- Autodesk reports ACA results as pass/fail only - there is no published numeric cut score to target.
- Domain 1 (3D component modeling and project files) carries 61% of the exam, making it the priority for study time.
- The exam has 45-60 questions in 120 minutes, so pacing matters as much as accuracy.
- Standard retail exam fee is listed at US$200 on the credential page; confirm the price at checkout since Autodesk's general table shows US$150.
Is There an Official ACA Passing Score?
If you're searching for a specific number - "70%," "75%," "you need 42 out of 60" - for the Autodesk Certified Associate in CAD for Mechanical Design exam, that number doesn't exist publicly. Autodesk does not publish a scaled passing score or a percentage threshold for this credential. What Autodesk does confirm is the format: 45-60 questions, a 120-minute time limit, and a result that comes back as pass or fail, not a numeric score report.
That absence of a published cut score isn't a gap in this article - it's a fact about how the exam is scored, and it changes how you should prepare. Instead of chasing a target percentage, your goal is to build broad, reliable competence across all three exam domains, because Autodesk's grading treats the exam as a whole rather than handing you a breakdown of where you lost points.
Why Results Show Pass/Fail, Not a Number
Autodesk's own certification support documentation confirms that results for this exam are reported as pass/fail. You won't get a percentage breakdown by domain after the exam, and you won't see how close you were to passing. This is a deliberate design choice common to skills-based associate credentials - the certifying body cares whether you can perform the tasks, not whether you scored 68% versus 82%.
For candidates, this has a practical implication: there's no partial credit story to obsess over. You either demonstrate sufficient competence across component modeling, assembly work, and drawing creation, or you don't. That reframes exam prep away from "how many points do I need" and toward "which domain am I weakest in, and does that weakness show up often enough in a 45-60 question exam to sink me."

Key Takeaway
Stop trying to reverse-engineer a passing percentage. Instead, use the domain weights below to decide where a wrong answer is most likely to occur, and shore up that area first.
What the Domain Weights Tell You About Effort
The October 2024 exam objectives define three weighted domains. Since the pass/fail outcome depends on your overall performance across the full question set, and questions are drawn from these domains in roughly the proportions below, the weighting is your best proxy for where study time should go.
| Domain | Weight | Study Priority |
|---|---|---|
| 3D component modeling and project files | 61% | Highest - majority of all questions |
| 3D assembly modeling and management | 24% | Second priority |
| Technical detailed drawing creation | 15% | Smallest share, but not skippable |
Domain 1: 3D Component Modeling and Project Files (61%)
This domain dominates the exam. Because it accounts for well over half of all questions, weakness here is the single most likely reason a candidate fails, even if their assembly and drawing skills are solid.
- Sketch-based and direct modeling workflows in Fusion
- Feature creation, editing, and modification order
- Managing project files, data organization, and file relationships
Domain 2: 3D Assembly Modeling and Management (24%)
Roughly a quarter of the exam covers how components come together, move, and behave as assemblies.
- Joint types, constraints, and assembly structure
- Component relationships and how edits propagate through an assembly
- Assembly organization and management within a project
Domain 3: Technical Detailed Drawing Creation (15%)
The smallest domain by weight, but still enough questions that skipping it outright is risky given there's no partial-credit safety net on a pass/fail result.
- Drawing view creation from 3D models
- Dimensioning and annotation conventions
- Drawing sheet setup and layout management

Question Formats That Decide Whether You Clear the Bar
Because there's no numeric score to aim for, format familiarity becomes one of the biggest controllable factors in whether you pass. The exam uses several selected-response formats rather than free-form CAD tasks:
- Multiple choice - standard single or multi-select questions
- Drag-and-drop - sequencing or matching steps and elements
- Active-screen - interacting with a simulated interface element
- Hot-area - selecting a specific region of an image or interface
- Graphic interpretation - reading a model, drawing, or diagram to answer a question
One detail trips up unprepared candidates: Fusion software itself is not available during the exam. You are being tested on your knowledge of Fusion workflows, terminology, and outcomes - not given a live modeling environment to click through. That means memorizing exact menu paths matters less than being able to look at a screenshot of a feature tree, a sketch, or an assembly constraint and correctly interpret what's happening or what should happen next.
Exam Logistics That Affect Your Score
A few operational details influence how you perform on exam day, even though they aren't "content":
- Length and pacing: 45-60 questions in 120 minutes gives you roughly two to two-and-a-half minutes per question on average, but graphic interpretation and drag-and-drop items often take longer than straight multiple choice. Budget accordingly.
- Delivery channel: You can sit the exam at a Pearson VUE testing center or through OnVUE online proctoring, both requiring identity verification and an Autodesk Account registered in advance.
- Language: The exam and proctor support are available in English.
- Fee: The credential-specific listing states a US$200 standard retail exam fee. Autodesk's general Associate fee table separately lists US$150, so confirm the actual price shown at checkout in your Autodesk Account before paying. See ACA Certification Cost 2026: Complete Pricing Breakdown for a full cost breakdown.
None of these logistics change what's tested, but a candidate who shows up unsure whether they registered correctly, or who misjudges pacing across 45-60 questions, effectively lowers their own performance regardless of how well they know Fusion.

Building a Study Plan Around Domain Weight
Generic study techniques - spaced repetition, timed drills, active recall - only help if you're applying them to the right material in the right proportion. Since Domain 1 alone accounts for 61% of the exam, a study plan that spends equal time on all three domains is mathematically misallocated. Here's a domain-weighted structure over four weeks:
Domain 1 - Component Modeling and Project Files
- Drill sketch and direct modeling workflows until feature order becomes second nature
- Practice reading feature-tree screenshots without opening Fusion
- Review project file organization and data management rules
Domain 2 - Assembly Modeling and Management
- Work through joint types and constraint behavior
- Trace how a single component edit propagates through an assembly
- Practice assembly-structure graphic interpretation questions
Domain 3 + Full Review
- Cover drawing view creation, dimensioning, and sheet setup
- Run full-length timed practice sessions to test 120-minute pacing
- Revisit weak spots flagged during earlier weeks
This isn't a generic template swapped in from another certification - it's built directly around the 61/24/15 split so your heaviest study investment matches the heaviest-weighted content. For a more detailed week-by-week plan with resource recommendations, see ACA Study Guide 2026: How to Pass on Your First Attempt. You can also run full-length timed drills on our practice test platform to get a feel for pacing before exam day.
Key Takeaway
Spend roughly six-tenths of your prep time on Domain 1, a quarter on Domain 2, and the remainder on Domain 3 - matching the exam's own weighting rather than splitting time evenly.
What Happens If You Don't Pass
Because there's no score report showing "you were close," a failed attempt gives you limited diagnostic feedback beyond a pass/fail result. What Autodesk does specify clearly is the retake timeline:
- After a first failed attempt, you may reschedule immediately, subject to seat availability at your chosen testing center or OnVUE slot.
- After a second or subsequent failed attempt, you must wait 72 hours before retesting.
Since you won't get a domain-by-domain score breakdown to diagnose what went wrong, use the waiting period productively: re-run practice questions weighted toward Domain 1 first (since it's statistically the most likely source of missed questions), then Domain 2, then Domain 3. If you're weighing whether to invest in a retake versus stopping altogether, Is the ACA Certification Worth It? Complete ROI Analysis 2026 looks at the credential from a broader cost-benefit angle.
It's also worth remembering that certification is valid for three years, and renewal requires submitting a new application during the final six months before expiration and passing the exam again before it lapses - there is no grace period. Passing cleanly the first time avoids that clock pressure later.

FAQ
Autodesk does not publish a numeric passing score or percentage for the Autodesk Certified Associate in CAD for Mechanical Design exam. Results are reported strictly as pass/fail, so there's no public cut score to target.
No. The result comes back as pass or fail without a domain-by-domain breakdown or percentage, so you can't tell exactly how close you were on a failed attempt.
Domain 1, 3D component modeling and project files, carries 61% of the exam - by far the largest share - so it deserves the largest share of your study time, followed by Domain 2 (24%) and Domain 3 (15%).
No. Fusion is not available during the exam. Questions use formats like multiple choice, drag-and-drop, active-screen, hot-area, and graphic interpretation instead of live software access.
After your first failed attempt, you may reschedule immediately if a testing slot is available. After a second or later failed attempt, Autodesk requires a 72-hour wait before you can retest.
