Geometric Tolerance Types Summary
| Symbol | Ime | Category | Datum? | Zone |
|---|---|---|---|---|
| ⏥ | Flatness | Form | No | Two parallel planes |
| ⏤ | Straightness | Form | No | Two parallel lines / cylinder |
| ○ | Circularity | Form | No | Annular ring |
| ⌭ | Cylindricity | Form | No | Two coaxial cylinders |
| ⊥ | Perpendicularity | Orientation | Yes | Two parallel planes / cylinder |
| ∠ | Angularity | Orientation | Yes | Two parallel planes |
| ∥ | Parallelism | Orientation | Yes | Two parallel planes / cylinder |
| ⌖ | Position | Location | Yes | Cylindrical / between planes |
| ◎ | Concentricity | Location | Yes | Cylindrical |
| ↗ | Kružno odstupanje od ose | Runout | Yes | Two coaxial circles |
| ↗↗ | Total Runout | Runout | Yes | Two coaxial cylinders |
| ⌒ | Profile of a Line | Profil | Optional | Two equidistant curves |
| ⌓ | Profile of a Surface | Profil | Optional | Two equidistant surfaces |
Tip: Form tolerances (flatness, straightness, circularity, cylindricity) never require a datum reference. Orientation and location tolerances always require at least one datum.
