Thus, when I add the cad file it does not spatially align with my other layers. Does anyone know the solution to this problem.</SPAN></BODY></HTML> Thu, 31 Jan 2013 15:05:15 GMT https://community.esri.com/t5/data-management-questions/adding-cad-data-with-no-spatial-reference-into-arc/m-p/633109#M35773 RogerMiranda 2013-01-31T15:05:15Z Re: Adding CAD data with no spatial reference into arc map. https://community.esri.com/t5/data-management-questions/adding-cad-data-with-no-spatial-reference-into-arc/m-p/633110#M35774 <HTML><HEAD></HEAD><BODY><SPAN>If it's in a 'known' coordinate system like a UTM zone, you can define its coordinate system with the Define Projection tool or its property page in ArcCatalog.
