CSWP CSWP Drawing Views and Annotations 2 — Questions and Answers
Question 1: In a SolidWorks drawing, which dimension type measures the true length along a curved arc entity?
- Radial Dimension
- Angular Dimension
- Arc Length Dimension (Correct answer)
- Ordinate Dimension
Correct answer: Arc Length Dimension
Arc Length Dimension places a dimension showing the actual distance along the arc path, distinguished from the chord length or the radius.
Question 2: The Ordinate dimensioning scheme in SolidWorks drawings measures all dimensions relative to what?
- The geometric center of the part
- A common baseline or datum origin (Correct answer)
- Each previous feature's position
- The title block reference corner
Correct answer: A common baseline or datum origin
Ordinate dimensioning chains all dimensions back to a single zero-origin datum, eliminating accumulated tolerance errors common with chained dimensions.
Question 3: Which tolerance type displays the allowable variation as two stacked numerical limits (maximum above, minimum below)?
- Symmetric
- Bilateral
- Limit (Correct answer)
- Basic
Correct answer: Limit
The Limit tolerance type shows the maximum and minimum acceptable values stacked as two separate numbers, making the acceptable range immediately clear.
Question 4: In GD&T, the Flatness tolerance controls what characteristic of a surface?
- Its location relative to a datum plane
- Its orientation relative to another surface
- How flat the surface is regardless of its position or orientation (Correct answer)
- The parallelism between two opposing surfaces
Correct answer: How flat the surface is regardless of its position or orientation
Flatness is a form control that constrains all points of a surface to lie within two parallel planes separated by the tolerance value, with no datum reference required.
Question 5: Which GD&T symbol specifies that a cylindrical surface must fall within a cylindrical tolerance zone that is coaxial with its true axis?
- Flatness
- Straightness
- Cylindricity (Correct answer)
- Circularity
Correct answer: Cylindricity
Cylindricity is a composite form control requiring that all surface elements of a cylinder simultaneously satisfy roundness, straightness, and taper, all within a single cylindrical zone.
Question 6: A True Position GD&T callout controls what aspect of a feature?
- The physical size of the feature
- The exact location of a feature relative to specified datum references (Correct answer)
- The surface roughness of the feature
- The angular orientation of the feature only
Correct answer: The exact location of a feature relative to specified datum references
True Position defines a tolerance zone (typically cylindrical) centered on the theoretically exact location of a feature relative to datums, controlling where the feature actually exists.
