I have a few finished drawing assemblies. I noticed that somehow I selected a fine thread during creation instead of course. When I try and go back and edit the smart fastener to course it keeps reverting back to fine thread. Example: Somehow I made a mistake when first creating the assembly and selected a 3/4"-16 bolt. After making the drawing I caught my mistake and went back into the assembly and edited that smart fastener to 3/4-10. As soon as I hit the green check mark it reverts back to the original 3/4-16 fastener. How do I fix this?
