Help Creating Stencils From Fusion Electronics

I am trying to workout a simple workflow to take my PCB designs in Fusion Electronics (I know) to laser cut stencils. Following some people struggles on fusions forums I have found that selecting just the paste layer I want and using their built in DXF ulp script is the fastest way to a dimentionally accurate dxf. Opening this DXF in auto-cad and online viewers everything looks good. But I can’t seem to get it to show up in LB. I have tried converting to SVG aswell with no luck.

So far so similar to 10s of other forum posts. I was going to just keep trying fixes listed in those topics but i tried drawing a circle around my test stencil in auto cad and that shows up. So now I’m lost I feel like I’m missing something basic. Any help would be much appreciated

I tried it in Lightburn and only got a circle.

I opened it in FreeCAD and got this

Don’t know what to tell you at this point, other than a different format, such as SVG?

This is how it looks in InkScape:

CorelDRAW! 2018:

Affinity Designer:

DraftSight:

LibreCAD:

So, some apps are better than others at rendering your file! I’m guessing that LibreCAD and Affinity are the correct renderings? If you can confirm that and let us know what other applications you have access to then we might be able to give some guidance using a specific app for further processing. You might also be able to export from Fusion as PDF (from the drawing workspace) and import that into LB but I’d hazard a guess that this might require further processing as well.

How’s this?

That looks better… I have no traces…?

It’s got some kind of bump on the right side.

Yes, all of the smaller circles are actually defined as points in the DXF file. I’ve not been through the DXF in any detail manually but I’m assuming that there must be a lineweight setting (or similar) that defines the ‘diameter’ of those points. One of these points overlaps the large ring, creating that bump.

Hello, Thank you guys for your replies, It seems that fusion doesn’t have a simple way of exporting just the layer I want to DXF or SVG cleanly. I have had similar issues with the file opening completly different in different viewers. Most importantly it opens to just a circle in Lighburn. My solution was to export my baord file to KiCad and use its SVG ploting features. Not Ideal but it worked.

Thanks all for the help/intrest, and if anyone knows some fusion wizardry it would be much apreciated.

Draftsight and Corel Draw were the closest. and with a couple of edits your file did the trick thanks!
