Over the last 24 hours I cannot tell you all how much I have enjoyed the http://tech.groups.yahoo.com/group/solidworks/! online group. My 2nd semester class was able to get much needed information on how to spec out a helical gear on a CAD print in a matter of minutes (About 78) and Matthew Lorono–one of the fine person’s moderating the group with me–recently launched the SolidWorks Legion blog site. There is currently a post from him about Design with intent and Horizontal Modeling which I found to be fantastic. I will question him on a couple of his points, but his intent in this post is loud and clear. Use best modeling practices to ensure changeability, ease of creation and an overall stable CAD database for all to use.
