3D Texture

antoine_richermoz

Hi, I design parts for 3D printing and I this is what I would like to to :

You see this very fine surface pattern ?
This is what I would like to do in Onshape (or other software)
Do you know how to do it ?

Pretty cool ! @mbartlett21

@antonie_richermoz - if we number your images 1 -> n starting from the top, here are some thoughts;

1) The end caps are simple 2D patterns. The grill is a simple fill pattern (https://cad.onshape.com/documents/57361ad4e4b00e5012c3857c/v/eb8bfe2edd984a315033e6e2/e/14aa44d127806651b248b9c6)

2) This is doable - it's pretty manual unless you want to write a custom feature to automate this.

3) The end caps and grill can be made with the 'lighten' feature. The facetization can be created manually, or automated with a custom feature. (https://cad.onshape.com/documents/573f7d70e4b0fddafb52148c/v/a8a36f6d743269e1b6886711/e/2dc22a6a95896a5243812d07)

4) The ornate grill is a simple pattern. The end caps are not something that a b-rep modeller can easily handle. This type of geometry is not something that you will want to do in Onshape (or any other modeller - eg SolidWorks)

Another custom feature that may help is the surface pattern feature.

philip_thomas this is really cool ! Thanks a lot

So if b-rep modeler can't really do this what type of software can ?

And also I think you messed up your last link.

@antoine_richermoz - sorry about that - i fixed the link.

The best answer i can give is not really a good answer. Those kinds of very small scale perturbations are very hard to generate.
However you go about it, the end result is likely to be simply an STL file.

The workflow will probably include some elements of;

Either a brep or surface modeller generating the feet and lion heads
Perhaps a polygonal modeller for the perturbations- eg 3D -studio max or Mesh Mixer (and to combine the feet and heads)
Perhaps a generative solution (eg Rhino + grasshopper).
Perhaps a 3D scan of a hand carded model.

Again - that last case is very hard - how did you make the geometry shown?

This is really interesting thanks a lot !
I think the surface pattern will suit my needs. 

I did not make any of the example above, this are from a Bluetooth speaker from a company named V-Moda, and I thought their designs were really creative.

                            How do you make the pyramid? I used the rollback tool to see but when I come to the Pyramid it only shows a square.

@miyah_hofer
You can extrude a square with draft 45 degrees inwards. Just make sure you extrude it enough

                         How do you only select the diamond to Linear.
