I turned the Collar on, set the Ecom color to yellow for visibility, and then aligned the 2D and 3D pieces so the shape and sew line are correct, especially for large and production sizes. I copied base and collar symbols into the right layers, extracted inside to inside and outside to outside from the technical sketch, then deleted the technical sketch layer properly. I saved and closed everything after QC to confirm it looks correct. No action is specifically requested from you.
