Title: From .stl to laser cutter
Post by: craighissett on October 29, 2015, 11:57:07 AM
Good morning/afternoon/evening everyone

I am currently putting together a small prototyping workstation using a Raspberry Pi, a 5" screen and an Arduino Mega.
Jinx ( http://www.robotrebels.org/index.php?action=profile;u=16 (http://www.robotrebels.org/index.php?action=profile;u=16) ) has been kind enough to design an enclosure for my idea, and it is bloody marvellous!

I have spoken to a gentleman on campus here at the College I work at, and have negotiated some free use of the laser cutter - good times!
All i need is to import the .stl files Jinx has kindly provided into an Adobe Illustrator template.

Can anyone suggest the best way to make this happen?

Thanks!

Does anyone use OpenSCAD? Apparently stls can be magixally crafted into 2D formats that would be usable for importing into Illustrator!

I'm not very good at openscad but if jinx can export the file as another format through sketchup (dxf or dwg) then I would be able to slice it into 2D for you easily with AutoCAD.

went looking at sketchup make  seeing if I could get either dxf or dwg out,  not a chance in hell without going pro or paying for a third party plugin.
 so am exploring openscad to abstract the dxf from stl. http://gilesbathgate.com/2010/06/23/extracting-2d-mendel-outlines-using-openscad/

Thanks again Jinx man.
If you email me that link I will ensure your frame parts get out in the cut queue tomorrow as a thank you

Hey Yahmez

Sorry for the slow update :)

Jinx's wonderfully converted dxf files are here:

Ha ha, if that's all that needs adjusting then you are a pure wizard.
You've put it together from vague direction and sketchy dimensions from me ha ha!

Now I just need to find somebody who can stick these in a facking Illustrator template!
I swear, we have so many gifted people here at the College, but none of them know a single thing outside of their realm. Nobody knows sketchup. Those who know illustrator use nothing else, so don't know how to import things.
 It's enough to drive even the most sane person MAD, I tells ya, MAAAAAD!!!

I am not sure if this will help but here it is.
I used to do a lot of 3D Modeling and Animation several years ago and many of the tools I used for it work with stl files. Here is a link to one of the tools I used for conversion of files and it allows you to convert a stl to dxf or dwg or 3ds or obj etc... http://www.micromouse.ca/ (http://www.micromouse.ca/)

Just a quick update.

Having an absolute nightmare trying to get these dxf files imported into Illustrator; they are not holding their dimensions and so are appearing to be really, really small.

Jinx - I'm so sorry - is there any chance you could export them as a .jpg from the sketchup file?
I have found a man with a saw who has said he will cut the parts if I can just print the parts off onto paper.

yea it can be done easy enough   .jpg you still have an issue of scaling?
why cant you scale up the ones in Illustrator. and give the the Illustrator user's a crack and whip, this is basic file import and somewhere  is/ should be a setting for size correction.  read the latest Illustrator a picky B&^%D.  so get them to grab inkscape  import the files than export them to Illustrator!!!

Cheers mate, I appreciate it.
Don't worry, the whip is still being cracked to get these f*ckers to get the job done; at least with the jpegs I'll be able to print them on paper for a cutting template in the mean time.
