Hello,

Some low cost packages to do package design, load planning and optimization. I have no experience with any of them, and in no particular order, but will eventually use one of them in the next few months:

There are also a group of higher cost options out there, but I won't bother researching those since I will not utilize those features for the foreseeable future.
