The “Coordinate Drawings and Database” Command

Sunday, October 3rd, 2010

The “Coordinate Drawings and Database” command is used frequently in error situations to fix the problem and often to recover information that AutoCAD itself lost.

To coordinate your drawing, use these commands:

  • HVAC: “DM HVAC->Utilities->Coordinate Drawings and Database”
  • Electrical: “DM Electrical->Utilities->Coordinate Drawings and Database”
  • Plumbing: “DM Plumbing->Utilities->Coordinate Drawings and Database”

A “Coordinate” dialog will be displayed that lists all the drawings in your project. The current drawing will be highlighted. Typically, you will press OK to coordinate the current drawing. However, you can select multiple drawings and have the coordinate command run on multiple drawings at once.

The coordinate command looks at the drawing and the database and makes sure that all the information in each matches.

When you make changes to your drawing, these changes are immediately recorded in the database. They are not recorded in the drawing until you save. If AutoCAD crashes before you save, the database has newer and better information than the drawing does. Using the coordinate command, you both get them to match, and often can recover information that AutoCAD lost.

Changes to customization settings are not immediately reflected on the drawings. If you change your customization settings in the middle of a project, use the coordinate command to update your drawings.

There are other times where the coordinate command can fix errors in your project. It is never dangerous to run a coordinate. A backup of the current drawing and database are made before the coordinate is run in case something unexpected happens during the command. You are welcome to run the command at any time. We will often recommend that you run it in response to an error you report to us.

However, if you are frequently having to run the coordinate command, that is bad. It is a sign of something going wrong with the software. We encourage you to contact us in this case. Often, we can make a recommendation to your workflow to avoid the coordinate command, or work with you to locate a bug that we can fix so that you do not need to continue to run it.
