How to create irregular 3D geometric pattern

joshuahume1 — Wed, 17 Aug 2022 19:19:44 GMT

I'm trying to create objects with irregular geometric patterns on their surface, sort of like the one on this sound diffuser panel I found on Amazon. I found a brute force way of making it work, by drawing it in 3d and then manually extruding literally every triangular face into one solid, but it takes forever to do that, and the file is unwieldy. Is there an easier way?

can you upload you model to see how what you do?

one way I can imagine would be to draw the base profile and then Loft the sketch to a point, but it would help to see what you tried already

Thanks, @stiller.design, here's the fusion file:

I couldn't figure out how to loft to a single point like that, is it possible?

In the fusion file, just to give you an idea of how I tried to do it, I imported a photo of that panel to use a reference, then I traced the outlines of the shapes. *

Then I created a construction plane, and added points for the top of each shape. My plan was to loft to this sketch, but I couldn't make that work. Then I moved sketch2 backwards in the history bar, so it was before sketch1. I then used sketch2 as a projection source and put those points into sketch1. After that I made construction lines in sketch1 of several heights, starting from the projected points. After that I connected the points of each shape to their corresponding center point. Finally I started extruding each shape downwards and joining them together. This is a long and tiresome process, so I only got halfway through before stopping.

Please note: I am not trying to make a copy of this product to sell or violate that company's copyrights etc.! I'm just using it for practice. I have my own designs I want to make - I just wanted to start with a reference.

Any help would be very much appreciated!

actually thats pretty straight forward:

-click loft

-select the base sketch

-select point

Huh, well, would you look at that?

I don't understand why I couldn't get that to work myself - I would have testified under oath I'd tried exactly what you said to do, but clearly I must not have done it right! How utterly baffling. Oh well, at least it works now.

Thanks very much!

@joshuahume1 LOL... no problem at all. Btw this also allows you to move the sketch points up and down as well using the move command
