## creating a lattice of a shape from another shape

 Greetings! i've perused the OpenSCAD forums but not posted before. I'm trying to figure out how to use OpenSCAD to create s say a cube or a wall but make the lattice of only the complete contents of another. Similar to the "pattern" feature of meshmixer. Basically i want to be able to take any complex or even an imported STL and make it be "made of" whole kelvin cells like this - https://pressurevesseltech.asmedigitalcollection.asme.org/data/journals/jpvtas/28540/029004jpv1.jpeg I can figure out how to make it work for simple shapes with known geometries but not with complex shapes like benchy. Any suggestions? can this be done with openscad? cheers! _______________________________________________ OpenSCAD mailing list [hidden email] http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org

## Re: creating a lattice of a shape from another shape

 That was my first thought and i gave it a go but there was no way to ensure that the cells were all complete, most of the cells on the edges were all partial which would be ok except the cells are only strong when they're complete.

Is that a good description of what you are trying to achieve? If so, then it just becomes a matter of how to write code to create the lattice.

 In reply to this post by mister.koz As doug says OpenSCAD might not be the right app for you. I have seen this done using manifold lab version of Wings3d. here is some info: - on the general manifold labs plugin - http://www.wings3d.com/forum/forumdisplay.php?fid=14 - scroll through here for something that looks similar - https://www.youtube.com/user/ggaliens/videos - like: https://www.youtube.com/watch?v=A6eavvoudMI - OR https://www.youtube.com/watch?v=Y1HGdvgMbxw&list=PL8liErXtlMzcOjbisq10xee48P5MkX7Zs On 7/1/2018 12:55 AM, adam purdie wrote: Greetings! i've perused the OpenSCAD forums but not posted before.
