GD&T Symbol Guide
Multiple Identical Features
Uses a count plus X to apply one dimension or requirement to repeated identical features.
Definition
The #X designator prevents redundant dimensions when the same requirement applies to multiple identical features.
The number before X is the quantity of repeated features covered by the dimension or callout.
Application
Use it for repeated holes, chamfers, radii, surfaces, or pattern features.
Use continuous feature instead when separated surfaces are intended to be controlled as one combined feature.
Multiple Identical Features Drawing Use
Multiple Identical Features is read with the adjacent dimension, note, or feature control frame so inspection uses the intended feature definition.
3D Tolerance Zone
This modifier changes how a related dimension, note, or feature control frame is interpreted.
Inspection Method
Read the symbol with the attached dimension, note, or feature control frame before evaluating the feature.
Verify the controlled feature using the drawing's stated limits, datum setup, and any special notes tied to the symbol.
Worked Read: Multiple Identical Features
A drawing includes the Multiple Identical Features symbol with a related feature requirement.
Identify
8X
Recognize the Multiple Identical Features symbol and the feature it modifies.
Read
Adjacent value
Use the attached dimension, note, or frame cells as the controlling requirement.
Inspect
Per drawing
Measure the named feature using the specified interpretation rather than assuming a generic size check.
Multiple Identical Features clarifies how the feature is defined so the drawing and inspection method stay aligned.
Comparison Table
| Item | Controls | Typical Placement |
|---|---|---|
| Multiple Identical Features | Requirement interpretation | Next to a dimension, note, or frame |
| GD&T control | Geometric variation | Feature control frame |
| Datum reference | Measurement setup | Datum feature or frame cell |
Notes
This page is part of the drawing-symbol reference set rather than a standalone geometric tolerance category.
When the symbol modifies a feature control frame, read it together with the tolerance value and datum references.
