Generative design - polymorphic adjustments - building on skeletal structure

[johndellostritto214]

Generative design can  meet it's full potential by having a tool set of polymorphic controls. Cylindrify is one of the new controls in that toolset that flesh out spindly members in GD model. High stresses occur at joints of connecting members, this is where control of generating 3D manifold fillets occurs.  It is possible to visualize and initiate modification of these fillets by fleshing out the skeletal vector structure defined by the GD FEA first pass . In a do loop fashion add incrementally fillet material going from radial/circular configuration to elliptical/parabolic configuration, if required . Adding the minimum material to where the stress is located while using a weight metric with each iteration as boundary parameter . Not only should the Radius/ellipse increase in size but cross thickness could  increase as well. Symmetrical parts should have features transform in pairs or mirroring duplicates as required. The resulting curves and transitions should be smooth and tangent looking natural and organic. 

Also this should meet desired complexity goal of minimum surface patches for enclosed part envelope

These polymorphic controls should assist  designing a part that is structurally strong, fully functioning and aesthetically pleasing to the eye like a well designed piece of modern art.

Feel free to contact me if you have questions to understand this concept or wish to discuss

In the article Modeling Deep Dive by John Helfen dated 7 July,  Reference objects are features pulled from assemblies onto new build parts. This process is what's needed in Incremental translation to show worst case hole location ) ie the four cardinal points). You can copy the hole data put it on a sketch and then MOUSE CLICK translate hole(s) based on standard GD&T position location box callout. You will see the worst case condition and a flash window telling you how much interference exists, the  next hole size that provides clearance and new GD&T position box callout.  This should work for other features as well.

Hi @johndellostritto214 - 

Thanks for your recent contributions on geometry improvements for generative design outcomes. As you have mentioned, the Cylindrify tool has gone a long way in helping users clean up and normalize the topology of a generatively designed geometry. If you haven't looked at the Smooth tool in T-Splines, I would suggest giving it a look, as it too was built to help out when working with generatively designed geometry. While we have these modification tools, we are also hard at work and have been making incremental improvements to the smoothness of our shapes and the quality of our junctions between generated geometry and originally modeled preserve geometry. This latter area is a key area of focus at the moment, as we know that these transitions often create stress concentrations, leaving the user to clean it up manually, which is typically a non-trivial task. I would welcome any other feedback you have on generative design in Fusion 360 and to learn more about how you are using the tool. 

Thanks,

Thanks for replying Mike,
I have a portfolio of ideas on CAD concepts. Do you still live in
Pittsburgh, PA? If so I live In ohio about a six hour drive from PItt, PA.
and would like to meet sometime.
Let me know if such meeting is possible. Weekends - three days Friday - Sat
Sun are best for me.

Thanks,
John
