Slots, circular pattern and taper

[Anonymous]

Hello,

I am trying to create circular pattern of slots where the slot height is some fixed value smaller than the previous. Is there a formula within parameters I can use to accomplish this task? In the image below you see that the first slot height is 13, the next is 13-0.21 and so on. I Please help! My back is hurting sitting here dimensioning and renaming parameters. Is there an easier way. It would be nice if circular pattern could all one to taper slots in an associative way if that makes sense.

 I posted this very late in the night hence the errors. To clarify, I am want to create a circular pattern of slots where the next slot in the pattern is a set value smaller than the previous. To do this I redimension each slot. So the Slot1 = 13 (user parameter). Slot2 = Slot1 - Slot_taper (another user parameter),Slot3 = Slot2-Slot_taper, etc. I am wondering of there is a formula I can use to simplify this task.

Hi! If you want to create a sketch pattern like that. I cannot think of any easier way than what you are attempting. Can I ask what you want to do with the sketch? Are you trying to project these slot profiles to the surface. Or, they will split or cut the surface in sketch normal direction? If yes, there might be better ways to do that than creating the profiles in a sketch.

Many thanks!
