skewed planes as datum features
skewed planes as datum features
(OP)
I'm working on a set of curvey parts that do not have the easy orthogonal surfaces to pick as datum features. There are flat surfaces that are functional but they are at skewed angles to each other. If I pick one for A and one for B does that lock up all degress of freedom? Also, how do you determine the origin and orientation of the datum ref frames from such datum features?

Can a hole whose axis does not intersect the line of intersection of A & B function as a tertiary datum feature? If so how would you locate the third plane of the DRF?
