A
|
|
affinity |
An operation in which an element is transformed by
applying X, Y, Z affinity ratios with respect to a reference axis system. |
|
C
|
|
child |
A status defining the hierarchical relation between a
feature or element and another feature or element. |
|
constraint |
A geometric or dimension relation between two elements. |
|
E
|
|
extrapolate |
An operation in which an element is extended a specified
amount while respecting tangency or curvature conditions. Typically a
surface boundary can be selected for in order to extrapolate the surface a
specified length. |
|
extruded surface |
A surface that is obtained by extruding a profile along a
specified direction. |
|
F
|
|
feature |
A component of a part. |
|
fill surface |
A surface that is obtained by filling a closed boundary
that is made up from a number of segments. |
|
fillet |
A curved surface of a constant or variable radius that is
tangent to and joins two surfaces. Together these three surfaces form
either an inner or outer corner. |
|
G
|
|
geometrical feature set |
A geometrical set, an ordered geometrical set, a solid
body or an hybrid body. |
|
guiding curve |
A curve, intersecting with a profile, and along which this
profile is swept. See also spine. |
|
J
|
|
join |
An operation in which adjacent curves or adjacent curves
can be assembled to make up one element. |
|
M
|
|
multi-section surface |
A surface that is obtained by sweeping two or more planar
section curves along a spine, which may be automatically computed or
user-defined. The surface can be made to follow one or more guide curves. |
|
O
|
|
offset surface |
A surface that is obtained by offsetting an existing
surface a specified distance. |
|
P
|
|
parent |
A status defining the hierarchical relation between a
feature or element and another feature or element. |
|
part |
A 3D entity obtained by combining different features. It
is the content of a CATPart document. |
|
part body |
A component of a part made of one or several features.
|
|
profile |
An open or closed shape including arcs and lines. |
|
R
|
|
revolution surface |
A surface that is obtained by revolving a profile around
an axis. |
|
rotate |
An operation in which an element is rotated by a specified
angle about an given axis. |
|
S
|
|
scaling |
An operation that resizes an element to a percentage of
its initial size. |
|
sketch |
A set of geometric elements created in the Sketcher
workbench. For instance, a sketch may include a profile, construction lines
and points. |
|
spine |
A curve which normal planes are used to position a profile
when creating a surface (lofted or swept surface for example). The profile
does not necessarily intersect with this spine. See also
guiding curve. |
|
split |
An operation in which one element is cut by another
element. |
|
swept surface |
A surface obtained by sweeping a profile in planes normal
to a spine curve while taking other user-defined parameters (such as guide
curves and reference elements) into account. |
|
symmetry |
An operation in which an element is transformed by means
of a mirror symmetry with respect to a reference plane, line or point. |
|
T
|
|
translate |
An operation in which an element is displaced a specified
distance along a given direction. |
|
trim |
An operation in which two element cut each other mutually. |
|
W
|
|
|
wireframe element |
Elements such as points, lines or curves that can be used
to represent the outline of a 3D object. |
