ASME GDTP Technologist study plan

Define each of the 14 geometric characteristic symbols and state which tolerance category each belongs to, without notes

Apply Rule #1 (envelope) and Rule #2 (RFS default) to at least 15 short feature descriptions and predict the resulting boundary

Identify the six degrees of freedom and list which ones each of the three datum planes constrains

Sequence datum features by precedence (primary, secondary, tertiary) and justify each choice for 10 described parts

Distinguish datum features from datums and distinguish datum targets from datum feature simulators

Compute bonus tolerance at MMC and at LMC for at least 20 described hole and pin conditions

Translate a stated position tolerance at MMC into the virtual condition and the allowable gage size for each case

Construct the datum reference frame for patterns of features and explain how a pattern-locating control differs from a feature-relating control

Explain why concentricity and symmetry are difficult to verify and state when position or profile is preferred instead

Calculate the total allowable positional deviation for a feature at its actual size, including any datum feature shift

Derive virtual condition, inner boundary, and outer boundary for internal and external features at MMC, LMC, and RFS

Construct a composite position tolerance (position of a pattern plus feature-relating position) and state what each segment controls

Distinguish the effect of MMB, LMB, and RMB modifiers on datum features and predict the resulting shift allowance

Interpret a described drawing callout combining size, position, and a datum pattern and list the inspection sequence an inspector would follow

Compute the worst-case functional gage size for a described multi-feature pattern

Distinguish profile of a line from profile of a surface and state the default and stated tolerance zone shapes

Apply the all-around and all-over symbols and describe the resulting zone for 10 described part geometries

Explain how profile can control size, form, orientation, and location simultaneously and when a bilateral or unilateral zone applies

Compare composite profile with a two-segment profile callout and state the difference in datum referencing

Determine when profile of a surface may be used without datum references and what that implies about the tolerance zone orientation

Differentiate flatness, straightness, circularity, and cylindricity by the zone shape each produces and the number of datum references each permits

Apply straightness of a surface and straightness of an axis (with and without size modifier) and state the resulting boundary effect

Determine when orientation tolerances (parallelism, perpendicularity, angularity) imply a form control on a feature of size

Compute the implied form tolerance for a feature of size governed by Rule #1 at its stated limits

Select the correct form or orientation control for 15 described inspection problems

Distinguish circular runout from total runout by zone shape, feature coverage, and what each does and does not control

Explain why runout always requires a datum axis and how the datum axis is established from a cylindrical datum feature

Identify what runout does not control (e.g., size, cylindricity) and select a different control when those are needed

Combine runout with orientation or form controls in described applications and justify the combination

Interpret runout applied to a face relative to a datum axis and describe the resulting tolerance zone

Read a fully described multi-control drawing scenario and sequence the verification steps for each control in the correct order

Identify conflicting, redundant, or non-conforming callouts in 12 described drawing situations and state the correction

Resolve composite and combined control calls by separating pattern-locating from feature-relating requirements

Re-derive from memory the full symbol set, modifier set, and default rules without reference

Revisit and re-solve every item missed in weeks 1 through 6

Complete two full-length timed mock exams under test conditions and score each

Analyze every missed mock-exam item to its root concept and re-study that concept to demonstrated mastery

Recite the definitions of virtual condition, bonus tolerance, datum shift, and composite tolerance without notes

Practice explaining out loud the reasoning behind 20 mixed-domain items as if teaching them

Consolidate all reference sheets into a single final review document
