FAKE ASSEMBLY

I LIKE to make some small welded assemblies using an alternative method without the need for mates, yet can easily be edited. Our shop doesn't like to see the welds shown so this works quite well.
The approach I use is to make a part with several bodies and then split the bodies up into their own separate files.

The way I like is when I make the initial model I intentionally make
each section piece where they don't merge together into each other.
This is accomplished by unchecking the "merge results" box as you
create and build up the solid model. What this does is create separate
"bodies" (solidworks expression) instead of one single huge part. Since there are
separate bodies then you can visually see your results with each body
having distinct seams. When you have everything where you like it, then
you just need to use the "split" feature command on your multi-bodied
part. All you have left is to individually name each body to create
separate files. This will create your parts and everything is where you
wanted it without putting it together like lego blocks like your
typical SolidWorks assembly.

Thought I haven't tryed this yet it seems like as much work if not more to simply build the hole thing in an assambly mode. The advantage I have with doing it that way is that when I get done everything is already in it's own file that can be used some where else if I want it to. In the Assambly mode there is a tool for building new parts right in the mode so you don't have to ever leave and make new parts to bring in to the assambly.
