- What is the End of Part marker?
- A draggable marker in the browser that rolls the part history back or forward, temporarily suppressing features below it so new features can be inserted mid-history.
- Fully constrained sketch color
- Sketch geometry turns black when fully constrained, meaning no degrees of freedom remain; blue indicates under-constrained geometry that can still move.
- Driven dimension
- A reference dimension shown in parentheses that reports a measured value but does not control geometry; it updates when the model changes.
- Insert constraint
- An assembly constraint that aligns two circular edges and mates their adjacent faces, commonly used for bolts, pins, and shaft-to-hole fits.
- Mate constraint
- An assembly constraint that makes two selected faces flush or mated, or aligns axes and points, removing translational and rotational degrees of freedom.
- Base view
- The first drawing view placed on a sheet; it establishes the orientation and scale from which projected, section, and detail views are derived.
- Projected view
- A drawing view created from an existing base or parent view, maintaining alignment and inheriting scale while showing an adjacent orthographic direction.
- Section view
- A drawing view cut by a sketched section line through the parent view, revealing internal geometry with hatching and an optional depth setting.
- Parts list
- A table placed on a drawing that lists components from the referenced assembly, driven by the bill of materials and iProperties such as part number.
- Balloon
- An annotation that attaches to a component in a drawing view and displays its item number, corresponding to the parts list entry.
- Symmetric constraint
- A sketch constraint that makes two entities mirror images about a selected line, or keeps two points equidistant from a line.
- Construction geometry
- Sketch lines and curves excluded from profiles but available as references for constraints, dimensions, symmetry, and revolve or sweep paths.
- Sketch Doctor
- A diagnostic tool that identifies open loops, overlapping geometry, and duplicate points preventing a sketch profile from forming a closed region.
- Through All termination
- An extrude or hole termination option that extends the feature through all remaining material in the specified direction, regardless of depth.
- Symmetric extrude
- An extrude option that applies the specified distance equally on both sides of the sketch plane, centering the resulting feature on the plane.
- Revolve feature
- A sketched feature that rotates a profile about an axis; the profile must not cross the axis, and the angle can be full or partial.
- Sweep feature
- A sketched feature that moves a profile along a path; the profile is typically sketched on a plane perpendicular to the path start.
- Loft feature
- A sketched feature that blends between two or more profiles on separate planes, with optional rails and centerlines to control the shape.
- Rib feature
- A thin extruded feature that adds stiffening material between two faces or along a sketch line, with options for thickness and draft.
- Shell feature
- A placed feature that hollows a solid by removing selected faces and leaving walls of a specified uniform thickness.
- Fillet feature
- A placed feature that rounds a selected edge with a constant or variable radius, blending adjacent faces to reduce stress concentration.
- Hole feature
- A placed feature that creates drilled, counterbored, countersunk, or tapped holes from sketched points, with termination and thread options.
- Work plane
- A reference plane created from faces, edges, or points, used to host sketches or as a termination or symmetry reference for features.
- iProperties
- Metadata fields on a file - Summary, Project, Status, and Custom - storing part number, description, and material that feed drawings and BOMs.
- Browser model tree
- The left panel listing features, sketches, and origin geometry in creation order, used to edit, suppress, reorder, or roll back the model.
- Quick Access Toolbar
- A customizable row of frequently used commands above the ribbon, populated by right-clicking a ribbon command and choosing Add to Quick Access Toolbar.
- Project file (.ipj)
- A file defining search paths for libraries, workgroups, and Content Center, controlling how referenced files are resolved in an assembly.
- Application Options
- Global settings under the Tools tab that control behavior across all files, such as undo count, auto-save interval, and sketch inference.
- ViewCube
- A navigation widget in the corner of the graphics window used to rotate to standard views, set home view, and toggle orthographic or perspective projection.
- Assembly degrees of freedom
- The remaining translational and rotational movement of a component not yet constrained; the status bar reports them, and zero means fully constrained.
- Grounded component
- An assembly component with all degrees of freedom removed; the first placed component is grounded by default and can be toggled via the Grounded command.
- Bill of materials structure
- The assembly setting (normal, inseparable, or purchased) that determines how components roll up into the parts list and drawing BOM.
