I've been skulking around the forum and I keep running into this:

"You do not have the required permissions to view the files attached to this post."

What does this mean?

New here,also new with SketchUp, what I am trying to do is draw a simple isometric one line plumbing drawing without needing to create my own fittings, that would take waaay too much time, hope someone has a solution, thanks.

I've enclosed an example.
