True-shape nesting for plasma, laser and router parts that packs real outlines tight and exports DXF or SVG for CAD/CAM, with no install or subscription.

About

NestMaxx uses the No Fit Polygon method to find every position where a part sits against its neighbours without overlapping, so real outlines interlock instead of bounding boxes. Leftover sheet area can be cropped as a reusable offcut, and the layout can fill multiple sheets while flagging parts that did not fit. Parts can be imported from DXF or SVG with layer and unit selection, or drawn in the built-in 2D editor, and rotation can be locked to a grain axis for brushed or rolled stock.

Key Features

Nests parts by their real outline using the No Fit Polygon method
Imports DXF and SVG files, including splines, ellipses and arcs
Exports the nested layout as DXF (R12) or SVG for CAD/CAM
Crops reusable offcuts from leftover sheet space
Locks grain direction or sets fixed rotation angles per part
Provides over 40 parametric shapes and a built-in 2D CAD editor

Use Cases

Packing brackets and gussets tightly onto a plate before cutting on a plasma, laser or waterjet
Fitting cabinet parts and cut lists onto a sheet of ply, MDF or melamine for a CNC router or panel saw
Laying out intricate laser-cut parts in plywood, acrylic, leather or fabric to minimise waste

From the founder

Who it's for

“Small fabrication shops, makers and engineers who cut parts from sheet on a laser, plasma or CNC router and want tighter nests and less scrap without paying for expensive CAM software.”

Why I built it

“I made NestMaxx because true-shape nesting is usually locked inside expensive CAM software, and the free tools I tried were slow or hard to trust with real dimensions. It runs entirely online on your own device, free, with no account.”

— Nestmaxx Software, founder of NestMaxx

Who it is for

Sheet metal and plasma cutting shops
Woodworkers running CNC router or panel saw jobs
Laser cutting workshops working in plywood, acrylic, leather or fabric

Pricing

NestMaxx is free to use. See the website for details.

FAQ

What file formats can I import?

DXF and SVG. Splines, ellipses and arcs come in as true curves, and you can choose which DXF layers to include and set the units per file.

What can I export?

The nested layout as a DXF (R12) or SVG, ready for another CAD/CAM package.

Can I control rotation and grain direction?

Yes. Let parts rotate freely, lock the grain axis so brushed or rolled stock runs one way, or set fixed angles either per part or for the whole sheet.

Can I draw my own parts?

Yes. Pick from over 40 parametric shapes, or draw a part in the built-in 2D editor with lines, arcs, fillets and trims. It checks the outline is cut-ready before you nest.

Does it nest across multiple sheets?

Yes. It fills as many sheets as you allow, flags which parts did not fit, and can crop a reusable offcut from the leftover.
