If you use the Help menu from SketchUp, then choose the Knowledge Center and then type printing to scalein the search field and then click on the first hyper link, you shall eventually find this:

More specifically, if you are particularly interested in the surface or planar lock which this thread centers on, go to minute 5 of the second video listed above.

In this case, you can even link like this below - watch the #t=05m00s part at the end of the video link.

Unfortunately this does not work with the simple phpBB embed code.

Awsome thanks..
