How do you design a fixture knowing the product may be modified by the product engineers?
When designing a weld fixture, or jig as some people call them, it is important to remember that things can change. Machine designers need to think ahead and have a standard procedure to follow that will reduce errors and costs in the case of a product change. Changes can occur during or after the fixture has been designed.
Often times the product design team is on a tight schedule to begin production of the new product. They may hand it over to the manufacturing engineers before all the quirks are ironed out of it. They may still be producing and working with the prototypes, but they need to start getting the factory ready for production.

Manufacturing Engineers, what standard method of 3D model component location do YOU follow to help you in the event that product changes are made?
