About Measurements and Fabrication Tolerances

Whether submitting your own CAD file or a file from Designer (which provides dimensions for the metal components only), tolerances for finishes, cutouts, profiles, bends, and welding must be considered.
For details please see Fabrication Tolerances.
For a quick reference, download the Fabrication Tolerances Diagram.

The following documents also have important detail on specifying measurements for specific designs:

• Designing enclosures for motherboard-based systems
  
• Creating an enclosure to mount a PCB
  
• Selecting height of self-clinching fasteners based on material thickness
  
  

When using Designer, if you need a part that is not stocked, you can add a similar part for purposes of placement and length, and use the Note tool to specify the exact part that you really want. Non-stocked parts incur additional time, and you will be informed of that cost.
