AFAB 110 MIDTERM STUDY GUIDE UNITS 1- 8 QUESTIONS AND ANSWERS (SCORED) A+.

Are you taking AFAB 110 (Print Reading/Drafting) and preparing for the midterm exam? This comprehensive study guide covers Units 1 through 8 with questions and answers scored A+ by successful students. From spatial instruments and section views (removed, revolved, broken-out, offset, aligned) to the alphabet of lines, dimensioning, title blocks, and drafting conventions – this resource is your all-in-one exam preparation tool. What's Inside – Complete AFAB 110 Midterm Domain Coverage: Category Key Concepts & Questions Covered Drafting Fundamentals Definition of drafting (creating technical drawings), vellum (original drawings before copiers), alphabet of lines (standardized list of line types), conventions (generally accepted ways of doing things) Spatial Instruments What is NOT a spatial instrument (playing 3D tic-tac-toe) Dimension Terms Three dimension terms common to drafting education (identifying which is NOT correct) Section Views (Critical Topic) Removed section (section view located out of projection with other views), Revolved section (can be overlaid or separated with short break lines), Broken-out section (requires short break line), Offset section (section view no longer aligned in projection), Aligned section (best for cylindrical objects with odd number of features – spokes/holes on bolt circle), Outline section (section lines only around perimeter for large areas) Conventional Practices in Sectioning Features left unhatched when cutting-plane line passes through (hole is NOT relevant – relevant: ribs, webs, spokes); Parts filled solid in assembly drawings (springs is NOT relevant – relevant: shafts, bolts, keys, ball bearings) Alphabet of Lines Visible line (most important line – also called object line), Hidden line (pattern of dashes of same length), Cutting-plane line (drawn THICK, arrowheads on each end), Phantom line (long dash alternating with two short dashes), Center line (shows path of motion), Extension line (perpendicular to dimension line), Short break line (used with broken-out sections), Chain line (NOT for paths of motion – false), Dotted line (fictitious – not a real standard line) Line Weights & Standards Each line type has ONE option for appearance? FALSE; Recent standards recommend only TWO line weights: thick and thin? TRUE; Hidden lines sometimes omitted on complex views if drawing is clear? TRUE; Latest standards set exact thickness and dash/space lengths? FALSE; Paths of motion indicated with chain line? FALSE Dimensioning Leader (points to feature with local note – TRUE); Extension lines (sometimes called witness lines in textbooks/CAD – TRUE, but term not in standards); Break line is NOT a type of dimensioning line Text & Notes on Prints Text/numeric information referred to as printing? FALSE; Text most commonly in lowercase letters? FALSE (uppercase standard); Single-stroke gothic (hand-drawn letters with one continuous stroke? FALSE) Title Block Information Revision history block (determines if print is up-to-date), Finish (area requiring signature/initials is LEAST expected), Least likely part of standard title block: fine number (vs revision block, title block, tolerance block) Sheet Sizes D-size sheet properly cut yields how many A-size sheets? 8 (D = 22"x34", A = 8.5"x11" – area ratio ~8:1) Geometric Terms Section (means cut in half); Hexagon inscribed in circle – diameter = across the corners; Primitives (basic geometric forms in CAD systems used to create complex models) True/False Questions Comprehensive coverage of line standards, conventions, dimensioning practices, and drafting terminology Key Questions & Answers You'll Master: Question Correct Answer Which is NOT an example of a spatial instrument? Playing 3D tic-tac-toe Type of section view no longer aligned in projection with other views? Offset section Cylindrical object with odd number of features (spokes/holes on bolt circle) – best section type? Aligned section Broken-out section requires what type of line for jagged break? Short break line Section type that can be overlaid or separated with short break lines? Revolved section Section type located out of projection with other views? Removed section Large area needing section lines only around perimeter – which section? Outline section What is NOT relevant to the practice of leaving features unhatched? Hole (ribs/webs/spokes ARE relevant) What is NOT relevant to parts filled solid in assembly drawings? Springs (shafts/bolts/keys/bearings ARE relevant) Each type of line has one and only one option for appearance? FALSE Recent standards recommend how many line weights? Two: thick and thin Hidden lines can be omitted on complex views if drawing is clear? TRUE Paths of motion indicated with chain line? FALSE What is the most important line in an industrial print (also called object line)? Visible line Which line has a pattern of dashes of the same length? Hidden line Cutting-plane lines have what on each end? Arrowhead Which line is fictitious (not a real standard line)? Dotted line Long dash alternating with two short dashes describes which line? Phantom line May show a path of motion – which line? Center line Perpendicular to a dimension line – which line? Extension line How many A-size sheets from one D-size sheet? 8 Block that determines if print is up-to-date? Revision history What does "section" basically mean? Cut in half Hexagon inscribed in circle – diameter equals? Across the corners Basic geometric forms in CAD to create complex models? Primitives Why This Guide Works: Scored A+ – Verified answers for AFAB 110 midterm Units 1-8 complete – Full semester coverage Exam-style Q&A – Mirrors actual test format Section view mastery – Removed, revolved, broken-out, offset, aligned, outline Alphabet of lines – Complete line type identification with T/F questions Perfect for: AFAB 110 Print Reading students Drafting and design technology majors Engineering technology students Manufacturing and industrial trades programs Anyone learning technical drawing interpretation
