Diamond shapes
Diamond shapes
(OP)
OK I understand diamond shapes are not a big deal... on a flat surface.
I was asked to find a solution, but I am not having any luck. Hoping maybe someone else has some ideas on how to do this.
I have tired surfacing, bodies cut with a surface and because of the 9.289 radius from top to bottom and it throws everything off.
The image shows the part. The bottom row is on a flat surface, but the rest are on that radial face.
Anyone have any suggestions?

Cut-Sweep a groove
Mirror the groove (or cut-sweep other direction)
Circular-Pattern the grooves
RE: Diamond shapes
Cut the grooves instead of extruding the diamonds.
The attached file shows it on a cylindrical part. Not too bad.
On the next post I will do the same for a curved surface and you can see how it distorts it.

RE: Diamond shapes
If you notice on your b part which represents our model better. The Diamonds change in size, they are not staying uniform. They have to stay uniformed... if this can't be done, that's fine I just have to show why it can't be performed and thus far I am not seeing a way to control this.
Thanks guys!

RE: Diamond shapes
The image in your OP shows a much greater curvature than the image in the photo you later posted. Your last post indicates the diamonds must stay the same size. They are approximately the same size in the photo, but as the surface curves more something will have to give. I am guessing the number of diamond tips must be the same at both ends of the pattern and that the tips must close to form complete (whole) diamonds, as indicated in the photo. If you were to measure the tip-tip spacing they will be quite different from one end of the pattern to the other. So, to have an equal number of whole diamonds on each end they will, by definition, not be the same size.
What is the purpose of these diamonds and how will they be formed? (I see what looks like a parting line in the photo so that would indicate the part is molded. I am guessing the diamonds are for appearance or grip.)

RE: Diamond shapes
The first image is of my actual part, the second image is to to show you how we need the diamonds to be in a uniformed or similiar to that 2nd image. However because of the large radius of the actual file I am working on the diamonds become not uniformed or run into each other.
I don't think what I was asked to do can actually be done in a "Molding" Process with the 9.289 Radius surface being the foundation of the diamond knurl shape.
I have tried many different methods to try and achieve this, and I always end up with a problem with the final solution. They are not uniformed, or they are running into each other near the top of the closure.
Thanks for taking time to look at this, been driving me nuts all day.
