn’t have previews, like the kind you now see in the […]

Slim down your drawings with the PURGE command

Tweet

Are your drawings bloated for no obvious reason? When you insert a block, is there a long list of blocks that aren’t in the drawing? Ditto for layers?

Then you need the PURGE command!

Yes, you want slim drawings

Definitions of blocks, layers, styles, and more that aren’t actually used in the drawing make […]

Reduce file size and eliminate unwanted drawing settings with the WBLOCK command

Tweet

Several people have asked about inexplicably large files.

Kerry Overall wrote me,

I’ve seen unusually large CAD .dwg files. I had the same problem when a colleague stumbled onto a solution that greatly helped me. Open the drawing….wblock, click on “Entire Drawing” and save it. I had a simple file that was 73mb and […]

Batch check multiple AutoCAD drawings against a standards file

Tweet

In a previous post, “Use a Standards file to bring an AutoCAD drawing into line,” I explained how to check a drawing for certain standards, such as layers. This process is important for maintaining drawing standards where you work.

But suppose you want to check standards for many drawings at once? You can, using […]

Fix problems with the way AutoCAD looks (the user interface)

Tweet

Recently, a reader of my book, AutoCAD 2013 Bible, was reading something I wrote about the ribbon. He undocked it. (You can do that by right-clicking at the very end, in the blank gray space and choosing Undock.) Then, he clicked the X on the ribbon, which closed it. (Of course, I never recommended […]

Get a list of all the objects in your drawing with DBLIST

Tweet

Have you ever done a ZOOM Extents and found objects way out there like stars in outer space? Or tried to delete a layer but found you couldn’t because there was an object on it — but you couldn’t find it?

When troubleshooting objects, you might find it useful to have a list […]

Keep track of what you’ve done with COPYHIST

Tweet

Thanks to Tommy Holden for this tip.

AutoCAD allows you to copy the command line history window to the clipboard by using the COPYHIST command. The command line history is the window just above the command line. This way you can keep track of previous commands already executed in case you want to:

Repeat […]

Troubleshooting problem drawings

Tweet

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 […]

How to stay up to date with AutoCAD

AutoCAD is a complex program and it’s crucial for your work. Obviously, the better you know how to use the program, the quicker and more accurate your drawings will be. This is where the importance of education comes in.

Education has two parts:

Learning more about the base AutoCAD features that you use, or […]
