NOTE:
The figures included in this standard are merely intended to illustrate how annotations shall or can be
made in 3-D environment. They are not intended as recommendations when choosing type of tolerance, size of
tolerance zone, etc. Nor are the illustrations intended to show the complete set of requirements needed to define
a part.
2 Terms and definitions
For the purposes of this standard, the following terms and definitions apply:
annotation
dimension(s), tolerance(s), note(s), text or symbol(s) visible without any manual or external manipulation
annotation plane
conceptual plane containing
annotation
NOTE 1
−
It is desirable that annotation planes intersect or coincide with a model feature.
NOTE 2
−
The plane is “conceptual” because it is not physically shown as geometry on the model, but is provided to
replace the drawing media.
associated entities
portion of a product definition to which
annotation
pertains
associated group
user-defined set of related
digital elements
associativity
established relationship between
digital elements
attribute
dimension, tolerance, note, text or symbol required to complete the product definition or model feature of the
product that is not visible but available upon
querying
the model
digital shape model (DSM)
portion of the data set that contains
model geometry
and
supplemental geometry
NOTE 1
−
In ISO 16792:2006, the term
design model
is used to denote this concept.
digital element
geometric element
,
model feature
, group of model features,
annotation
,
associated group
or
attribute
that exists in
a data set
model geometry
geometric elements in product definition data which represent a designed part
geometric element
graphic entity used in a data set
EXAMPLES Representation of geometric feature as defined in ISO 14660-1, representation of model coordinate
system, or representation of crosshatching.
management data
data required for the release, control and storage of product-definition data as well as other relevant engineering
data
model
combination of
digital shape model
,
annotation
and
attributes
that describes a part
model feature
model geometry that represents a physical portion of a part
model value
numerical value derived by
querying
the model that quantifies the form and spatial relationships of the geometry
composing a
digital shape mode
l or assembly of models to the precision (number of decimal places) of the
computer system
