    • It is important to use the Associated Objects control to select the correct geometry reference (typically a surface or a hole) and associate it with the annotation you are creating. Note that aPriori does not read PMI associated on edges.

    • Fill in the fields on the Surface Finish dialog. Enter use the Roughness (a) field.

    • If the value that you want is not provided by the dropdown menu, type in the value such as “Ra 1.5” or “Rz 10”. Image
