Computer-Automated Design is the process of design by computer and without human intervention. Studies on simultaneous size, shape, and topology optimization show that computer-aided design is preparing to replace computer-aided design. Most studies presented on simultaneous size, shape, and topology optimization measure the performance of the proposed optimization method (or method improvement) with popular test problems. These test problems are designed using a number of simplifications to allow them to be solved in an acceptable time; and therefore they cannot represent real -world problems. Moreover, in most of the mentioned problems, only structural constraints are considered and manufacturing constraints are neglected. Structural constraints are related to the material used (stress, strain, etc.) and the behavior of the structural system (node displacement, global buckling, etc.). On the other hand, manufacturing constraints are the constraints that are related to manufacturing, such as the absence of intersecting elements in the system and not connecting many elements to a node. In this study, the real computational load of computer-automated design of planar truss systems is discussed. What is meant by the expression "real computational load" here is the computational effort spent searching for near -optimal solutions to design problems, where there are no simplifying constraints that are not found in real -world problems, and where manufacturing constraints are taken into account as well as structural constraints. Numerical experiments were performed using a parameterless metaheuristic algorithm, which has been proved by previous studies to be suitable for the optimization of truss systems, and the results are discussed.
