when you click on a specific tutorial, a new page opens. you'll find a green rectangle labeled "download". Under that, will be a couple advertisements. then, under those, you will find a curved green arrow, along with the download link.
There is one that deals with top down design [url]http://www.cadfamily.com/download/CAD/Proe/TopDown%20Design. PDF[/url], and I wonder if anyone has the files for the boom-box that are needed for this tutorial. I's a long shot because it's from way back, but maybe someone can help me out? Please PM me with those files. TIA
