ExploreAbout this exam
Craftsman Computer Aided Mechanical Drawing is a trade-level certification for people who produce mechanical drawings with CAD software - drafters, machinist-technicians, tooling staff, and engineering students who want documented proof that they can turn a part into a clean, standards-compliant drawing set. The exam blends multiple-choice items with drawing and interpretation tasks, so it tests both vocabulary and hands-on output: line conventions and projection rules on one side, layer setup and plotting on the other. Content spans engineering drawing fundamentals, CAD operation and file management, 2D geometric construction, orthographic multi-view work, dimensioning, tolerancing and fits, sections and auxiliary views, mechanical part and assembly drawings, and output documentation. Expect to read a drawing as often as you produce one - spotting a missing dimension, an incorrect section hatch, or a tolerance that cannot be inspected is exactly the skill being measured. Preparation works best as a loop: work through a drafting standards reference, then redraw a real bracket, shaft, or housing in CAD from scratch, including title block, scale, and plot output. Practice under time pressure with printed or PDF drawings since hand-sketching and annotation speed matter. Confirm current test dates, fees, and delivery method with the issuing body, as these details change.
What you'll study
About Craftsman Computer Aided Mechanical Drawing preparation
What is the exam format?
It combines multiple-choice questions with drawing and interpretation items, so you should be comfortable both answering theory and producing or reading an actual drawing. The issuing body publishes the current structure, item count, and delivery method; check its official site before you register rather than relying on older forum posts.
How difficult is it?
Candidates with real drafting practice usually find the projection and section items manageable, while tolerancing and fits trip up those who only know CAD commands. The exam rewards people who understand why a drawing is dimensioned a certain way, not just how to draw lines quickly.
Can I retake it if I fail?
Retake rules, waiting periods, and any repeat fees are set by the issuing organization and vary over time. Look up the current retake policy on its official website, and ask whether a partial result or score report is issued so you know which domains to target before rebooking.
How much time do I get, and how long should I study?
The official body publishes the current time limit and any section timing. As a study guide, plan several weeks of regular practice: drafting standards reading plus repeated full drawing exercises with title block, dimensions, and a plotted output. Speed comes from repetition on familiar part types, not from last-minute memorization.
In what order should I study the topics?
Start with drawing fundamentals and projection, since every later topic depends on them. Then move to 2D construction and CAD environment setup, followed by dimensioning, tolerancing, and fits. Finish with sections, auxiliary views, assembly drawings, and plotting, and do at least one complete drawing set end to end.
What are the most common failure modes?
Missing or duplicated dimensions, incorrect view alignment, wrong section hatching direction, tolerance values that do not match the stated fit, and drawings that plot with unreadable line weights or missing title block data. Candidates also lose time redrawing instead of using blocks, layers, and templates.
Do I need to know a specific CAD package?
The concepts - layers, line types, model versus paper space, scale, and plotting - transfer across packages, so focus on principles rather than one vendor's menus. Confirm with the issuing body whether a particular software environment is used for the practical items before you commit your practice time.
Is this an official certification page?
No. This is independent study material for candidates preparing for the exam. It is not affiliated with or endorsed by the issuing organization, and all administrative details such as fees, dates, and passing scores should be verified on the official body's website.
