Having trouble mating 2 parts in an assembly

paul_bartlett

I have these 2 parts  aligned almost the way they need to be mated. I can not for the life of me figure out what mates to use. I've used a lot of different ones and get weird results every time. The groves won't all line up but that's something I can probably fix. Once these are mated properly I will mate 2 of these assemblies in a similar fashion so they create a continuous loop (Ribbon)

Try using a fastened mate. The fasten mate should cover a large percentage of your mating needs.

What Glen says about the mate — thumbs up

If you are curious about an easier way to model in order to get all the ribs aligned in the assembly, take a look at this

Everything done from the center out.

This is absolutely amazing. I will to have to do some serious studying of this model to see how you did it. Thank you
