Quick3DModeling User Guide
Quick3DModeling turns simple parametric shapes into editable, print-aware projects without hiding the solid-and-hole structure.
Getting Started
- Create a project from the Library or choose a Template.
- Add a primitive or Print Helper from Shapes.
- Select it in the viewport or Outliner and enter exact values in Inspector.
- Use workplanes, snap, measurement, alignment, and Solid/Hole roles to assemble the model.
- Run Print Check, resolve blocking findings, then export 3MF, STL, or OBJ.
Tip: Place a solid base before Hole objects in the same Boolean group.
Interface Overview
| Area | Purpose |
|---|---|
| Project Library | Editable .q3dm projects, folders, favorites, tags, search, versions, trash, and duplicate. |
| Viewport | Select, orbit, pan, zoom, place, and inspect model geometry. |
| Shapes | Parametric primitives, Hole helpers, Print Helpers, and text. |
| Outliner | The ordered CSG tree, groups, visibility, locks, and object roles. |
| Inspector | Dimensions, transforms, material color, clearance, workplane, and print-related values. |
From Editable CSG to Print Check
Mesh export stays unavailable while the current Print Check has blocking errors, so warnings remain visible before a slicer receives the model.
- Parametric primitives: Build with boxes, cylinders, spheres, cones, tubes, text, and other dimension-driven shapes.
- Solid and Hole CSG: Add and subtract material with an explicit, non-destructive Boolean tree.
- Templates and helpers: Start with stands, hooks, plates, clips, brackets, holes, nut traps, spacers, and cable channels.
- Exact inspection: Edit size, position, rotation, color, clearance, fillet, chamfer, alignment, and workplanes.
- Print Check: Review mesh validity, bed fit, build-plate position, walls, details, and export scope.
- Project and mesh export: Keep editable .q3dm files and create 3MF, STL, or OBJ for downstream tools.
Note: Print Check is an editing aid, not a guarantee of mechanical strength, printer safety, dimensional tolerance, or fitness for a particular use.
Settings
Open Settings to review the following app-specific controls:
- Theme, viewport, grid, snap, and measurement preferences
- Keyboard shortcut customization
- Autosave, version snapshots, and external-change behavior
- Print bed and export defaults
Trial, Free, and Pro use the same functional feature set. Pro removes mobile ads and the daily desktop support reminder.
Keyboard Shortcuts
On Apple platforms, use Command where the app maps a displayed Ctrl shortcut to the platform primary modifier. The in-app shortcut page remains authoritative.
| Shortcut | Action |
|---|---|
| Cmd/Ctrl + N | Create a new model |
| Cmd/Ctrl + Z | Undo |
| Cmd/Ctrl + Y | Redo |
| Cmd/Ctrl + D | Duplicate selection |
| Delete | Delete selection |
| Cmd/Ctrl + A | Select all shapes |
| Arrow keys | Nudge selection |
| R | Rotate the active selection |
Tips & Tricks
Place a solid base before Hole objects in the same Boolean group.
Use clearance on screws, pins, cables, and moving joints instead of manually oversizing every hole.
Pin important measurements before changing the surrounding geometry.
Prefer 3MF when units and color matter; use STL for broad slicer compatibility.
Troubleshooting
| Problem | What to check |
|---|---|
| A Hole does not subtract | Confirm that it follows a solid base inside the same Boolean group. |
| Mesh export is disabled | Run Print Check and resolve every blocking error in the current report. |
| A model opens with a conflict | Compare the external edit and keep or reload the correct .q3dm version. |
| A part is off the build plate | Use Measure and Inspector to correct its Z position and bed bounds. |
Privacy
- Projects and geometry are processed locally.
- QuickLibrary accesses only locations you add.
- Editable .q3dm projects, version snapshots, and exports remain under your control.
- No account is required for core modeling.
Your responsibility: Do not create prohibited items or rely on the App as a substitute for engineering, material, or safety validation.
