I wish to use the 'vary sketch' option on a circular pattern feature but it is not showing up at all and I don't know why? I'm using an angular dimension as the direction driving the pattern. When I scroll this dimension, the sketch rotates as I would expect it to so I don't see what the fault is. I'm using a student edition of Solidworks but when I import a similar extraneous part the vary sketch option is there. I hope this makes sense. Thanks.
