method for making an additional feature by placing copies of a master feature on the model at a specified equal spacing. Arrays, (aka 'patterns') are normally created in the form of 1) rectangular patterns of 'instanced' features (based on X, Y, or Z offset distances) or 2) circular patterns (based on defining a reference axis and an angle to determine the rotational position for each 'instance'.
basic modeling planes
sketching planes on x-y, y-z, and x-z planes of a model
the first feature created for a part; this is usually a protrusion
a solid formed by a smooth transition between two or more profiles
an angled cut transition between two intersecting surfaces
a feature, also referred to as an 'instance', that is dependent upon the existence of a previously created feature
a geometric relationship, dimension, or equation that controls the size, shape and/or orientation of entities in a sketch or solid model
a measurement used to control the size or position of entities in a sketch, feature, or model.
a geometric relationship, such as coincidence, parallelism, perpendicularity, tangency, concentricity, or others, that are applied to geometric entities in a sketch or model to accurately control the precise geometric shape of a sketch or object.
constructive solid geometry (CSG)
a method used to build solid models from primitive shapes based on Boolean set theory
a feature created by the removal of solid volume from a model
a collection of information for a computer, and a method for interpretation of this information, from which the original model can be recreated
geometric entities, such as points, axes, and planes, that do not actually exist on the real part, but are used to help locate and define other features
double-sided (mirrored) extrusion
a solid formed by the extrusion of a profile in both directions from its sketching plane
extrude-to-surface (to next or to last)
an extrusion where the protrusion or cut begins on the sketching plane, and stops when it intersects a selected surface
a solid that is bounded by the surfaces swept out in space by a planar profile as it is pulled along a path perpendicular to the plane of the profile
a distinctive geometric shape on a solid part; a 3-dimensional geometric entity that exists to serve some function
feature-based solid modeler
feature-based solid modeler
listing of all the features of a solid model, in the order in which they were created, providing a "history" of the sequence of feature creation
a smooth transition of the internal edge created by two intersecting surfaces and tangent to both intersecting surfaces
After the base feature is created, form features (aka design features) on a part are created by adding or subtracting material. A form feature is a recognizable region or area on the part geometry that may have a specific function and/or method of manufacture.
constraint usually applied to a new sketch to fix the location and orientation of a sketch or feature in space
a 3D model that is bound by the surfaces swept out in space as a profile is pulled along a curved or non-linear path. Lofts may also be created through multiple cross sections. This operation may also be referred to as a swept surface or swept solid depending on the software package.
a feature that is created as a mirror image of a master feature
same as feature tree
parametric solid modeler
a solid modeling system that allows the user to vary the dimensions and other parameters of the model
a feature that is used in the creation of another feature which is called its child feature. Child features are also referred to as 'instances'.
the trajectory (aka 'spine' in CATIA) on which a profile is placed to create a swept solid
same as an array
one of a set of regular shapes such as a box, sphere or cylinder, that are used to build solid models with constructive solid geometry methods (CSG)
a planar sketch that is used to create a solid
a feature created by the addition of solid volume to a model
updating the profile or part to show its new shape after constraints are added or changed
a solid formed when a profile curve is rotated about an axis
constant thickness protrusions that extend predominantly from the surface of a part and are used to strengthen or stiffen the part
a smooth radius transition of the external edge created by two intersecting surfaces and tangent to both intersecting surfaces
a feature that removes most of the interior volume of a solid model, leaving a relatively thin wall of material that closely conforms to the outer surfaces of the original model
a collection of 2-dimensional entities typically located on the same reference plane
software facility used to create and edit sketches
plane where 2-dimensional sketches and profiles can be created
a polynomial curve that passes through multiple data points
a mathematical representation of a physical object that includes both the surfaces and the interior material, usually including a computer-based simulation that produces a visual display of an object as if it existed in 3- dimensions
the option for temporarily suppressing the visibility or 'not displaying' a selected feature
CAD generated model created to show a part as a collection of intersecting surfaces which bound a solid
a solid that is bound by the surfaces swept out in space as a profile is pulled along a path. This operation may also be referred to as a 'loft'.
the option for displaying a selected feature that has be suppressed
a point that is used to define the endpoint of an entity such as a line segment, or the intersection two geometric entities
small, thin protrusions that connect two or more thicker regions on a part
CAD model created using lines, arcs and other 2-dimensional entities to represent the edges of the part; surfaces or solid volumes are not defined
