Annotation

A text note or a symbol that adds specific design intent to a part, assembly, or drawing. Specific types of annotations include note, hole callout, surface finish symbol, datum feature symbol, datum target, geometric tolerance symbol, weld symbol, balloon, and stacked balloon. Annotations that apply only to drawings include center mark, annotation centerline, area hatch, and block.

Assembly

A document in which parts, features, and other assemblies (sub-assemblies) are mated together. The parts and sub-assemblies exist in documents separate from the assembly. For example, in an assembly, a piston can be mated to other parts, such as a connecting rod or cylinder. This new assembly can then be used as a sub-assembly in an assembly of an engine. The extention for a new Solidworks assembly file name is .SLDASM.

Axis

A straight line that can be used to create model geometry, features, or patterns. An axis can be made in a number of different ways, including using the intersection of two planes.

Balloon

Labels parts in an assembly, typically including item numbers and quantity. In drawings, the item numbers are related to rows in a bill of materials (BOM)

Base

The first solid feature of a part.

Bill of Materials

A table inserted into a drawing to keep a record of the parts used in an assembly (BOM).

Broken-Out Section

A drawing view that exposes inner details of a drawing view by removing material from a closed profile, usually a spline.

Center Mark

A cross that marks the center of a circle or arc.

Centerline

A centerline marks, in phantom font, an axis of symmetry in a sketch or drawing.

Chamfer

Bevels a selected edge or vertex. You can apply chamfers to both sketches and features.

Closed Profile

Also called a closed contour, it is a sketch or sketch entity with no exposed endpoints; for example, a circle or polygon.

Component

Any part or sub-assembly within an assembly.

Coordinate System

A system of planes used to assign Cartesian coordinates to features, parts, and assemblies. Part and assembly documents contain default coordinate systems; other coordinate systems can be defined with reference geometry. Coordinate systems can be used with measurement tools and for exporting documents to other file formats.

Cut

A feature that removes material from a part by such actions as extrude, revolve, loft, sweep, thicken, cavity, and so on.

Degrees of Freedom

Geometry that is not defined by dimensions or relations is free to move. In 2D sketches, there are three degrees of freedom: movement along the X and Y axes, and rotation about the Z axis (the axis normal to the sketch plane). In 3D sketches and in assemblies, there are six degrees of freedom: movement along the X, Y, and Z axes, and rotation about the X, Y, and Z axes.

Design Library

Located in the Task Pane, the Design Library provides a central location for reusable elements such as parts, assemblies, and so on.

Detail View

A portion of a larger view, usually at a larger scale than the original view.

Dimension Line

A linear dimension line references the dimension text to extension lines indicating the entity being measured. An angular dimension line references the dimension text directly to the measured object.

Face

A selectable area (planar or otherwise) of a model or surface with boundaries that help define the shape of the model or surface. For example, a rectangular solid has six faces.

Feature

An individual shape that, combined with other features, makes up a part or assembly. Some features, such as bosses and cuts, originate as sketches. Other features, such as shells and fillets, modify a feature's geometry. However, ot all features have associated geometry. Features are always listed in the FeatureManager design tree.

Fillet

An internal rounding of a corner or edge in a sketch, or an edge on a surface or solid.

Fully Defined

A sketch where all the lines and curves in the sketch, and their positions, are described by dimensions or relations, or both, and cannot be moved. Fully defined sketch entities are shown in black.

HLR (hidden lines removed)

A view mode in which all edges of the model that are not visible from the current view angle are removed from the display.

HLV (hidden lines visible)

A view mode in which all edges of the model that are not visible from the current view angle are shown in gray or dashed.

Import

Open files from other CAD software applications into a SolidWorks document.

Leader

A solid line from an annotation (note, dimension, and so on) to a referenced feature.

Library Feature

Mirror

(1) A mirror feature is a copy of a selected feature, mirrored about a plane or planar face. (2) A mirror sketch entity is a copy of a selected sketch entity that is mirrored about a centerline. If the original feature or sketch is modified, the mirrored copy is updated to reflect the change.

Model

3D solid geometry in a part of assembly document. If a part or assembly document contains multiple configurations, each configuration is a separate model.

Model Dimension

A dimension specified in a sketch or a feature in a part or assembly document that defines some entity in a 3D model.

Model Item

A characteristic or dimension of feature geometry that can be used in detail drawings.

Model View

A drawing view of a part or assembly.

Open Profile

Also called an open contour, it is a sketch or sketch entity with endpoints exposed. For example, a U-shaped profile is open.

Origin

The model origin appears as three gray arrows tand represents the (0,0,0) coordinate of the model. When a sketch is active, a sketch origin appears in red and represents the (0,0,0) coordinate of the sketch. Dimensions and relations can be added to the model origin, but not to a sketch origin.

Over Defined

A sketch is over defined when dimensions or relations are either in conflict or redundant.

Part

Plane

Flat construction geometry. Planes can be used for a 2D sketch, section view of a model, a neutral plane in a draft feature, and others.

Point

A singular location in a sketch, or a projection into a sketch at a single location of an external entity (origin, vertex, axis, or point in an external sketch.)

Profile

A sketch entity used to create a feature (such as a loft) or a drawing view (such as a detail view). A profile can be open (such as a U shape or open spline) or closed (such as a circle or closed spline).

Rebuild

Tool that updates (or regenerates) the document with any changes made since the last time the model was rebuilt. Rebuild is typically used after changing a model dimension.

Referenced Document

Any document that is referenced by another, typically part documents associated with an assembly or drawing documents associated with part or assembly documents.

Relation

Another term for profile in sweeps.

Section Line

A line or centerline sketched in a drawing view to create a section view.

Section View

A section view (or section cut) is (1) a part or assembly view cut by a plane, or (2) a drawing view is created by cutting another drawing view with a section line.

Sketch

A collection of lines and other 2D objects on a plane or face that forms the basis for a feature such as a base or a boss. A 3D sketch is non-planar and can be used to guide a sweep or loft, for example.

SmartMates

Solid Sweep

A cut sweep created by moving a tool body along a path to cut out 3D material from a model.

Standard 3 Views

The three orthographic views (front, right, and top) that are often the basis of a drawing.

Sub-assembly

An assembly document that is part of a larger assembly. For example, the steering mechanism of a car is a sub-assembly of the car.

Suppress

Removes an entity from the display and from any calculations in which it is involved. You can suppress features, assembly components, and so on. Suppressing an entity does not delete the entity; you can unsuppress the entity to restore it.

Surface

A zero-thickness planar or 3D entity with edge boundaries. Surfaces are often used to create solid features. Reference surfaces can be used to modify solid features.

Sweep

Creates a base, boss, cut or surface feature by moving a profile (section) along a path. For cut-sweeps, you can create solid sweeps by moving a tool body along a path.

Tangent Arc
