training | Profile of a line symbol
of a line describes a tolerance zone around any curved profile
or shape. It is usually called out on a profile surface, like
a radius on a part, it specify how much that cross-section could
vary from a true curved radius.
of a line can be measured using a dial gauge with some holding
fixtures along the specific cross-section area. Because of
the cross-sections of the feature, the measurement points
can be specified on the drawing. Profile is usually measured
using a CMM for more complex geometric.
