How do I modify drawing templates at a later time?

Migrating and Customizing > Migrating and Customizing Issues >

Drawing template (DWT) files are no different than a drawing (DWG) file, with the exception of its file extension. Once a DWT file is opened, you can modify named objects such as layers, and text and dimension styles just as you would in a drawing. You open a DWT file with the OPEN command.

Procedure

To open a drawing template (DWT) file

Click the Application menu button Open.
In the Select File dialog box, select Drawing Template (*.dwt) from the Files of Type drop-down list.
Browse to and select the drawing template (DWT) file you want to modify.
Click Open.
Make the desired changes to the DWT file.
Click the Application menu button Save.
