Today I Learned - DMIS FEAT
This syntax defines the nominal position, direction, and size of the feature if required, i.e. circle, cylinder. The name of the feature will then be used in measurements, constructions, reporting, etc...
The FEAT syntax will at a minimum require a coordinate location and normal vector directions. These location may be defined in CART (X, Y, Z) or POL (R, A, H).
The vector defines the direction of a feature using three values (I, J, K)
I = the cosine of the angle from the X axis to the feature normal axis
J = the cosine of the angle from the Y axis to the feature normal axis
K = the cosine of the angle from the Z axis to the feature normal axis
If this surface is a compound angle for example in both the X and Z axis and is 45 degrees from each axis (45 degrees in X and 45 degrees in Z). So if the surface angle to the X axis is 45 degrees then the cosine would be 0.707 and the cosine in Z would also be 0.707 then the command would be.
