Autodesk's ACP in Design for Manufacturing with Fusion is a 180-minute proctored exam delivered through Pearson VUE test centers and OnVUE online. It uses selected-response items answered without the software and is organized into six official objective domains, led by 3D component modeling. Autodesk recommends roughly 400 to 1,200 hours of Fusion experience and does not publish a fixed question count or passing score.

1When evaluating a part for subtractive manufacturing in Autodesk Fusion, a designer wants to verify that internal corners are large enough for a milling cutter to reach. Which design principle most directly drives the minimum acceptable internal fillet radius?
A.The internal corner radius must be at least equal to the cutting tool radius because a round cutter cannot produce a sharp internal corner
B.The radius must be smaller than the cutting tool radius so the tool can plunge
C.Internal corners should always be left perfectly square to maximize strength
D.The fillet radius is irrelevant to milling because only drilling is used in subtractive work
Explanation: A rotating end mill is cylindrical, so it can never cut a sharp internal corner; the smallest internal radius it can leave equals the tool radius. Designing internal fillets equal to or larger than the cutter radius ensures the corner is machinable without specialty tooling.
2In Fusion's Design workspace, which tool lets a designer assess whether a model's wall thicknesses and internal radii are accessible for a given cutting tool during subtractive machining evaluation?
A.The Sketch Dimension tool
B.The Section Analysis and minimum-radius evaluation tools in the Inspect menu
C.The Render environment selector
D.The Animation storyboard
Explanation: Fusion's Inspect menu contains analysis tools, including Section Analysis and curvature/minimum-radius checks, that let a designer evaluate tool access and machinability for subtractive manufacturing before producing toolpaths. These evaluation tools surface geometry that a cutter cannot reach.
3A part is being prepared for additive manufacturing using a fused-deposition-modeling (FDM) machine. Which design consideration is most important to address before exporting the model?
A.Adding the largest possible internal fillets to ease tool access
B.Removing all small features because additive machines cannot print details
C.Ensuring overhangs steeper than the machine's self-supporting angle have support structures or are reoriented
D.Maximizing wall thickness everywhere to guarantee a successful print
Explanation: In FDM and most additive processes, material is built layer by layer, so steep overhangs beyond the self-supporting angle will sag or fail without support material. Designers either add supports or reorient/redesign the part to keep overhangs within the printable angle.
4Which statement best describes the purpose of support material in additive manufacturing as covered in Fusion's design-for-manufacturing guidelines?
A.Support material increases the final mechanical strength of the printed part permanently
B.Support material is the same as the model's physical material assignment in the Inspect tools
C.Support material reduces print resolution to speed up the job
D.Support material temporarily holds up overhanging or bridging geometry during the build and is removed afterward
Explanation: Supports are temporary scaffolding that prevent overhangs and bridges from collapsing while each layer cures, and they are removed during post-processing. They are not part of the functional component, so designers try to minimize them through orientation and design choices.
5For a part that will be produced by injection molding, applying draft to the side walls is essential. What is the primary reason draft angles are required?
A.Draft allows the part to be ejected cleanly from the mold without scraping or sticking on the tool walls
B.Draft increases the part's wall thickness toward the parting line
C.Draft eliminates the need for a parting line entirely
D.Draft is only needed for sheet metal bends, not molded parts
Explanation: A small taper (draft) on faces parallel to the mold-opening direction lets the solidified part release from the cavity and core without galling or sticking. Without draft, friction between the part and steel can damage surfaces and make ejection difficult.
6Which Fusion tool helps a designer verify that all faces of a molded part have adequate draft relative to the pull direction?
A.The Joint command in the Assemble menu
B.The Draft Analysis tool in the Inspect menu
C.The Thicken command in the Surface tab
D.The Balloon command in the Drawing workspace
Explanation: Draft Analysis in the Inspect menu color-codes model faces based on their angle relative to a chosen pull direction, instantly highlighting faces with insufficient or negative draft. This lets the designer fix mold-release problems before tooling is created.
7A general design guideline for both injection molding and casting is to maintain uniform wall thickness. Why is uniform wall thickness preferred?
A.It guarantees the part will require no draft angle
B.It allows the part to be machined faster on a CNC mill
C.It promotes even cooling and reduces sink marks, warping, and internal voids
D.It removes the need for ribs and gussets in any design
Explanation: Thick and thin sections cool at different rates, causing differential shrinkage that produces sink marks, warpage, and voids. Keeping walls uniform helps the molten material cool evenly, improving dimensional stability and surface quality.
8In sheet metal design language, what does the term 'bend allowance' refer to?
A.The maximum number of bends a single flange can contain
B.The clearance gap left between two overlapping flanges
C.The angle at which a flange is automatically mirrored
D.The length of material along the neutral axis consumed in a bend, used to calculate the correct flat-pattern length
Explanation: Bend allowance is the arc length of the neutral axis through a bend, and it determines how much flat material is needed so the part folds to the correct finished dimensions. Fusion uses the sheet metal rule's K-factor to compute bend allowance for the flat pattern.
9Which of the following is a common sheet metal manufacturing tool referenced in design-for-manufacturing guidelines?
A.A press brake used to form bends in flat blanks
B.An injection-molding screw barrel
C.A FDM extrusion nozzle
D.A lost-wax casting crucible
Explanation: A press brake clamps flat sheet stock and forces it against a die to create precise bends, making it a primary sheet metal forming tool. Sheet metal design language anticipates press-brake constraints such as minimum flange length and bend radius.
10The K-factor in a Fusion sheet metal rule represents which physical quantity?
A.The total mass of the bent part
B.The ratio of the distance from the inner bend surface to the neutral axis divided by the material thickness
C.The number of flat patterns generated per design
D.The maximum bend angle the material can tolerate
Explanation: The K-factor is the ratio of the neutral-axis location (measured from the inside of the bend) to the material thickness, and it governs how much stretching occurs in a bend. A correct K-factor produces an accurate flat pattern and finished dimensions.
