Thank you for this webinar. Q: your layout of your SubD last has only a few control points (grips). Minimizing the amount of grips is good practice and makes modeling much easier. But does your last has enough grips to define the shape of the last in every detail? One of the disadvantages of SubD modeling in Rhino is that adding more vertices to the control mesh of the SubD (when you discover you can not create all the details you need) disrupts your carefully shaped last.
Thank you Erik, for attending and your questions. You are totally right, some lasts would need more faces to achieve the desired shape. This is a simple last, but for sure you should add more faces and this will affect some neighbors. But still, you can keep controlling using slide edges or removing some extra edges. Maybe some extra details should be applied when is converted to NURBS. You had another question during the webinar, I could not reply. It was about metadata or metamaterials? Could you please write it down here? Thanks.
@@ReneMedel Thanks René, I totally agree. My question was indeed about Metamaterials. When you create an infill of lattices for let's say an arch support insole, can you keep the directions of the generated lattices follow the forces on the insole, like the spongiosa in bone? Someone answered that Ntopology can achieve that, maybe you know more about this. Regards, Erik
@@podotools Interesting question, Erik. The short answer would be yes. In Grasshopper you could define those directions in many ways, like attracting points or following the normal of a surface. The organic lattices are usually stochastic, so it's not so easy to set directions, but maybe the density of populating points could also act like a bone structure.
Hi Rene, I am very interesting your 3d print sandal, I do foam work over then 30 years, I had tried 30% size 3d print model then foam to 100% with EVA and TPU.
Interesting, but SubD always seems like Play-Doh. Great for the soft shape of a shoe last, but lacking distinction for other surfaces. You can quickly get to 80-90% of a design, but no way to reach 100% In my opinion.
Thank you for the invite to talk and for sharing the recording.
I will try to reply all your questions here.
Fantastic webcast! Very insightful.
Thank you for this webinar.

Hi michaelle, thanks.
Do you mean a hybrid production between AM and molding? That’s interesting
@@ReneMedel How do I show my 3d printing and foam to you?
please tutorial how to draw shoe last from the begining on rhino 3D.
I'll share it with our videotutorials team.
Do you have a tutorial that shows how to design a upper and sole around the last?
I don’t have, but you can check the videos from design & develop about Botcha and Jevero in Rhino
nice
非常厲害
What is the plugin you use for footwear design ?
I did not show any plugin, but for footwear some plugins like Orang and Jevero/Botcha are very helpful

Well, in general modeling we need to find the sweet spot between different topologies. The best combination between SubD, NURBS and meshes
