What is the best possible way to draw this part
This is a cylindrical part and i want to know what is the easiest possible way to draw this part.
As you can see two types of slots are given on its circumference, one is helical and other is in taper and both are joint. start of helical slot merges with the adjacent tapered slot which shares the start with other helical slot and pattern repeats its self.
There should be 12 sets of these slots on its circumference in a span of 360 degree
for better understanding see the pictures take dimensions whatever you like.
