A fixture pin assembly for presenting a pin in a specified location and orientation to provide positioning or dimensional verification for a target part. The fixture pin assembly comprises a block, a pin, and an actuator set. The block includes a plurality of holes on a plurality of surfaces to attach directly or indirectly to mating bushings, pins, and actuation component sets. Pin and bushing act in combination to present a pin which is fixed or may allow motion in specified directions. Actuation component set provides motion control of the pin to either fix the location in longitudinal direction or allow longitudinal motion with or without springs to impart force either rearward or forward. A cable actuation system provides for remote release functionality of pin. Entire system design is configurable and interchangeable to provide cost-effective and space-effective implementation.
