Or know any good books? I am trying to teach myself how to do it rather than just using your sheet. thanks Reply Richard says: October 5, 2015 at 9:37 pm This 3D bolt group method is kind of lost in the mist of time. This sheet originally came out of the San Antonio interiors analysis industry and is at least 10 years old. You are not the first person to ask about this. Sadly we cannot give a firm reference for this method. Reply Leave a Reply Cancel replyYour email address will not be published.
