help! how do i draw this?

[JulienCatia]

Hello everyone

I wanted to ask for advice to those who are more experienced than me, i.e. to all, since they are at the beginnings

How do I draw the part of the wheel of this cutter tool? I mean the zig zag part
Thank you!

you draw the points in circles all around the central point and then you let us pass a spline

designs only one zig-zag and repeat it in circular series

I would probably start from a cylinder (piuttosto plate). I guess on the upper side I would have to draw one of those geometric figures, like a nut, which must be subtracted to the cylinder to create the zig zagatures, perhaps taking the dimensions with a caliber from the original. After that I would apply rotation to this element but using the option to generate an axial array. to which you can remove the material from the cylinder with a boolean operation. perform the same operation on the lower side of the cylinder but smoothly blurring the nut you created previously.

Another possibility, in my opinion the most appropriate, is to copy what is the probable method of production of the object, that is, you can start from a sheetmetal design sheet and create a mold with all those dice arranged in circle. Then you do a molding operation.
