I am wondering what is the best practice for creating an assembly in order to faster edit parts based on their interaction.

I used to create a different part per file as a new user, then the longer I am using solidworks, I see that maybe it would be best to output all my parts from solids created in one single (master part) file, with one single blueprint per plane. That way I only have one blueprint to change (in the master file) instead of creating many part files with many blueprints and multiplying the time it takes to edit things.

So from now on, I'm thinking to just insert my solids into a new part, then use that part in the assembly. I'm thinking it would be a cleaner, faster way to deal with changes.

What do you guys think? Am I on the right track?
