Who Is This For?

Architects, interior designers, visualizers, and educators.
AutoCAD/3ds Max/Revit users who want faster concept modeling.
Anyone needing sketch/image → 3D starting points for further refinement.

Learning Outcomes

Generate 3D meshes from single sketches or images.
Capture real objects with photogrammetry and clean the output.
Export and import models into AutoCAD, 3ds Max, and Revit reliably.
Retopology, smoothing, and CAD/BIM-friendly cleanup best practices.

Meshy.ai – Sketch/Image → 3D (Suggested: 6 hours)

Meshy converts a single image or sketch into a watertight mesh, with controls for topology and texturing.

Inputs & prompts for furniture/façade elements.
Remeshing & polygon count control for downstream use.
Export: OBJ, FBX, GLTF → import to AutoCAD/3ds Max/Revit.
Exercise: Sketch a table or mashrabiya tile → generate → retopo in 3ds Max.

Scan2CAD – Raster/Image → DXF/DWG Polylines (Suggested: 3 hours)

Scan2CAD converts scanned drawings, logos, and high-contrast patterns (e.g., mashrabiya/arabesque tiles) into clean DXF/DWG polylines for AutoCAD. Ideal when you need editable linework rather than a mesh.

Vectorization modes: Outline, Centerline, and OCR for text.
Cleanup controls: threshold, despeckle, gap fill, arc/line fitting, and polyline simplification to reduce nodes.
Export: DXF/DWG/SVG; layer and color mapping for CAD standards.
Use cases: ornamental grills, façade motifs, scanned details, furniture contours for precise CAD redraw.

Mini-Workflow

Prepare a high-contrast black-on-white image (PNG/JPG). Crop to the tile/shape you need.
Import to Scan2CAD → choose Vectorize → start with Outline for silhouettes or Centerline for strokes.
Tune Threshold, enable Reduce Speckle, and Shape Fitting (lines/arcs) → Preview.
Export as DXF → open in AutoCAD → run OVERKILL and PEDIT > JOIN → scale and array as blocks.

Exercise

Convert an oriental window pattern into a single clean polyline tile, save as a block, and create a rectangular and polar array. Deliver a DWG with layers (Pattern, Frame) and a plotted PDF.

Tip: For filled shapes, choose Outline. For line drawings, try Centerline. If curves look faceted, increase arc fitting or smooth later with PEDIT > Spline.

Luma AI – Single-Image/Video to 3D (Suggested: 4 hours)

Luma creates 3D from a single image or short video capture (NeRF/GS). Great for quick concept assets and product forms.

Capture tips: lighting, parallax, backgrounds.
Export meshes & textures; limitations vs CAD solids.
Exercise: Capture a chair with a phone → export → render in 3ds Max.

Kaedim (Service Pipeline) (Suggested: 3 hours)

Kaedim provides a managed service: you supply refs or concept art, they return a cleaned mesh suitable for DCC apps.

When to use a service vs DIY generation.
Deliverables, license, and revision loops.
Exercise: Submit a complex prop; compare with Meshy output.

Photogrammetry (Kiri / Polycam) (Suggested: 6 hours)

For real objects and site artifacts, photogrammetry turns multiple photos into accurate 3D meshes.

Shooting workflow (turntable vs walk-around).
Reconstruction settings, decimation, texture bakes.
Export to OBJ/FBX → retopo in 3ds Max → Revit family wrapping.
Exercise: Scan a decor element → create a clean, lightweight asset.

AutoCAD / 3ds Max / Revit Integration (Suggested: 5 hours)

AutoCAD: Import OBJ/FBX → scale → PEDIT/OVERKILL cleanup → arrays/blocks for patterns.
3ds Max: Retopology, smoothing groups, UV unwrap → materials (V-Ray/Corona) → render.
Revit: Import to Mass/Furniture family → set categories & materials → replace with native forms where precision is needed.
Deliverable templates: scene units, naming, LOD, and file size targets.

Quality & Ethics

Attribution & licensing for reference images.
Client approvals: clearly mark AI-assisted concept vs. CD-grade geometry.
Performance budget: polygon limits for BIM and real-time apps.

Final Project

Create a themed interior prop set (e.g., oriental window + table + lamp):

One asset from a sketch (Meshy), one from a single photo/video (Luma), one via photogrammetry.
Retopo and import into 3ds Max for texturing and rendering.
Wrap a hero asset as a Revit family and place it in a sample room.
