Web16 nov. 2024 · Perpendicularity is a very common callout in GD&T due to its simplicity and usefulness. Both surface and axis perpendicularity are often used in engineering drawings to guarantee the desired perpendicularity. In its surface form, perpendicularity can control planar as well as curved surfaces. Web13 apr. 2024 · CLos (Mechanical) (OP) 13 Apr 23 18:09. I suppose my datums would be the bottom face and the center axis of the facing top/bottom holes. I'm mounting something to the face and the hole on each side; and I care about the pointing accuracy of this assembly. The holes are meant to be pilot holes, so I care about the diameter and straightness.
