Scope and common interpretation errors
For coordinating drawings and inspection methods, not a replacement for a complete GD&T standard.
Free placement, light restraint and installed stretch are different states. Locating force changes results; an unspecified restraint can make a report irreproducible.
Turn the review into recorded checks
| Step | Action and evidence |
|---|---|
| 1 · Start from function | Identify key sealing, locating and connecting features. |
| 2 · Agree the measurement state | Specify support surfaces, locating points and allowed contact without hand-straightening. |
| 3 · Repeat measurements jointly | Compare the same batch with the same method before agreeing tolerances and decision rules. |
A comparison to avoid misinterpretation
If a shaped gasket must be stretched onto a fixture to measure hole spacing, label it a restrained-state dimension and separately verify that such stretch is permitted in the assembly.
Frequently asked question
Do more drawing dimensions always simplify acceptance?
Functional relevance and repeatability matter more; avoid overconstraining noncritical features.
