ACA Cheat Sheet 2026: One-Page Review of Must-Know Facts

TL;DR
  • ACA is Autodesk's Fusion-based mechanical design credential - not AutoCAD, and no software is available during the test.
  • Domain 1 (3D component modeling and project files) carries 61% of the exam, more than the other two domains combined.
  • The exam runs 45-60 questions in 120 minutes, delivered at Pearson VUE centers or via OnVUE online proctoring.
  • Retail listing price is US$200; confirm your checkout total since Autodesk's general Associate fee table shows US$150.

The Three Domains at a Glance

The October 2024 objectives split the exam into three weighted domains. Weight isn't just trivia - it should directly shape how many practice hours you spend on each area. A candidate who studies all three domains equally is under-preparing for the domain that actually decides the result.

Domain 1: 3D Component Modeling and Project Files - 61%

This is the exam. Nearly two-thirds of your questions live here, so mastery of Fusion's part-modeling workflow is non-negotiable.

  • Sketch constraints, dimensions, and profile creation
  • Feature-based modeling: extrude, revolve, sweep, loft, and modifying features after creation
  • Managing project files, data panel organization, and file structure within Fusion
  • Parametric design intent - editing a feature and understanding downstream effects

Domain 2: 3D Assembly Modeling and Management - 24%

The second-largest slice covers how individual components come together and behave as a system.

  • Joint types and mate/motion relationships between components
  • Assembly structure, component visibility, and organization
  • Managing constraints and detecting interference or motion conflicts

Domain 3: Technical Detailed Drawing Creation - 15%

The smallest domain by weight, but still enough questions to matter if you skip it.

  • Generating drawing views from 3D models
  • Adding dimensions, annotations, and basic drawing standards
  • Translating a modeled assembly into a documented, readable drawing sheet

Want the item-level breakdown of what each domain actually tests, topic by topic? That's covered in the ACA Exam Domains 2026 Complete Guide.

Exam Format & Question Types

Because Fusion itself is unavailable during the test, every question is a selected-response format built to simulate hands-on decision-making without live software access. Expect a mix of:

  • Multiple choice - standard single or multi-answer questions
  • Drag-and-drop - sequencing steps or matching terms to workflows
  • Active-screen - interacting with a simulated interface element
  • Hot-area - clicking the correct region of an image or screenshot
  • Graphic interpretation - reading a model, sketch, or drawing view and answering based on what's shown

This format mix means recognizing an icon or reading a rendered feature tree matters just as much as remembering terminology. If you've never seen this exam interface before, spend time understanding what "hard" actually means for this specific format mix in How Hard Is the ACA Exam? Complete Difficulty Guide 2026.

Key Takeaway

Because there's no live Fusion access during the test, practice reading feature trees and drawing views from static images, not just performing the operations yourself in the software.

Registration, Fees & Scheduling

Registration runs through your Autodesk Account, with identity verification required whether you sit the exam at a Pearson VUE test center or take it remotely through OnVUE online proctoring. A few mechanics worth locking in:

  • The credential-specific listing quotes 45-60 questions and 120 minutes - use this for time-budgeting, roughly two minutes or less per question with buffer for review.
  • Standard retail price is listed at US$200; because Autodesk's general fee table elsewhere shows US$150, always confirm the actual charge at checkout before assuming either number.
  • The exam and proctoring are offered in English only.
  • Results report as a straightforward pass or fail - there's no scaled score breakdown by domain shown to the candidate.

For candidates weighing whether prior classroom hours or specific software versions are required to sit the test, the eligibility rules are laid out fully in ACA Requirements 2026: Eligibility, Prerequisites & How to Qualify. And if you're still deciding when to book your seat, the scheduling windows and deadlines live in ACA Exam Dates 2026.

No Formal Prerequisite: Approximately 150 hours of relevant Fusion experience is preparation guidance, not a mandatory course or prerequisite you must document before registering. Anyone with an Autodesk Account can book the exam.

Retake Policy & Renewal Rules

Two policy details show up constantly in candidate questions, so memorize them exactly:

  • First failed attempt: rescheduling may be immediate, subject to seat availability at your chosen Pearson VUE center or OnVUE slot.
  • Second and later failed attempts: you must wait 72 hours before your next retake.
  • Certification validity: three years from the pass date.
  • Renewal: submit a new application during the final six months before expiration, then purchase and pass the exam again before the expiration date - there is no grace period.

Missing that renewal window means starting over rather than simply extending your credential, so treat the six-month renewal application period as a hard deadline on your calendar. The exact scoring threshold that determines pass vs. fail is explained in ACA Passing Score 2026: Exactly What You Need to Pass, and if you're curious how many candidates clear that bar on the first try, see ACA Pass Rate 2026: What the Data Shows.

Who This Credential Signals To

Because the exam tests Fusion specifically rather than general drafting theory, it's most relevant to employers running Fusion-based workflows for product design, manufacturing prep, and mechanical component development. Entry-level and student candidates use it to demonstrate concrete Fusion competency - sketching, feature modeling, assemblies, and drawing output - rather than vague CAD familiarity.

Final-Week Review Timeline

If your exam date is close and you need a compressed schedule tied directly to domain weight rather than a generic study calendar, allocate your remaining days proportionally - Domain 1 gets the most repetition because it's worth the most.

Days 1-3

Domain 1 deep review (61% weight)

  • Rebuild 5-6 parts from scratch using sketches, extrude/revolve/sweep/loft features
  • Practice editing a feature and predicting the downstream model change
  • Review project/data panel organization inside Fusion
Days 4-5

Domain 2 review (24% weight)

  • Build a small multi-component assembly and apply joints/motion
  • Practice spotting interference or constraint conflicts
Day 6

Domain 3 review (15% weight)

  • Generate drawing views from a completed model and add annotations
  • Practice reading a finished drawing sheet cold, without building it yourself
Day 7

Full simulation

For a more detailed week-by-week plan that isn't compressed into seven days, the full ACA Study Guide 2026 walks through a longer runway.

Pre-Exam Mental Checklist

Run through this list the night before, not the morning of:

  • Confirm your testing method - Pearson VUE center location or OnVUE system check completed in advance.
  • Confirm your Autodesk Account login and identity documents match what's required for verification.
  • Recheck the checkout price you were actually charged against the US$200 listing so there are no surprises.
  • Mentally rehearse Fusion menus and icons since you won't have the software open during the test - active-screen and hot-area questions rely on visual recall.
  • Remind yourself of the retake rule: a first fail may let you rebook immediately, but plan for at least a 72-hour gap if it happens again.

Running a handful of full-length simulations on our ACA practice tests before test day is the single fastest way to convert domain knowledge into exam-day speed, since the graphic-interpretation and hot-area formats reward familiarity with the question style, not just the underlying Fusion skill.

Frequently Asked Questions

Does the ACA exam test AutoCAD or Fusion?

This mechanical design credential tests Autodesk Fusion, not AutoCAD, despite the shared "CAD" naming in the credential title.

Can I use Fusion during the actual exam?

No. Fusion software is unavailable during the exam; all questions are selected-response formats (multiple choice, drag-and-drop, active-screen, hot-area, graphic interpretation) rather than live modeling tasks.

How many questions and how much time do I get?

The credential-specific listing gives 45-60 questions within a 120-minute time limit, delivered at a Pearson VUE test center or through OnVUE online proctoring.

What happens if I fail?

After a first failed attempt, you may be able to reschedule immediately depending on seat availability. After a second or later failed attempt, you must wait 72 hours before retesting.

How long does the certification stay valid, and how do I renew it?

It's valid for three years. Renewal requires submitting a new application during the final six months of that period, then purchasing and passing the exam again before it expires - there is no grace period.
