PARTS TO ASSEMBLY

Hi Guys,

I have created a wheel with many features but they are created as Part file.

What would be the best way to convert that part file into to assembly file and convert all those features into different Part files.

My first instinct is to manually create part files from that single part file, do a Save As into many files, then create assembly, then put them together.

is there a better way?
