I’m working on a project where I must find a section with the least volume of material per span. I’ve exported a simple box girder shape from SSD to a teddy file and parameterized the shape to change accordingly dependent on what the #STO values are. What I now want to do is test for a number of dimensions for each variable. For example STO#A 7000, 7500 ,8000. This would have to be done for a number of variables. The basic objective is to find the a cross section that uses the least amount of material. How can this be achieved? Is there a better way to go about this?
