Nice to meet you guys, first post here. Hope it’s in the right place. I have been modeling some Gyroids recently, but I can’t improve it anymore, would appreciate some help. Below I described the steps to achieve the best result I got until now, so it might be easier to spot where the flaw/improvem…

That type of curvature control can also be important in strength, dynamics, fluid dynamics, cams, and all sorts of motion. Accelerating with a sharp in the path will lead to a shock, and the smoother it is, the more you can distribute the shock, making parts last longer, or for less turbulence in …

In other words from what I can tell my model would be as smooth if I manufactured it as a single surface because all the joint areas are tangent…again unless SW breaks that because it can’t create the single surface properly. The settings that you use in a feature do not always really control t…

[image] MJuric: Is it possible to do it on Octave or other free software? Guess I could find a way to work with imported STL files if the mesh quality is good [**] Yes i believe it is possible, as long as you could generate the “points” for the gyroid, you could convert them into STL using s…

The settings that you use in a feature do not always really control the outcome. That’s why we have the evaluation tools, especially the Deviation Analysis so we can tell numerically how far off from tangent a connection between faces really is. There is (almost) always a little tolerance between …

Ok, so what you’re telling me is that SW creates surfaces that aren’t really what they are supposed to be :smiley: :open_mouth: Well, when you’re lucky, they’re close. For example, I consider a model like this to be very close: image.png and one like this to be kind of marginal image.png O…

The purpose is that SW costs ~$4k, and NX costs ~$20k. Eventually that difference will pay for itself when you have to keep wrestling stuff like this. I haven’t used a higher end system in years. So does something like NX et al actually create surfaces as you would expect them to? If so I just …

[image] Frederick_Law: You can also do it with a Boundary if you draw lines from the center of the cube to the corners, and use those lines as Dir1 and use the arcs as a closed loop in Dir2. It may not have the tangency properties you’re looking for, but it’s an interesting way to make a shape. …

I am trying to make this model, but no matter what I cannot select all the 6 open groups. How did you do it? Not answering your question as I’m still on the smoothness issue. If you manage to make this piece aren’t you still going to have to piece it with a bunch of other pieces in order to ma…

Not answering your question as I’m still on the smoothness issue. If you manage to make this piece aren’t you still going to have to piece it with a bunch of other pieces in order to make the Gyroid? Isn’t that going to result in the same smoothness issues although fewer of them? Or is this a case…

Just my 2 cents, but I dont think there is way to create a PERFECT model in SOLIDWORKS for this kind of complex lattice minimal surface structure. You will have a little bit of imperfection here and there, especially at the joint. To get a theoretically perfect model, using a mathematical model t…

How do you make a rib with endpoints following cylindrical surfaces How To Questions

I am trying to make this rib follow the edge of both cylinders, but no matter the approach (using features) I never get a clean look. How would you do it? image.png I did it using surfaces, but I guess there is a easier way: image.png
