Features that are critical to the function 2. Bonus tolerance equals the difference between the actual feature size and the MMC of the feature. From the figure, we see that, The points A, S, and R lie in the same line but Q does not lie in the same line. Parallelism is a 3D GD&T orientation tolerance which maintains that two part features are parallel to each other. If you want to create a note with multiple leaders, you can pre-select the edges, vertices, or faces, then create the note. 1%. S.
