Key Terms
Te r m Definition
2D constraint Defines how a sketch can change shape or size. Geometric constraints control the
shape and relationships among sketch lines and arcs. Dimensional constraints
control the size of sketch geometry.
closed loop A polyline entity, or group of lines and arcs that form a closed shape. Closed loops
are used to create profile sketches.
closed profile A constrained sketch that is a cross section or boundary of a shape, such as an
extrusion, a revolved feature, or a swept feature.
construction geometry Any line or arc created with a noncontinuous linetype. Using construction
geometry in paths and profiles may mean fewer constraints and dimensions are
needed to control size and shape of symmetrical or geometrically consistent
sketches.
cut line Used to specify the path of a cross-section drawing view. Unlike a profile sketch,
the cut line sketch is not a closed loop. There are two types of cut line sketches—
offset and aligned.
feature An element of a parametric part model. You can create extruded features,
revolved features, loft features, and swept features using profiles and paths. You
can also create placed features like holes, chamfers, and fillets. You combine
features to create complete parametric part models.
nested loop A closed loop that lies within the boundary of another closed loop. Nested loops
are used to create more complex profile sketches.
open profile A profile created from one or more line segments sketched to form an open
shape. Open profiles are used in bend, rib, and thin wall features.
path sketch A constrained sketch that is a trajectory for a swept feature.
sketch A planar collection of points, lines, arcs, and polylines used to form a profile, path,
split line, break line, or cutting line. An unconstrained sketch contains geometry
and occasionally dimensions. A constrained sketch, such as a profile, path, split
line, cut line, or break line that contains “real” and construction geometry, and is
controlled by dimensions and geometric constraints.
sketch tolerance Tolerance setting that closes gaps smaller than the pickbox and snaps lines to
horizontal, vertical, parallel, or perpendicular.
split line A sketch, either open or closed, used to split a part into two distinct parts. Also
known as a parting line.
text sketch profile A profile created from a single line of text in a selected font and style. Text-based
profiles are used to emboss parts with text.
