The document summarizes the results of optimizing member sizes for a structural model through multiple iterations. It shows graphs of the unity check values and structure weight decreasing with each iteration. The overall conclusion is that the initial member sizes selected were conservative, minimal changes occurred after the second iteration, and the final optimized model had 20% of its weight from primary structure and 36% of the total module weight from structure. The runtime for each iteration was 3 minutes for SACS and 2 minutes for the macro.
