LEADER
Creates a line that connects annotation to a feature.
TOLERANCE
Creates geometric tolerances contained in a feature control frame.
Material Conditions
Material conditions apply to features that can vary in size.
The second compartment contains the tolerance value. Depending on the
control type, the tolerance value is preceded by a diameter symbol and followed
by a material condition symbol.
Material conditions apply to features that can vary in size:
At maximum material condition (symbol M, also known as MMC), a feature
contains the maximum amount of material stated in the limits.
At MMC, a hole has minimum diameter, whereas a shaft has maximum
diameter.
At least material condition (symbol L, also known as LMC), a feature contains
the minimum amount of material stated in the limits.
At LMC, a hole has maximum diameter, whereas a shaft has minimum
diameter.
Regardless of feature size (symbol S, also known as RFS) means a feature can
be any size within the stated limits.
