I've prepped files for laser cutting, but never been involved with pricing or arranging for the work. Looking at the Epicurus file (I'm using Rhino 6) I have a couple of comments: - From my experience it's normal to provide a 2D file consisting of closed curves (linework). The material thickness is specified in the written order and so there is no need to model the thickness of the finished product. You can include notes as to thickness and material in the file if that's helpful. - The thickness…

Hi Elli Elli, I'll see what I can do. I won't be at my computer for a few hours but at the very least I can indicate the floaters in the stl files and also show them on a jpg. Not sure if I can convert to AI or EPS so I'll look into that at that time.

Elli here's the fruit of my efforts.... It might be that the things most useful to your graphist are these two jpgs showing the "floaters" in red. The images on the left are the meshes that were in the stl files that you attached; the images on the right are of curves that I created from the meshes. These images are in the attached zipped folders, along with conversions to ai and dwg. Each ai file has the meshes and the curves as shown in the jpgs. Each dwg file has the curves, scaled up to 35"…

It also looks like some of the outlines are quite thin when it comes to holding the piece together structurally. That's probably another adjustment the artist will have to make. It's quite a complicated project and, as you say Cassius, it would help to have some fairly simple but accurate graphics to work from. There are actually two design problems to solve: 1) the design of the portraits, and 2) designing the outlines, creases and shadows in a way that they will hold the cut material firmly to…
