Tool Guide

Load a 3D model in STL, OBJ, 3MF, GLB, GLTF, or FBX format. Drag and drop onto the viewport or click Open in the Import panel. Maximum file size is 150 MB for cloud services (local repair has no limit).

After loading, the Import panel displays file name, format, size, triangle count, and bounding box dimensions (X/Y/Z). A service compatibility table shows whether the file fits within size limits for Local Repair (any size), Cloud Repair (150 MB), AI Tools (150 MB), and Quote Upload (150 MB).

Switch dimensions between millimeters (mm), centimeters (cm), and inches (in). Affects all dimension readouts throughout the app including bounding boxes, cut plane positions, and export dimensions.

Scans the mesh for topology issues: open edges, non-manifold geometry, inverted normals, sliver triangles, and holes. Reports vertex count, triangle count, surface area, volume, and a four-category quality score (Topology, Watertight, Normals, Geometry) with an overall percentage.

Sends mesh stats to Gemini AI for a classification report. Returns mesh type (thin shell, solid body, multi-body, surface patch), recommended repair strategy, confidence score, and plain-English reasoning about what is wrong and what to do next.

Visualizes mesh defects directly on the model with color-coded edge and face highlights. Open edges appear in red, non-manifold edges in orange, sliver triangles in magenta, and inverted normals in cyan. Each overlay type can be toggled independently, and counts are shown for each category.

Identifies disconnected shells (separate connected components) in the mesh. Reports total shell count, largest shell triangle count, and lists tiny shells (less than 1% of total). Tiny shells can be removed in one click.

After analysis, if issues are detected, the panel recommends a repair path. Minor issues (few open edges) get a Basic Repair recommendation. Severe damage gets a Deep Repair recommendation. One click takes you to the correct tool.

Runs all local repair steps in one pass: removes degenerate triangles, removes duplicate faces, fixes inconsistent winding, corrects inverted normals, welds nearby vertices, and fills small holes. Shows a detailed report of what was fixed and whether the mesh is now watertight.

Recomputes all face normals using flood-fill propagation to ensure consistent outward orientation across the entire mesh.

Inverts all face normals on the mesh. Unlike the Edit panel version, this affects every face.

Welds vertices that are very close together, closing tiny gaps caused by floating-point precision issues or bad exports.

Removes small disconnected components (islands) that are not part of the main mesh body.

Performs a boolean union of the mesh with itself using the Manifold library. Resolves self-intersections and overlapping geometry, producing a clean outer shell.

Adds wall thickness to a thin surface mesh, turning a single-sided shell into a printable solid. Adjustable thickness from 0.5 to 20 mm.

Toggle between the repaired mesh and the original geometry to visually compare what changed during repair.

Sends the mesh to a cloud worker running PyMeshLab, Open3D, and trimesh for a 13-stage pipeline: triangle soup detection, adaptive welding, manifold repair, hole filling with smart classification, internal face removal, debris removal, thin wall detection, self-intersection removal, feature edge preservation, and more. Two modes available: Auto Repair (auto-detects damage level) and Simplify & Rebuild (collapse, subdivide, smooth).

Enables direct triangle manipulation. When active, clicking on the mesh selects individual triangles. Shift+click adds to the selection. Six selection modes are available: Click (single triangle), Lasso (freehand draw), Box (rectangular region), By Normal (all faces within an angle threshold of the clicked face), Connected (flood-fill to connected geometry), and Sharp Edges (faces along edges exceeding an angle threshold).

Bulk selection operations: Select All, Invert Selection, Grow Selection (expand by one ring of adjacent triangles), Shrink Selection (contract by one ring), Select Connected (flood-fill from current selection), and Select By Normal (extend selection to faces with similar normals).

Removes selected triangles from the mesh. Creates open holes that can then be filled with the Repair or Fill Hole tools.

Inverts the normal direction of only the selected faces, leaving the rest of the mesh unchanged.

Splits each selected triangle into four smaller triangles by adding midpoint vertices on each edge. Increases mesh density in the selected region.

Reduces the triangle count of the selected region to a target percentage using quadric edge collapse. Preserves overall shape while removing unnecessary detail.

Applies Laplacian smoothing to selected faces. Reduces surface noise and jagged edges. Configurable iteration count and strength.

Pushes selected faces outward along their normals by a configurable distance, creating new side walls. Effectively adds material to the selected region.

Connects two open edge loops with new faces, creating a tube-like bridge between them. Select faces adjacent to both open boundaries, then bridge.

Fills an open boundary adjacent to the selected triangles with new faces. More targeted than the global Fill Holes repair tool.

Detaches the selected triangles into a new, independent mesh part. The original mesh loses those faces.

Enables vertex dragging on selected triangles. Click and drag individual vertices to reshape the mesh geometry.

Merges nearby vertices within the selected region that fall within a configurable tolerance distance.

Converts the mesh to a voxel grid using parity fill and flood fill, then extracts a new surface via marching cubes. Always produces a watertight, manifold result. Adjustable voxel resolution, sharp edge threshold, and surface mode (Auto, Organic, Mechanical).

Surface rasterization with dilation. Wraps the mesh in a new surface while preserving openings. Good for meshes that should remain open (not solid).

Treats mesh vertices as a point cloud and reconstructs the surface using MLS/SDF reconstruction. Best for thin shells and car bodies where voxel methods produce artifacts.

Applied after reconstruction. Taubin smoothing removes voxelization stairstepping without shrinking the mesh. Optional simplification reduces triangle count by ~20% using quadric edge collapse.

Mirrors the mesh across a chosen axis (X, Y, or Z) to reconstruct missing geometry from an intact side. Useful for symmetric objects where one half is damaged.

Generates multiple reconstruction variants with different settings for A/B comparison. Presets: Fine Detail (60% resolution), Fast Preview (180% resolution), Alt. Mode (switches solid/shell/point cloud), and Smooth (extra smoothing).

Rebuilds mesh topology using AI to create clean, uniform polygons. Choose triangle or quad output, set a target polycount (100 -- 300K), and configure feature preservation options: sharp edge detection, adaptive density (higher density in detailed areas), symmetry detection, and feature sensitivity (0 = smooth, 1 = preserve all detail). Output in STL, OBJ, GLB, or FBX.

Generates UV-mapped PBR textures from a text description. Describe the material you want (e.g., 'brushed steel with red anodized accents') and the AI creates color, normal, roughness, and metallic maps. Configurable resolution (512 -- 4K), style presets (realistic, stylized, hand-painted, cartoon, sci-fi), guidance scale, and seed.

Generates a new 3D model from a text prompt. Two-stage workflow: Preview generates the mesh shape quickly, then Refine adds full textures and detail. Configurable output topology (triangles/quads) and target polycount.

Upload a single photo (JPG/PNG, max 20 MB) and generate a 3D model from it.

Upload 1 -- 4 photos of the same object from different angles for a more accurate 3D reconstruction than single-image generation.

Lay Flat automatically rotates the model to rest on its largest face. Rotate 90 buttons let you quickly rotate on X, Y, or Z axes. All rotations bake into the geometry.

Reflects the model across a chosen axis (X, Y, or Z). The geometry is mirrored in place.

Analyzes overhangs, wall thickness, and watertightness. Produces a Print Score (0 -- 100%) with sub-scores for Overhang, Thickness, and Watertight. Lists specific warnings about problem areas. Configurable overhang threshold angle.

Highlights overhang faces on the model with a color gradient. Shows count, percentage of mesh, and maximum overhang angle.

Creates a hollow shell from a solid mesh to save material. Adjustable wall thickness (0.5 -- 10 mm). Reports original volume, hollow volume, and percentage of material saved. Mesh must be watertight.

Adds drainage holes to the bottom of a hollowed mesh for resin or powder removal. Configurable hole radius (1 -- 10 mm). Only available after hollowing.

Generates a preview of support columns for overhang areas. Shows column count and estimated support volume. Requires running printability analysis first. Configurable column radius.

Per-axis scale sliders (0.1x -- 10x) with optional uniform scaling lock. Per-axis rotation sliders (-180 to +180 degrees). Reset button restores original transforms.

The default split method. Tries Manifold first for the cleanest possible caps. If the mesh is not watertight or Manifold fails, falls back to Ear Clip automatically.

Uses the Manifold library's splitByPlane operation. Produces the cleanest, most geometrically correct caps. Requires a watertight, manifold mesh to work.

Clips the mesh against the cut plane and generates caps using ear-clipping triangulation. Handles concave cross-sections well. Works on non-watertight meshes.

Uses centroid fan triangulation for aggressive cap fill. Connects all boundary vertices to a central point. May produce non-planar triangles on complex cross-sections.

Clips the mesh at the cut plane but does not generate any cap faces. The resulting parts have open edges along the cut line.

When enabled, skips solid repair steps before splitting and prevents hollow artifacts. Designed for shell and panel meshes.

Add cut planes on X (red), Y (green), or Z (blue) axes. Each plane has a position slider (5% -- 95% of the bounding box), an enable/disable toggle, and a snap-to-center button. Multiple planes can be added for multi-cut splits. Planes are visualized in the viewport as translucent discs.

Adds alignment features to split faces so parts snap together during assembly. Four types: None, Cylinder Peg (post and socket), Dovetail (interlocking wedge), and Dowel Pins (multiple small pins). Configurable size and hollow option.

After splitting, spread parts apart to inspect cut quality and cap faces. Slider controls the explode distance (0 -- 100%). Part number labels can be toggled on/off.

After splitting, click any part in the parts list to select it, then click Repair Part to run topology repair on that individual part. Fixes any issues introduced by the split.

Exports all split parts as individual files in your chosen format (STL, OBJ, or GLB) bundled in a ZIP archive. Includes a JSON manifest with part dimensions and metadata, plus an HTML assembly guide with 6-view spatial layout diagrams showing part numbers, zones, colors, dimensions, and assembly order.

Download any single part in your chosen format. Each part card shows triangle count and bounding box dimensions.

Sends all parts to the quote system for print cost estimation.

Runs topology repair on every split part in batch. Fixes any issues introduced by the split process across all parts at once.

Calculates estimated print weight for each part and total, based on part volume and selected material density. Supports PLA, PETG, ABS, ASA, TPU, Nylon, Resin, and Carbon Fiber materials.

Choose between STL (universal, best for 3D printing), OBJ (with normals, good for rendering), and GLB (compact binary, supports textures and PBR materials).

Renders the mesh as a wireframe, showing only edges. Useful for inspecting topology density and edge flow without solid surfaces blocking the view.

Makes the mesh semi-transparent (28% opacity). Allows you to see through the surface to internal geometry, cut planes, or the back side of the model.

Shows color-coded defect edges and faces directly on the mesh. Red = open edges, orange = non-manifold edges, magenta = sliver triangles, cyan = inverted normals. Controlled from the Analyze panel.

Highlights faces that exceed the configured overhang threshold angle with a color gradient. Controlled from the Prepare panel after running printability analysis.

Displays generated support columns as semi-transparent cylinders beneath overhang regions. Controlled from the Prepare panel.

After splitting, each part is rendered in a distinct color. Cut plane discs are shown in the viewport with their axis color (red/green/blue). Parts can be selected by clicking.

After splitting, toggle numbered labels on each part. Use the explode slider to spread parts apart for inspection. Both controlled from the Split panel.

Real-time log of all operations: repair steps, reconstruction progress, cloud job status, AI task stages, split progress, and error messages. Each entry is timestamped and color-coded by status (running = blue, done = green, error = red).

Interactive command line for power users. Type commands to run repair, split, export, and analysis operations without using the GUI panels. Tab completion and command help available.

Lists all current mesh issues detected by analysis: open edges, non-manifold edges, inverted normals, and other defects. Updated after each analysis pass.

Chat interface for the mesh repair AI agent. Ask questions about your mesh, get repair recommendations, or request the agent to run specific operations.

When a repair or split operation fails, the error is logged in the Problems tab with context. Bug reports can be submitted directly from the Repair panel to report issues with the repair pipeline.

Restores the previous or next mesh state. Supports up to 20 undo levels. Ctrl+Z for undo. Each state stores the full mesh geometry.

Shows all operations performed on the mesh with timestamps and operation names. Click any entry to jump directly to that mesh state, skipping intermediate steps.
