The way Shape Generator works is consistent with the way you’d use topology optimization in specialized CAE software, but with a simpler interface.įorceEffect, previously available as an iPad app, also appears in this update as an integrated 2D simulation application. Since Shape Generator is embedded inside Inventor, the user can overlay optimized geometry proposed by the software to the original part, making it easier to identify the regions where further trims and cuts can be made without affecting the part’s structural integrity. In the initial incarnation, Shape Generator focuses on “structurally efficient lightweight parts,” explained Hartog. Introducing optimization at the CAD design phase brings the art of lightweighting closer to the conceptual design phase. In that respect, Autodesk Inventor may be breaking new grounds with the introduction of Shape Generator. However, it’s rarely integrated in general-purpose CAD programs. Certain simulation and analysis packages also offer the function. Special software like solidThinking Inspire lets you perform topology optimization. “Our approach is to put it in CAD so it can benefit the conceptual design phase.” What’s different about this is, it’s integrated into a mainstream CAD platform,” said Jonathan den Hartog, a Autodesk product manager for Autodesk Inventor.
“Topology optimization has been around, used mainly by the analysts community with CAE (computer-aided engineering) tools or special tools. The geometry is optimized based on user input, such as loading condition, anticipated pressure, and targeted weight reduction threshold. Like Autodesk Within, Shape Generator relies on Autodesk Nastran as its simulation engine to perform stress analysis behind the scene, then proposes the best-or optimal-geometry for the project. Another variant appears in the latest update to Autodesk Inventor as Shape Generator, a topology optimization function embedded in Inventor’s CAD modeling environment. Then it explores all the possible permutations of the solution through successive generations, until the best one is found.” That sums up what Autodesk calls “Generative Design.”Ī variant of Generative Design can be seen in Autodesk Within, which automatically generates lattice structures that fit user-defined geometric volumes. Inside Mandalay Bay, speaking to the crowd at Autodesk University 2014, Kowalski said, “ starts with your goal. It’s a vision that Autodesk CTO Jeff Kowalski shared a year ago. Autodesk ForceEffect, previously available on iPad, is now brought into Inventor.
