GEOMETRIC SYMBOLS AND DEFINITIONS
Feature-Control FrameA specification box that shows a particular geometric characteristic (flatness, straightness,etc.) applied to a part feature and states the allowable tolerence. The feature’s tolerancemay be individual, or related to one or more datums. Any datum references and tolerancemodifiers are also shown.
Datum FeatureA flag which designates a physical featureof the part to be used as a reference tomeasure geometric characteristics of otherpart features.
Basic DimensionA box around any drawing dimensionmakes it a “basic” dimension, atheoretically exact value used as areference for measuring geometriccharacter istics and tolerances of other partfeatures.
Regardless of Feature SizeAbbreviation: RFS. A tolerance modifierthat applies the stated tight tolerance zoneunder all size conditions. RFS is generallyassumed if neither MMC nor LMC arestated.
Projected Tolerance ZoneAn additional specification box attachedunderneath a feature-control frame. Itextends the feature’s tolerance zonebeyond the part’s surface by the stateddistance, ensuring perpendicularity forproper alignment of mating parts.
Maximum Material ConditionAbbreviation: MMC. A tolerance modifierthat applies the stated tight tolerance zoneonly while the part theoretically containsthe maximum amount of materialpermitted within its dimensional limits (e.g.minimum hole diameters and maximumshaft diameters), allowing more variationunder normal conditions.
Least Material ConditionAbbreviation: LMC. A tolerance modifierthat applies the stated tight tolerance zoneonly while the part theoretically containsthe minimum amount of material permittedwithin its dimensional limits (e.g. maximumhole diameters and minimum shaftdiameters), allowing more variation undernormal conditions.
Cylindrical Tolerance ZoneThis symbol, commonly used to indicate adiameter dimension, also specifies acylindrically shaped toler ance zone in afeature-control frame.
Datum TargetsCallouts occasionally needed to designatespecific points, lines, or areas on an actualpart to be used to establish a theoreticaldatum feature.

GEOMETRIC CHARACTERISTICS
Each circular element of theindicated surface is allowed todeviate only the specifiedamount from its theoreticalform and orientation during360° rotation about thedesignated datum axis.
The entire indicated surface isallowed to deviate only thespecified amount from itstheoretical form and orientationduring 360° rotation about thedesignated datum axis.
If the indicated surface weresliced by any plane perpen -dicular to the designated datumaxis, every sliceʼs center ofarea must lie on the datumaxis, within the specifiedcylindrical tolerance zone(controls rotational balance).
The indicated featureʼs axismust be located within thespecified tolerance zone fromits true theoretical position,correctly oriented relative to thedesignated datum plane or axis.
