Geometric Tolerance

The GeometricTolerance command creates a geometric-tolerance feature control frame as an annotation text object in the model. It opens a dialog where you can define the GD&T parameters, including geometric symbols, tolerance values, material conditions, etc. Geometric tolerances are crucial for ensuring that parts are manufactured within acceptable limits and can be assembled correctly.

Steps

  1. Run the GeometricTolerance command.

  2. Fill out the fields in the editor as needed, then click OK.

  3. Pick a location in the viewport to place the feature control frame.

  • A “Geometric Tolerance” annotation style is added to the model to control the appearance of feature control frames. The style uses a special GD&T font by Peter Kanold which can draw boxed characters, align those boxes, and construct the formatted strings required to display geometric tolerances correctly.

  • Double-clicking an existing feature control frame runs the GeometricToleranceEdit command to edit its contents. You can directly edit the content in its text object properties as well.
