Parallelism/Co-planarity tolerance (linear features)
Use parallelism as an orientation tolerance for cylinders, cones, and lines. Par-
allelism tolerancing compares the axial orientation of the selected feature to the
axis of a reference feature. The actual tolerance zone is a cylindrical area around
the axis of the tolerence feature. Specify the diameter of the cylindrical toler-
ance zone to create the tolerance.tolerancing compares the orientation of the
axis of the toleranced feature to a reference feature.
Use co-planarity as an orientation tolerance between planes. Two planes spaced
evenly apart with the same orientation are said to be co-planar.
To perform a parallelism tolerance
Step 1
Highlight the desired feature in the features list.
