Fold Over Elastic
I'm trying to recreate fold over elastic (as used on the edges of underwear), I used the fold tool to place the pattern piece over the raw edge.
- particle distance of 1
- addtnl thickness collision 1
With these settings, the bottom pic is the best I can get, its very slow to simulate and the pattern pieces are still fighting. Any tips on how to achieve this?

Trudy, the first question that comes to mind is why do you need to encase an elastic band in CLO? It is clear why one needs that in real life but in CLO you are virtualizing reality. For this reason there are many shortcuts (like sewing) to represent what happens in reality.
With that in mind and with many years of experience using this software, I can tell you it is very hard to do what you are trying to do and the cost/benefit relation is going to lean towards the cost part. My suggestion is to use other techniques to simulate the elastic and not encase it. Especially on such small pieces.
If you insist on doing this, you should make sure the Additional Thickness Collision is low (~0.5 mm) between the pieces you are encasing, then do not fold, but have the elastic sandwiched by the outer pieces and a self piece of fabric cut like the elastic. Use the Set Sublayer feature when stitching, so you achieve stability.
I hope this helps.

Hi P, thanks for your response, I guess I'm tying to make a useable pattern, and show the details of how this pattern actually comes together. I have tried using the binding tool, but it does not look good at the corners of the pattern pieces, it cuts off the binding at a 90 deg angle and does not got all the way to the curved edge. It also does not show that the raw edge should be encased. I want to be able to show the construction techniques used in this garment with fold over elastic. I'll try the technique suggested above, this does present a problem I've been finding with Clo though, the pattern will no longer be representative of the real physical pattern.

Trudy, as I see it ignoring seam allowances when possible, is always a reasonable method to simplify a garment. Once the raw edge is bound, that's really just a seam allowance. In real life it's not necessary to know exactly how the edge gets compressed inside the fold over elastic because you have this tidy binding that hides all that. No different with a simulation. You really don't want to calculate layers you'll never see, when there are better ways to get the look of a garment with an elastic trim. You can apply elastic properties to get the fit, and textures to get the look. That's just the thinking I've come around to, it is an adjustment figuring out which parts of physical sewing are essential to simulation, and I understand the urge to keep things as analogous as possible.
