CAD Resources

SPU, SDOT and Seattle Parks & Recreation Department only support 2023 Autodesk products. Consultants are required to use 2023 Autodesk software and meet the requirements as described in the SPU/SDOT CAD Requirements for Consultants document, linked below.

Existing consultant contracts already in place are not required to upgrade from 2020 to the 2023 release. However, we encourage you to upgrade with us so that we may better support your CAD related needs moving forward.

Any new consultant contracts, or work authorizations signed March 2023 or thereafter will be required to use the 2023 release.

We have created resources on this page for your use, such as CAD support files and the CAD Manual. Should you have any problems or questions using these files or our CAD Standards in general, please contact the SPU CAD Support Team at SPU_CADSupport@Seattle.gov.
