Old, but gold! SW, 6 features (it can be done with 4 features).

The tutorial video is unavailable.

Inventor. Took some thought.

Not very familiar with it took me a lot of steps.

I tried many times but the intersecting hole in the middle still didn't work, maybe something went wrongI tried many times but the intersecting hole in the middle still didn't work, maybe something went wrong

In detail, this ring is a bit different

Break it down more into smaller steps. Note the array of the spherical feature does not use an angle evenly divisible into 360 degrees. If there are 16 holes in the array, then the angle would be 360/15.5

The final step is to do a circular pattern of the whole thing with two copies.

There are other methods you can use.

I believe you have two separate interlocking rings. The challenge has a single ring that makes two loops

This method is faster,great

OK,I'll try, thanks

Bob, you are right, I was misled by the title of the post. The usual mobius ring is a 180 degree turn and a 360 degree bend, I thought it was just a double profile. Looking more closely, I realized that this is a double mobius ring - a turn of 180 degrees and a bend of 720 degrees.

Next time I will read the terms and conditions more carefully.

Of course, 720 degree bend can't be done with "flex" commands due to selfintersect of surfaces, but i still used "flex" commands and circular array to do it. I think this method is the most suitable for such design things. You can loop any non-repeating pattern or even an inscription.

You are absolutely right!

You are correct. A mobius loop has just a single loop. Took me a while to see it.

Inventor doesn't have this flex or twist capability. Wish it did.
