Production systems evolve to accommodate new and redesigned products. These changes are planned offline in virtual tools, reduce disturbances on ongoing production. Offline planning requires models that correctly represent reality. Most "as-designed" suffer from geometrical errors stemming deployment alterations. Such often discovered late the next change process or during installation, making corrections expensive. Having geometry assured production eliminate one source of error system...
