![]() ![]() Create obstacle geometry: Again, working with the base model, create any obstacle geometry needed.Be sure to include any needed extra grind/machine stock, fluid containment walls, or other "oddball" preserves. bolt bosses, flanges, etc.,) as new bodies to be used by the generative process. Create preserve geometry: Start with the existing base model, be it a single part or a full assembly.moving parts, changing loads, etc.,)? What is my end goal - is it weight/material reduction, performance enhancement, aesthetics, or some other metric improvement? Ask yourself: How does the new part(s) interact with the greater assembly? What kind of manufacturing, assembly, or other practical considerations is present? Are there any dynamics at play (e.g. Identify the problem domain and gather information: Spend some time thinking about the problem at hand and how it fits into the greater context of your operation.This is an example of a common design process used to develop and evaluate a design chosen to be run through a Generative Design software. Generative design allows you to compare these options all in one place, then simply download the desired solution that best fits your needs. Traditional design requires that you review the part design, the part analysis, and the manufacturing options to decide which design fits your specific needs. With generative design, you select from a list of options to derive results based on the options selected.Īt this point, you begin comparing the results to decide what is the best option to use. With traditional design, the manufacturing process is typically determined by the design of the part. The manufacturing process of the part is also not always known and can range from machined, cast, fabricated or printed. With generative design, you assign multiple materials so that you can optimize your design process. You start with a single material, then adjust based on the outcome of the analysis. In a traditional design setting, the material is not necessarily known until the part is created. ![]() The material that is used for the part design can vary and has a direct effect on the strength of the part. You will apply loads and constraints to these bodies to help define the function of the part. With generative design, you build bodies that represent preserved areas, obstacles, and starting shapes. In traditional design methods, you take the information you know and mix that with traditional shapes to develop a couple of concepts then you run an analysis on each iteration to look for the best performance. The function of the part is a combination of loads and forces that are applied and known physical constraints that restrict the space and mounting points. Generative Product Design breaks down into four components: the function of the part, materials used, the manufacturing process, and how it needs to perform. It tests and learns from each iteration to ascertain what works and what doesn’t. Unlike topology optimization, the software explores all the possible permutations of a solution, quickly generating design alternatives. Designers or engineers input design goals into generative software, along with parameters such as materials, manufacturing methods, and cost constraints. Generative Design mimics nature’s evolutionary approach to design. Want to learn more? Take this and other manufacturing courses from IMAGINiT instructors at Autodesk University 2019!
