First run: if Windows shows “Windows protected your PC”, click More info → Run anyway. (It appears because this independent program is not code-signed.)
- Modeling — primitives and splines, Modify Poly / Modify Spline editing (Extrude, Inset, Bevel, Chamfer, Bridge…), modifier stack (Multi Select, Projection Spline, Pattern surface tiling (tri · quad · hex), Shell, Noise…), Boolean, Mirror, SMART Utils ▸ Drop Surface
- Copy — Shift+drag, then set a count: fill between original and copy / more at the same spacing
- Materials — Material Editor (M): PBR presets (matte · glossy · metal · glass · light), measured metal types, transmission, Roughness / Bump / Normal / Opacity maps, rendered previews, Random mapping, Color correct
- Mapping modifier — Box · Box Blur (soft seams) · Plane (Bend · Lattice) · Cylinder · Sphere · Spline
- GI Render (F9) — GPU path tracing: soft shadows, bounced light, reflections, refraction · Lights: Rect · Disk · Sphere · Spot with IES
- Cameras — Interior / Exterior / Product presets, 2-point perspective (vertical correction), Safe Frame ratios
- Animation — timeline, ● REC auto key, keys for move · rotate · scale · parameters · cameras, box-select / move / copy keys, RAM preview
- Import · Export — pick a format in File ▸ Import… / Export…: GLB (with animation) · FBX · OBJ · STL · PLY, video (MP4/WebM) · PNG sequence
- Auto Dim · Drawing — CAD-style dimensions on 3D objects (⚡ automatic, editable, PNG / PDF), drawing sheet with aligned orthographic views (KS 3rd angle · 1st angle), hidden lines, centre lines, an automatic isometric view and dimension snapping
- AI Render 1.3 (nodes) — connect view capture · GI render · loaded images · references (material · mood · object · person) · prompt · image / video generators on a node canvas; results side by side with A / B compare; the timeline ◉ Capture records your view moves as a video source
- AI Render — images and videos in one window
- Google Gemini (image) · Google Veo (video)
- Higgsfield API (key) · Higgsfield Login (plan credits, exe only) — model lists load automatically
- AI video from the animation capture (first / last frame + reference clip), before/after compare, viewport overlay
- In the program: Help ▸ Feature guide (with pictures) · hotkey list F1
- Separately: docs/SMART3D_Help_EN.html (download and open in a browser)
- exe: Windows 10 / 11 (64-bit)
- HTML: current Chrome or Edge (WebGL 2)
- AI features need an internet connection and your own account / API key for each service.
- API keys and login tokens are stored only on your PC and are never sent to the SMART 3D developer.
- Generation costs (credits) and terms of use are those of each service (Google, Higgsfield).
- A Higgsfield API key (open.higgsfield.ai) and a Higgsfield account login (higgsfield.ai) are different services. Account login works in the exe only.

I built SMART 3D as a personal project for my own 3D modeling and AI rendering work, together with Claude (Anthropic), an AI coding assistant. I did the planning and testing, and the code was written through conversations with Claude. SMART 3D is an independent program and is not affiliated with Anthropic.
