CSWP Drawing Views and Annotations Flashcards

In a SolidWorks drawing, which dimension type measures the true length along a curved arc entity?

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.

The Ordinate dimensioning scheme in SolidWorks drawings measures all dimensions relative to what?

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.

Which tolerance type displays the allowable variation as two stacked numerical limits (maximum above, minimum below)?

Answer: Limit

The Limit tolerance type shows the maximum and minimum acceptable values stacked as two separate numbers, making the acceptable range immediately clear.

In GD&T, the Flatness tolerance controls what characteristic of a surface?

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.

Which GD&T symbol specifies that a cylindrical surface must fall within a cylindrical tolerance zone that is coaxial with its true axis?

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.

A True Position GD&T callout controls what aspect of a feature?

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.
