While I have been a fan of his blog for awhile, I didn’t expect the sheer amount of personality that David Butts posses (as was evidenced by his Gold 2010 shaped glasses, his Mardi Gras bead prizes for audience participation.)
In his class MP314-1 Revit MEP Powerful tips and tricks is a must watch for anyone in the beginning to intermediate stages of using Revit MEP. When this is posted online be sure to watch and download the accompanying material.
Bonus: He usually posts a Kick @SS MEP Systems Project template to the class site that will go a long way towards helping you create an office standard template.
