I have a DriveWorksXpress model that I am modifying. The assembly that I am adding has a distance mate. When I try to import the mate into driveworksxpress, it imports as a feature, rather than a dimension. I am not sure why, as I have imported other distance mates as dimensions into the model in the past. It needs to be a dimension so I can define the distance based on user inputs. I think I must be missing something basic, but I cant figure it out. Any help or advice would be greatly appreciated. Let me know if you need any more details.
