Loving the ease of making slices for laser-cutting - thanks so much for the tool! But I am struggling to get the slices aligned. Is there a function so we generate an outline on the bottom piece so we know exactly where the next one goes, e.g. like this: ![image](https://forum.grid.space/uploads/default/original/1X/8c4b104577316ce77a57bce6ba5e5474aee694d0.png) i.e. blue would cut, red would score, and we could use the scored lines to align perfectly the next layer. thanks! -mak ---

Hi @mak and welcome! Can you do something as simple as add one or two pin holes that goes through the entire stack? ---

Thanks @stewart. Yes, but it would require a lot of pinholes for anything more complex, such as ![image](https://forum.grid.space/uploads/default/original/1X/9cfdb6565b30d9f5490fcbfe86c1eb9a800bbff1.jpeg) and I think I’d lose track of which pinhole went where. The previous slicer I used was a now-defunct plugin for Fusion360 which had this function built-in, and I didn’t realise how important it was until I tried making a topographical map without it! ---

oh, wow. totally makes sense for that 🙂 let me take a look at the code and see if I can whip something up. the easiest way to do this is with SVG colors, if you’re using that output. ---

Awesome, that would be amazing. Colored SVG is perfect ---

@mak I didn’t forget about this. the latest dev release `3.1.D7` has a new option under output ![Screen Shot 2021-12-07 at 7.31.58 PM](https://forum.grid.space/uploads/default/original/1X/47e63e61bfa63b5d38a4b81421b10514bfb89507.png) for a model like this ![Screen Shot 2021-12-07 at 7.32.53 PM](https://forum.grid.space/uploads/default/original/1X/438d94ef79bebcaf217c413e26f78ae55506fb07.png) it adds a different color mark so you can enable a different laser power for marking stacks ![Screen Shot 2021-12-07 at 7.32.59 PM](https://forum.grid.space/uploads/default/original/1X/ee3cfde61199812aa455b040f4c504294bd9c0f5.jpeg) ---

Hi @stewart - thanks again for adding this facility. I wrote an instructable on it, see [Pending Review - Instructables](https://www.instructables.com/3D-Contour-Map/) ---

awesome. I assume you’ve confirmed it works then 🙂 ---

use the arrow keys to rotate the object to lay horizontally ---

I mean 3D DXF output rather then a a flat layout as in the following ![image](https://forum.grid.space/uploads/default/original/2X/e/ed95bacba2e2cae89b32bd9ca0e3f1b735c123a7.png) ---

Is it likely to be implemented? Incidentally I had taken dxf out put of CNC mill and following was the view ![image](https://forum.grid.space/uploads/default/original/2X/4/4e34d2273567dedd7dda5e4afaba325a76d9a81f.png) BTW I am unable to open dxf out put of laser cutting layout. I tried to online convert ‘workspace kmx’ file but no luck. Thanks for your quick response ---

cnc laser output is just gcode with laser on/off commands. can you point me to the 3D DXF spec? [Next page](https://forum.grid.space/t/aligning-laser-cut-slices/476.md?page=2)
