The bottom of the “CAD Resources for VEX IQ” page(found here) on the knowledge base still shows a link to the Slapshot field CAD
Seems issue has been fixed
1 small note for anyone looking to import the entire CAD library(found on same page) into Fusion360. The “3x12 Girder Plate; 2x8 2x Offset Trapezoid” will need to be renamed to remove the semicolon as a semicolon is a forbidden character in Fusion filenames.
