Beautiful Complex Geometry possible?

oooo I like them! Mine was based off of creating different designs only using points around the edge of a circle and straight lines. Lots of cool effects you can do with that and varying the number of points on the edge, and then choosing which lines to draw.

I really like the other effects you are putting in yours! And combining them to make yet MORE cool designs together! Very cool

oh I’ll have to try that.

thats really beautiful, like a inner 3d print, reminded me of ERIC STANDLEY that does this with paper

What you started to draw is known as the most beautiful shape in mathematics, its called simply E8.

a 2 dimential projection of two 4 dimensional object thats a 8 dimensional lattice that could be perhaps the very nature of our reality according to emergence theory :joy:

I had no idea I was doing something so fancy sounding :wink:

It’s just something I came up with when I was a young kid when I was bored in class. Drew a Circle, did the normal crossed lines. Then bisected those lines so it was in 8 pieces, then drew lines from where the lines intersected the circle to the other ones. It grew from there to what you see now.

Never knew it had a fancy name or mathematical meaning to it! Thanks!

reality is so simple you can draw it on sand with a stick, rope.

don’t ever question your ability to create beautiful things :smiley:

play with connecting 2d shapes from points using the circle tool on sketchup and changing the number fo segments, you will unlock the universe.


Be careful with something this dense, this is how fires get started. Watch the job carefully and be ready if it ignites.

I can see design playtime in my future! (or is that reality bending right now?!!)

im still open for any suggestions on how to proceed with complex files like the ones I’ve shared on the we transfer link :pray:

my work’s firewall is blocking me from opening it here, I’ll have to wait till I get home to potentially play with it.

It’s a beautiful design, i wish you much success with it!

I do hope you are aware that this forum is open to the world for viewing (and I assume that applies to links and files as well), even though only Glowforge owners and authorized users can post. So you should avoid sharing links and files that you want to keep private.


thank you for your kind words

oops i didn’t know that, i will delete it once i find a solution


you are going to want to rasterize it. That is a very complex vector (75mb of pure vectors), and the main center shape has been expanded, so the laser will run both sides of each of those thicker lines. That main center shape alone has 4,019,020 nodes… I don’t know the GF’s upper limit for node counts, but I think 4 million is too many.
It is also almost 40" square, which is a little large for the bed.
Even if it were able to load and process, it would spend a whole lot of time revisiting areas, making the print time waay longer. There is also a clipping path in there (in the layer labeled “0”), and the GF does not like clipping paths.


Looking at the design and perhaps broken out to two or three layers that you cut on clear acrylic and project on to a plain inner dome perhaps as an array of LEDs and perhaps with stuff moving and or changing colors. They have the parts built for projecting Santa’s or pumpkins but what you are doing could be so much more.

the rasterized file, engraved on BB ply at 11" square:

(click on the image to see it full size)




one completely random thing you might consider is using multiple sheets of 1/16 clear acrylic.

break your design elements into multiple layers. if you divided it into 8 layers, you could etch on 8 different sheets and sandwich them together and use something to side light the resulting 1/2" slab.

or maybe if you reversed every other layer, you could etch on both sides of 1/16 acrylic and sandwich the 8 layers on 4 sheets and only be 1/4" thick.

or it may be a complete fail. but i’m kinda thinking about the piece that @xabbess did here.


:scream: is this a render or a real image ?

how did you manage you do it ? :heart_eyes:


This is a cell phone picture of a real engraved image from the file that you designed.

I opened the PDF in Adobe Illustrator, and, after examining it, exported it as a PNG.

Then I opened the PNG in Illustrator, resized it to 11" (to fit in the bed and the GFUI). I added an additional 11" square around your art, in red, to cut the shape out of my 12" sq material (3mm baltic birch plywood)

Then I saved the file as an SVG, which I loaded into the GFUI.

My settings were pretty simple, based on plenty of previous knowledge of this particular material.
(but I can’t share them here or the thread will get moved)

Then I hit print and let the laser do it’s thing for 2 hours.

I PMd you a jpg copy of the rasterized file, and the settings that i used. The PNG was too large to send here.
