Hi. Newbie in designing structural member here. I was supposed to design a simple lifting frame with 4 cables supporting the structure, but I kept on getting error report.
Can someone point-out on me what's wrong with my design. I actually tried to solve it by reading some forum here but no luck for me. It will be very helpful for me if someone can help me.
I attached the native file I'm working with.8764.Lifting Frame.STD

Also, if there will be people holding the structure with ropes at the bottom to guide it into place, you can add the supports at the necessary point(s) as follows:FIXED BUT FY MX MY MZwhat will produce the support reactions. Knowing the reaction value, You can judge how many additional supports will be needed to minimize such supports where people will be holding ropes.
