32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Extrude closed profile
- A closed sketch profile is required to create a solid extrusion. Open profiles produce surface bodies unless the extrusion is set to match an existing face.
- Revolve axis rule
- The revolve axis must lie in the same plane as the profile. If the profile crosses the axis, the resulting solid self-intersects and the feature fails.
- Hole termination types
- Hole features offer To Next, Through All, and Distance terminations. To Next stops at the first face; Through All passes through the entire part; Distance uses a numeric depth.
- Variable radius fillet
- A variable-radius fillet assigns a different radius at each point along the selected edge, unlike a constant-radius fillet which uses one value for the whole edge.
- Chamfer distance-angle
- A distance-angle chamfer uses one distance and one angle to define the cut. Distance-distance requires two distances; equal-distance is the default chamfer type.
- Shell feature
- Shell removes selected faces and offsets the remaining faces inward by a thickness. Selecting no faces creates a hollow closed body with uniform wall thickness.
- Loft sections
- A loft requires two or more section profiles. Rails or a centerline constrain the shape between sections. Closed Loop joins the first and last sections into a continuous surface.
- Model vs user parameters
- Model parameters (d0, d1, etc.) are created automatically by features. User parameters are defined in the Parameters dialog and can drive multiple dimensions across features.
- Assembly constraints
- Mate, Angle, Tangent, Insert, and Symmetry constraints each remove degrees of freedom from a component. A component with all six DOF removed is fully constrained.
- Joint command types
- The Joint command offers Rigid, Rotational, Sliding, Cylindrical, Planar, Ball, and Welding joints. Joints replace legacy constraints for new assembly design.
- BOM structure types
- Bill of Materials structures include Normal, Phantom, Reference, and Purchased. The structure is set per component and determines how it appears in the parts list.
- Flexible subassembly
- A subassembly set to Flexible allows its components to move within the parent assembly. Rigid subassemblies move as a single unit and cannot articulate internally.
- Interference analysis
- Analyze Interference compares selected components and reports overlapping volumes. It can create a new part representing the interference region for further inspection.
- Assembly pattern associativity
- An associative assembly pattern follows changes to the source component pattern. A non-associative pattern does not update when the source pattern changes.
- Mate constraint limits
- A Mate constraint can include a maximum and minimum offset, enabling movement within a defined range rather than a fixed position.
- Base view placement
- A base view must be placed first on a drawing sheet. Projected, section, detail, and auxiliary views are derived from it and inherit its orientation and scale.
- Section view requirement
- A section view requires a sketch line or an existing view boundary to define the cutting plane. The section depth and direction are set in the Section View dialog.
- Detail view boundary
- A detail view uses a circular or rectangular boundary around a region of a parent view. Its scale can be independent, and the label uses the detail letter.
- Auxiliary view projection
- An auxiliary view is projected perpendicular to a selected edge or line. It shows inclined faces true size and is derived from an existing view.
- Break view styles
- Break view styles include straight, jagged, and structural. The gap size and break style are configured in the drawing style and applied to the view.
- Parts list source
- A parts list is placed from a base view of an assembly and reads the assembly BOM. Item numbers can be renumbered or set to static values.
- Balloon attachment
- A balloon attaches to a component in a view. The leader termination can be a dot, arrow, or none, and the balloon can attach to a parts-list item.
- Dimension style override
- Overriding a dimension changes its appearance without altering the style. The override is shown in the browser and can be cleared to restore the style default.
- Drawing resources
- Title blocks, borders, and sheet formats are stored in the drawing template. Sheet size and orientation are set per sheet in the Sheet Setup dialog.
- Sheet metal style
- The Sheet Metal Style sets thickness, bend radius, and relief shape. These defaults drive flat pattern generation and are stored with the part.
- Bend allowance formula
- Bend allowance BA = (π/180) × A × (R + K × T), where A is bend angle in degrees, R is inside radius, K is K-factor, and T is thickness.
- K-factor definition
- The K-factor is the ratio locating the neutral axis within the material thickness. A common default is 0.44 for soft materials and is stored in the sheet metal style.
- Flat pattern creation
- A flat pattern is a derived representation created after the sheet metal feature. It appears as a separate browser node and is generated from the sheet metal style.
- Contour flange profile
- A contour flange requires an open profile along an edge and creates a flange of the sheet metal thickness following that profile shape.
- Punch tool behavior
- A punch tool is an iFeature or punch library item. It creates a hole and a corresponding feature in the flat pattern, preserving the punch shape.
- Corner seam treatment
- A corner seam closes the gap between two flanges. Corner Round and Corner Chamfer modify the seam edges to control the final corner shape.
- Make Components command
- Make Components converts solid bodies in a multi-body part into assembly components. The resulting components retain derived links to the original part.
