Problem of meshing a complex component

Hello,

I am having a problem of meshing the following complex component.

Whenever i tried to mesh different parts, it will show an warning " At least two bodies are interfering. Do you want to check interferece". Then it failed meshing.

I tried every method to merge them like joining parts and combing parts. SolidWorks allows me to do the joining parts but the problem is still there. As for combine feature, it does not allow me to combine them.

So i have no idea how to solve this problem.

I hope someone can give me some advise.

Thank you in advance.
