A multi-purpose platform unit that can form of a control or production fixture for use in the manufacturing industry. A base 2 having a longitudinal axis that is connectable to a permanent part of the control or production fixture. A first universal joint 4 is mounted on the base 2. A second universal joint 8 is pivotally mounted to the first joint 4 about a first pivot axis. A third universal joint 14 has a longitudinal axis and is pivotally mounted to the second joint 8 about a second pivot axis that is at right angles to the first pivot axis. The second and third universal joint 8 and 14 can be selectively locked to the first universal joint 4 and the second universal joint 8, respectively to position the longitudinal axis of the third universal joint 14 at a single or double compound angle with respect to the longitudinal axis of the base 2. A support plate 16 can be rotatably mounted on the third universal joint 14 for a device such as a tool, a clamp or a coordinate measuring machine.
