Autodesk Fusion ACU flashcards
Autodesk Fusion ACU · Build recall with a focused review session.
32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Application Bar
- The top strip of the Fusion window containing the Data Panel toggle, File menu, Save, Undo/Redo, and the workspace switcher used to move between Design, Manufacture, and other workspaces.
- Browser
- The left-hand panel that lists the model structure as a feature tree, including bodies, sketches, components, origins, joints, and construction geometry, each with visibility and suppression controls.
- Component vs. body
- A component is a container with its own origin and coordinate system that can hold bodies and subcomponents; a body is raw geometry inside a component and cannot be jointed directly.
- Fully constrained sketch
- A sketch state in which all degrees of freedom are removed by dimensions and constraints, indicated by a color change and a status message, so geometry cannot move unexpectedly.
- Driving dimension
- A sketch dimension that controls the size of geometry; changing its value resizes the entity, unlike a driven dimension shown in parentheses that only reports size.
- Construction geometry
- Dashed sketch lines and curves used as references or guides that are excluded from profile selection, so they do not create solid features when extruded.
- Closed profile
- A fully bounded region of sketch geometry required for solid Extrude and Revolve operations; open profiles can only drive thin features or surfaces.
- Project geometry
- A sketch command that brings model edges or faces into the sketch as reference or construction lines, linking sketch entities to existing model topology.
- Extrude operations
- The operation types available in Extrude: Join adds material, Cut removes it, Intersect keeps only overlap, and New Body or New Component creates separate geometry.
- Revolute joint
- An assembly joint that removes five of six degrees of freedom, allowing rotation about a single axis between two components, with optional minimum and maximum limits.
- As-built joint
- A joint that captures the current relative position of two components without moving them, useful for imported assemblies already positioned correctly.
- Shell feature
- A modify feature that removes selected faces and hollows a solid to a specified wall thickness, often applied after draft so walls follow drafted faces.
- Drawing view associativity
- The property that drawing views are linked to the model, so editing the model updates base, projected, section, and detail views when the drawing rebuilds.
- Appearance vs. material
- An appearance controls visual properties such as color and texture, while a physical material supplies density and strength used for mass properties and simulation.
- Section analysis
- A temporary display tool that cuts a view to reveal internal geometry without creating a feature or modifying the model, unlike a drawing section view.
- STL export
- A mesh export format for 3D printing that tessellates the model into triangles; resolution settings control triangle density and resulting file size.
- Rigid joint
- An assembly joint that locks all six degrees of freedom between two components, preventing any relative motion and effectively fixing their relative position.
- Slider joint
- An assembly joint that permits translation along a single axis while removing the other five degrees of freedom, with optional motion limits.
- User parameter
- A named value created in the parameter table that can be referenced in dimensions and feature inputs, allowing one change to update many dependent features.
- Timeline
- The horizontal feature history at the bottom of the canvas that records features in creation order and allows editing, suppressing, reordering, or rolling back the model state.
- Base feature
- A feature created before the parametric timeline, typically from imported geometry, that lacks the history and parametric behavior of normal features.
- Marking menu
- A context menu opened by holding the right mouse button that offers commands relevant to the current selection, with gesture support configurable in Preferences.
- ViewCube
- An on-screen navigation control that aligns the camera to standard views such as front, top, and right, and supports orbiting by dragging its faces and corners.
- Interference check
- An assembly analysis that detects overlapping bodies and reports the volume of overlap, helping identify fit problems before manufacturing.
- Grounded component
- A component fixed in space so it cannot move; typically the first component placed in an assembly, providing a stable reference for joints.
- Contact set
- An assembly setting that prevents selected bodies from interpenetrating without defining a joint; it approximates collision and adds computational cost.
- STEP format
- A neutral solid interchange format (AP203/AP214) widely used to move precise geometry between CAD systems while preserving solid topology.
- DXF export
- A 2D vector export of sketch or drawing geometry used for laser cutting and CNC, where layers and units must be set correctly before export.
- Detail view
- A drawing view that magnifies a region of a parent view, bounded by a circle or rectangle and labeled to show the enlarged area.
- Auxiliary view
- A drawing view projected perpendicular to an inclined face or edge so the true shape of that feature appears without foreshortening.
- Driven dimension
- A sketch or drawing dimension shown in parentheses that reports the measured size but does not control geometry; it cannot drive changes.
- Over-constrained sketch
- A sketch state where redundant or conflicting dimensions and constraints exist, producing a warning that must be resolved by removing the conflict.
