Glossary

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

extruded surface A surface that is obtained by extruding a profile along a specified direction.

F

feature A component of a part.

J

join An operation in which adjacent curves or adjacent curves can be joined.

M

multi-sections 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.
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.
