For those of you that are interested.  I just posted up a new website that combines my blog (www.robrodriguez.com) site and my business site (www.axiscadsolutions.com) into one.  All the presentations and blog posts from the old site are there as well as business information.  If you are looking for the presentations previously found on www.robrodriguez.com you can find them here now http://www.axiscadsolutions.com/downloads/
