Fusion 360 nesting: what is paywalled, and the workflow around it

You drew your parts in Fusion 360, you want them arranged on one sheet, and the Arrange command is missing or grayed out. That is licensing, not a bug. Here is what each license level actually includes, and the export-nest-import workflow that hobby users, including most Langmuir plasma owners, run instead.

Which Fusion 360 license includes what

Autodesk answers this directly in its knowledge base article on nesting in Fusion 360. Condensed:

Two things worth understanding before you spend money. Arrange is a layout command, not a true-shape nester: useful for spreading parts out, but it will not interlock irregular outlines to save material. And the Nesting & Fabrication Extension is a recurring cost on top of a subscription. For a business nesting steel every day it can be worth it. For a hobbyist cutting a few sheets a month, the workflow below does the same job for the price of a little clicking.

The workflow: DXF out, nest, CAM back in

The good news is that the free Personal Use license keeps the two ends of the pipeline you need: DXF export and CAM. Only the nesting step happens outside.

1. Export each part as DXF. Right-click the sketch in the browser tree and choose Save As DXF; for sheet metal parts, create the flat pattern first and export that. This local export uses your document units, typically millimetres. Exporting from the Fusion web hub instead writes centimetres and causes classic 10x size surprises, so export from the sketch.
2. Nest externally. Load the DXFs into your nesting tool, set the sheet to your real material size, set part quantities, and set the spacing for your process. Plasma needs room for lead-ins and pierces between parts; the nester does not know your lead-in lengths, so add that allowance to the spacing value yourself.
3. Bring the nested sheet into CAM. On Langmuir tables the usual chain is the nested DXF into SheetCAM for toolpaths and G-code, then FireControl to run the cut. Staying inside Fusion works too: insert the nested DXF into a new design and program it in the Manufacture workspace. Either way, kerf compensation and lead-ins are applied here, in CAM, not in the nesting step.
4. Check one dimension. After any DXF round trip, measure a known feature before cutting. Unit mismatches are the most common failure in this workflow and they cost a sheet of steel when they slip through.

The trade-off to be aware of: the nested DXF is flat geometry. It no longer updates when you edit the Fusion model, so nest when the parts are final, or expect to repeat the export.

If you want to stay inside Fusion: MapBoards Pro

There is a middle path. MapBoards Pro is a paid third-party add-in from the Autodesk App Store that arranges your components onto board-sized layouts inside the design itself. The layout stays in your Fusion file, so the Manufacture workspace references the same model and there is no DXF round trip at all. If your priority is never leaving Fusion and your parts suit its layout approach, it is the closest thing to the paid extension at hobby prices. It is still a layout tool inside Fusion's constraints rather than a dedicated true-shape nester, so for maximum material use on irregular parts the external route usually wins.

Where NestForge fits in this workflow

NestForge is built for exactly the middle step: it reads the DXFs Fusion exports (parsed locally in your browser, nothing uploaded), nests them true-shape on your sheet size, and exports a nested DXF per sheet that SheetCAM and Fusion both read. Arcs stay real ARC entities through the whole trip, so circles are still circles in CAM instead of polygon approximations. Layouts are deterministic and every one is checked by an independent exact-arithmetic validator before you see it. It is a one-time purchase rather than a subscription or extension, and the free tier (10 parts on 1 sheet, no time limit) is enough to test the full Fusion round trip on your own parts first.

The equally important honest half: NestForge produces no toolpaths and no G-code, and it does not know your lead-ins, pierces or kerf compensation. The way back into CAM is part of the workflow, not optional: nested DXF into SheetCAM or Fusion's Manufacture workspace, same as with any external nester. If you need nesting and toolpaths fused into one step, that is precisely what Autodesk's paid extension is for.
