Add-in for Autodesk Fusion · Windows
Mesh++ adds its own tab to Fusion with seven commands: turn STL scans and CAD exports into real B-Rep solids, then repair, sketch on, split and pack meshes — right in your design and timeline.
Repair
Convert
Sketch
Create
ModifyChoose the conversion that matches the shape. Both create native Fusion geometry in your timeline, and both tell you how close the result is to the mesh.
For 3D scans, sculpts and freeform shapes. Mesh++ remeshes the triangles into clean quads, then builds a T-Spline body that Fusion turns into a solid or a surface.
For parts that came from CAD. Mesh++ recognises the design behind the triangles and rebuilds it as native Fusion features, with real radii, axes and tangencies.
Turn a structured-light or photogrammetry scan into a smooth solid you can measure, cut and fillet.
OrganicRebuild a part from its STL with real planes, holes and fillets, then change it like any Fusion design.
MechanicalRepair meshes, split them into printable pieces and fill a build plate or powder bed in one click.
Repair · Split · PackBring sculpts from ZBrush or Blender into Fusion as T-Spline bodies with the detail you choose.
OrganicBeyond conversion, Mesh++ lets you prepare, draw on, cut and pack meshes without leaving Fusion. Every command is undoable and keeps your original mesh.
Convert › OrganicScans, sculpts and freeform shapes become smooth T-Spline bodies, converted to a solid or a surface in your timeline.
Convert › MechanicalParts that came from CAD are rebuilt with real planes, cylinders, holes, pockets and fillets — as parametric features or one clean closed solid.
RepairClose holes and fix flipped or non-manifold triangles with the Windows 3D printing repair, with a report of what is left.
Sketch › Sketch on MeshDraw splines and polylines that follow the surface, or let Detect Edges add sharp edges and face boundaries as exact lines, arcs and circles.
Create › Extrude Spline to MeshSweep a curve into a ribbon, rectangle or ellipse, straight or normal to the mesh, with Fusion's own distance and angle handles.
Modify › Split MeshCut a mesh with other meshes, the way Split Body works. Exact arithmetic gives pieces that fit together, closed or open as you choose.
Modify › Pack MeshesFill the build volume of your printer with meshes, solids and surfaces, as low or as compact as possible, with guaranteed spacing.
Three steps, without leaving Fusion and without exporting anything.
Bring an STL, OBJ or 3MF into Fusion with Insert Mesh, as you do today. Scans, sculpts and CAD exports all work.
Open the Mesh++ tab and choose Organic or Mechanical. Keep the defaults or set your tolerance and quad count.
The solid lands in your timeline as native Fusion geometry. Fillet it, shell it, cut it — the source mesh stays in the browser.
Mesh++ measures every body it creates against your mesh, in both directions, and tells you when a result is out of tolerance instead of hiding it.
Sampled distances from the mesh to the result and back, reported with every conversion.
A result outside your tolerance is never accepted silently: Mesh++ asks before changing a setting.
Everything runs on your computer with the bundled engine. Your models are never uploaded.
Pay once and keep Mesh++ forever. No subscription, no renewal, every command included.

All included in every licence. Rebuilding a part from an STL by hand takes hours; Mesh++ turns a 236,638-triangle Benchy into one closed 322-face solid in about a minute.
For makers, hobby projects, learning and personal prints. That is about 7 € per command.
For businesses, freelancers and any paid work.
Your Polyprod Pro licence works with Mesh++ as it is. Sign in to see your licences.
Our standalone 3D printing software for SLS and Multijet is still available, with a free Standard edition.
Download Mesh++ from your account right after payment. Prices in euros, VAT included, secure payment by Stripe. Several licences? Contact us.
Insert the STL with Insert Mesh, open the Mesh++ tab and run Mesh to Brep: Organic for scans and sculpts (a smooth T-Spline solid), Mechanical for parts designed in CAD (planes, cylinders, holes and fillets as native features). The solid lands in your timeline and the mesh is kept.
Autodesk Fusion (formerly Fusion 360) on Windows 10 or 11, 64-bit. The conversion engine is bundled with the add-in: there is nothing else to install. The beta clean CAD reconstruction also uses a local Python with NumPy and SciPy. Mesh++ is not available on macOS.
Any mesh body in Fusion: STL, OBJ or 3MF files inserted with Insert Mesh, from 3D scanners, photogrammetry, sculpting tools or CAD exports. Closed meshes give solids; open meshes give surfaces with Organic.
Use Organic for scans, sculpts and freeform shapes: it gives a smooth T-Spline body with a quad count you choose. Use Mechanical for parts that were designed in CAD: it rebuilds planes, cylinders, holes, pockets and fillets as native Fusion features.
Feature recognition covers the common CAD families: extrusions, revolutions, holes and counterbores, pockets and constant fillets. The clean CAD reconstruction handles other shapes and is still in beta: it always reports the deviation, and your mesh stays visible when a result is outside your tolerance.
Right after payment, sign in to your account: the Mesh++ download and the installation steps are there. Unzip the folder, add it in Fusion from Utilities > Scripts and Add-Ins, and click Run. Your downloads stay available in your account.
A licence is used on one computer at a time. Sign out of Mesh++ to move it to another computer, or release it from your account if the first one is no longer available. You can change computer once a day; buy one licence per simultaneous user.
Mesh++ checks your licence online when Fusion starts, which Fusion does anyway. If your computer is offline, Mesh++ keeps working for up to 6 days after the last successful check.
No. You pay once and keep your licence for life: 49 € for personal use, 199 € for commercial use.
The Personal licence is for non-commercial use: hobby projects, learning and personal prints. As soon as Mesh++ is used for a business or for paid work, choose the Commercial licence.
Yes. A Polyprod Pro licence also unlocks Mesh++.
No. All the computation runs on your computer with the bundled engine. Your models are never uploaded.
