Installing

Windows (x64 / ARM64):

winget install Volko61.Merge360
winget upgrade Volko61.Merge360   # update

Linux (x86_64 / aarch64): installs to ~/.local/bin (or /usr/local/bin as root), verifies the SHA-256 checksum and adds a desktop entry.

curl -fsSL https://raw.githubusercontent.com/Volko61/Merge360-Vibecoded-Inspired-Fusion360/main/install.sh | sh
# or
wget -qO- https://raw.githubusercontent.com/Volko61/Merge360-Vibecoded-Inspired-Fusion360/main/install.sh | sh

Updating: run merge360 --update (uses winget on Windows, the install script on Linux), or re-run the command above. MERGE360_VERSION=0.3.0 pins a version and MERGE360_UNINSTALL=1 removes it. Archives are also on the releases page.

Running

cargo run --release -p merge360            # empty design
cargo run --release -p merge360 -- part.m360   # open a design

Help ▸ Open Sample Design loads a demo part.

Linux needs a Vulkan (or OpenGL) driver. Under WSL without GPU drivers Merge360 runs on Mesa's CPU rasterizer (llvmpipe): it then disables MSAA and caps the 3D render resolution so that fullscreen stays interactive. Set WGPU_BACKEND=gl or vulkan to force a backend.

Working features

Sketch (on origin planes, construction planes or planar faces): line, 2-point / center rectangle, circle, 3-point arc, polygon, point; parametric: sketch dimensions (lengths, distances, diameters) and constraints (horizontal/vertical, coincident, parallel, perpendicular, equal, tangent, concentric, fix) solved by a built-in constraint solver; drag points with the Select tool; automatic H/V constraints; midpoint, collinear and symmetry constraints; center-to-center slot, fit-point spline, ellipse; project body edges/faces, extend, break; trim, offset, sketch fillet; mirror (linked by symmetry constraints), circular / rectangular pattern, move, scale; sketch text (font outlines, extrudable).
Create: Extrude of sketch profiles or planar body faces (push/pull; new body / join / cut / intersect, one side or symmetric, taper angle, profiles with holes), Revolve (around X/Y/Z or a sketch line), Sweep and Pipe (along connected lines/arcs, hollow pipes), Loft, Hole (simple / counterbore / countersink, distance or through all, multiple points), Box, Cylinder, Sphere, Torus, Coil (circular / square / triangular sections, tapered), Rectangular, Circular & Path Pattern, Mirror — all with live preview and drag manipulators.
Modify: Fillet and Chamfer (straight edges between planar faces, incl. face loops), Shell (prismatic bodies, open faces), Draft (side faces of prismatic bodies), Thread (cosmetic, ISO metric sizes auto-detected from the face), Combine (join / cut / intersect), Split Body, Scale, Move/Copy, Press Pull (edges → fillet, profiles → extrude), Delete, Appearance, Physical Material (19 materials; mass and center of mass use their densities), Change Parameters, Compute All.
Surface: Extrude and Revolve of open or closed sketch curves (lines, arcs, splines), Patch, Stitch (closed results become solids), Delete Face, Reverse Normal, Move.
Construct: Offset Plane, Plane at Angle, Midplane, Plane Through Three Points. Sketches, holes and planes work on faces of any orientation.
Assemble: Components (new / activate / visibility), Joints (rigid, revolute, slider with live motion value).
Parameters: user parameters and expressions (width * 2 + 5 mm) for any feature value.
Insert: Insert Mesh (STL, binary/ASCII) as polyhedral bodies that take part in booleans; Insert DXF (lines, arcs, circles, polylines with bulges, splines, ellipses) into a new sketch.
Inspect: Measure (edge length, face area, body volume, minimum distance), Interference, Section Analysis (with section caps), Center of Mass, Properties.
DRAWING workspace: A3 sheet with title block, Front / Top / Right / Isometric views in third-angle layout with hidden-line removal (dashed), true silhouettes of curved faces, automatic standard scale, overall dimensions, SVG export.
MANUFACTURE workspace: milling setups (stock around the model, WCS on the stock top), Face, 2D Contour (inside/outside), 2D Pocket (with islands), Drill (peck) operations from sketch geometry, tool/feeds/stepdown settings, toolpath display, simulation and G-code post processing (.nc, generic Fanuc/GRBL dialect).
SIMULATION workspace: linear static stress study — fixed faces, face forces (normal or along an axis), voxel finite-element solver (8-node hexahedra, conjugate gradient) using the body's material (E, ν, yield), von Mises stress / displacement / safety-factor color maps on the deformed shape (validated against beam theory).
ANIMATION workspace: storyboard of timed body moves/rotations, Auto Explode, playback and video export (PNG frames at 24 fps).
RENDER workspace: presentation view (environments, soft ground shadow, optional edges) and high-resolution image rendering to PNG (HD to 4K).
Preferences (user menu ▸ Preferences, saved in ~/.config/merge360/preferences.ron): language (English, Français, Deutsch, Español — extra or corrected strings can be added in ~/.config/merge360/lang/.txt), keyboard shortcut presets (Fusion 360, Blender, SolidWorks) with per-action rebinding, mouse navigation presets (Fusion 360, Blender, SolidWorks, Inventor, Tinkercad) with zoom/orbit/pan speed and reversed zoom, interface scale, default units, grid/snap defaults, ViewCube, frame-rate display and auto-saved recovery copies.
Files: native .m360 (RON, full parametric history), STL import, STL and STEP export.
Fully parametric: every feature is re-editable from the timeline (double-click), roll back with the marker, suppress features; undo/redo for everything.

Tools that are not implemented yet (modeled threads, the Generative Design workspace, …) are present in the UI and report “not available yet”. Kernel limitations (truck): fillets meeting three at a corner, shells of non-prismatic bodies and booleans of exactly coplanar faces may fail; such features turn red in the timeline with an explanation.
