CAD Resources

The resources listed are for CAD users in Seattle Public Utilities (SPU) and Seattle Department of Transportation (SDOT), as well as consultants who are working on projects for SPU or SDOT.

We put together these supporting files and the CAD Manual in an effort to provide as much assistance as possible to the users. Since there are many ways to configure AutoCAD, we also tried to make the files as generic as possible. Should you have any problems or questions using these files or our CAD Standards in general, please contact the SPU CAD Support Team at
