A part drawing gives dimensions, but it may not fully describe how the part should sit in a workstation. If the reference surfaces are left implicit, a clamp layout and an inspection layout can each seem reasonable while disagreeing about the actual position of the workpiece.
Distinguish the tasks
Location establishes the relationship between the workpiece and the station. Clamping keeps that relationship during the operation. Mark the locating faces, support points and clamp forces separately on a sketch. Then add the access needed for tools, sensors and the person loading the part.
Choose samples that show the range
A single ideal part may hide the difficult cases. Include the dimensional variation, surface condition and process stage that the fixture will encounter. If a surface cannot be touched, or a reference changes after assembly, record that condition at the start of the discussion.
Treat a changeover as a controlled setup
A modular base makes rearrangement possible; it does not remove the need for records. Keep the pin positions, spacer heights, clamp tips and loading order with the part revision. A top-view image with numbered components can make the arrangement easy to recognise, alongside the controlled dimensions.
Separate the concept from its verified limits
The FX240 platform in this catalogue demonstrates a regular hole grid and replaceable accessories. Actual forces, stiffness and positioning requirements still need to be defined and checked. A useful fixture brief makes those unresolved points visible before a component list becomes an order.
