1-Create your cylinder
2-Create a CUT, ADVANCED, HELICAL SWEEP
2.1-For a sketching plane, create a datum through the axis of the
cylinder on an angle to another plane.
2.2-Sketch your sweep profile (make sure to have the profile's
extremities past the ends of the cylinder) and your centerline
(through the axis of the cylinder)
sketch your knurl cut section and finish the feature.
3-Copy the cut you created in the previous step. Make it independant
and use the same references.
3.1- Now redefine the copied cut. Redefine it's attributes, change
from Right-Handed to Left-Handed.
4-Patern the first cut and adjust the settings until you are
satisfied with the number of cuts created and the interval between
5-Pattern the other cut using the same increment and number of copies
you used for the first one.
NOTE: THIS TYPE OF FEATURE CREATION IS EXTREMELY HARDWARE INTENSIVE.
Your regeneration time will likely be very high. You may want to
create this geometry and then make a srinkwrap of it to lighten the
load on your computer when manipulating this part in an assembly
