Question 1

In SOLIDWORKS drawings, which GD&T application of Straightness (⏤) controls the derived axis of a cylindrical feature rather than its surface elements?

Accepted Answer

Straightness applied to the axis (centerline) of a cylinder

Answer

When Straightness is applied to the axis (derived center line) of a cylindrical feature, it specifies that the entire axis must lie within a cylindrical tolerance zone of the given diameter.

Question 2

What does a Maximum Material Condition (MMC) modifier — the circled M symbol — mean when applied to a GD&T tolerance in a SOLIDWORKS drawing?

Accepted Answer

The stated tolerance applies when the feature contains the most material, and bonus tolerance is earned as the feature departs from MMC

Answer

MMC means the specified tolerance applies at maximum material condition (smallest hole or largest pin), and additional 'bonus' tolerance becomes available as the actual feature departs from that extreme.

Question 3

In SOLIDWORKS, how do you correctly insert a Geometric Tolerance (GD&T) frame and attach it with a leader to specific drawing geometry?

Accepted Answer

Use Insert > Annotations > Geometric Tolerance and connect the leader to the target geometry

Answer

Geometric Tolerance symbols are created through Insert > Annotations > Geometric Tolerance, where you define the tolerance values and attach a leader to the specific edge or surface.

Question 4

What is the purpose of a 'Datum Feature Symbol' (filled triangle with a letter identifier) in a SOLIDWORKS GD&T annotation scheme?

Accepted Answer

To establish a physical reference feature from which geometric tolerances are measured

Answer

Datum Feature Symbols tag specific physical features on the part that serve as the datum reference framework — the stable, controlled surfaces from which all GD&T measurements originate.

Question 5

In SOLIDWORKS drawings, what does the Position (⊕) GD&T symbol specifically control?

Accepted Answer

The allowable variation in a feature's center location relative to datum-defined basic dimensions

Answer

True Position (⊕) defines a tolerance zone around the theoretically exact location (specified by basic dimensions from datums) within which the feature's center axis or plane must fall.
