Have you designed pipings using  the Solidworks Weldments?

Before I work with SW Premium, I had to use Solidworks basic a lot of years.

Now, sometimes I prefer design the pipes using Weldments before Routing. I know some companies that they design the pipes using bottom-up design, even worst, they don't use the design library, and they have to copy and rename the same files of elbows, flanges and all kind of accesories everytime they do a new project.

When I work with some of these companies, I design the pipes with Solidworks Weldments, so all pipes and elbows are inside the same part file.
