I use one of the best kept secrets in the CAD industry, IronCAD. I was introduced to this software about 10 years ago from a mentor I was lucky enough to meet. I’m sure the information he’s shared with me over the years is priceless. The introduction to IronCAD is among those nuggets of priceless information. IronCAD’s slogan (or tagline) is Design better, faster. I believe this is true. It has a no constraints intellifeature process that is very free flowing. This video tutorial goes over how to create attachment points for building assemblies fast. For this tutorial I use my HAAS catalog. It is small right now but it grows monthly, HAAS will release solids of their product upon request!
