CSWP Engineering Drawings & Detailing Standards 3 — Questions and Answers
Question 1: What does the 'M' modifier symbol in a GD&T feature control frame signify when placed after a tolerance value?
- Maximum Material Condition (MMC) (Correct answer)
- Minimum Material Condition (LMC)
- Regardless of Feature Size (RFS)
- Projected Tolerance Zone
Correct answer: Maximum Material Condition (MMC)
The circled M modifier specifies Maximum Material Condition, meaning the tolerance applies when the feature contains the maximum amount of material.
Question 2: In SOLIDWORKS drawings, a 'Detail View' is typically used to:
- Show the entire part at a reduced scale
- Show a small portion of an existing view at an enlarged scale (Correct answer)
- Replace an auxiliary view
- Create a cross-section through a thin part
Correct answer: Show a small portion of an existing view at an enlarged scale
Detail Views show an enlarged portion of an existing view to clarify small or complex features that are difficult to dimension at the parent view scale.
Question 3: Which geometric tolerance controls the form of a flat surface regardless of any datum reference?
- Parallelism
- Flatness (Correct answer)
- Angularity
- Profile of a Surface
Correct answer: Flatness
Flatness is a form tolerance that controls how flat a surface is and requires no datum reference because it is self-referencing.
Question 4: When creating a drawing from a SOLIDWORKS assembly, which view type shows the assembly in its fully assembled state with no cross-section?
- Exploded view
- Standard 3 View (Correct answer)
- Section View
- Alternate Position View
Correct answer: Standard 3 View
Standard 3 View inserts front, top, and right-side views of the assembly in its assembled (non-exploded) state.
Question 5: In SOLIDWORKS, 'Ordinate Dimensions' are best used when:
- Tolerances need to stack from a common datum baseline to reduce accumulation error (Correct answer)
- Angular dimensions need to be shown from center
- Section views require multiple leaders
- Hole callouts are placed automatically
Correct answer: Tolerances need to stack from a common datum baseline to reduce accumulation error
Ordinate dimensions reference all measurements from a single origin (baseline), minimizing tolerance stack-up across multiple features.
Question 6: Which SOLIDWORKS drawing annotation automatically generates a table listing all holes in a drawing view with their sizes and quantities?
- Bill of Materials
- Hole Table (Correct answer)
- Revision Table
- General Table
Correct answer: Hole Table
A Hole Table in SOLIDWORKS automatically identifies all holes in a selected view and lists their X/Y coordinates, size, and count in a table.
Question 7: Per ASME Y14.5, what does a basic dimension (boxed dimension) indicate on a drawing?
- A theoretically exact dimension from which toleranced deviations are defined in a feature control frame (Correct answer)
- A reference dimension that does not control the part
- A dimension with tighter-than-standard tolerance
- A dimension that is not inspected
Correct answer: A theoretically exact dimension from which toleranced deviations are defined in a feature control frame
Basic dimensions are theoretically exact values enclosed in a box; actual tolerances for the feature are specified only in the associated GD&T feature control frame.
