Choose Polycam if you need to turn real-world objects or spaces into 3D models or floor plans — it excels at reality capture from photos, LiDAR, and drones. Choose Prompt2CAD if you want to generate parametric CAD models from text descriptions without touching a 3D scanner or CAD software. They serve different stages of the design workflow: capture vs. ideation.

Who should pick which

  • Architect needing floor plans of existing buildings
    Pick: Polycam

    Polycam generates automatic floor plans with measurements from LiDAR or photos, exports as DXF or PDF, and is used by AEC professionals.

  • Product designer iterating on a new enclosure
    Pick: Prompt2CAD

    Prompt2CAD lets you describe the enclosure in text, adjust dimensions conversationally, and export as STEP for manufacturing, without CAD skills.

  • Forensics team documenting a crash scene
    Pick: Polycam

    Polycam captures accurate point clouds and 3D models from photos or LiDAR quickly, exportable to LAS or PLY for analysis.

  • Maker designing custom 3D printed parts at home
    Pick: Prompt2CAD

    Prompt2CAD generates parametric models from text, exports as STL for 3D printing, and allows iterative tweaks easily.

  • VFX artist scanning a real prop for a game
    Pick: Polycam

    Polycam's LiDAR and photogrammetry produce detailed meshes with textures, exportable to OBJ/FBX for game engines.

Frequently Asked Questions

Prompt2CAD vs Polycam: which should you choose?

Choose Polycam if you need to turn real-world objects or spaces into 3D models or floor plans — it excels at reality capture from photos, LiDAR, and drones. Choose Prompt2CAD if you want to generate parametric CAD models from text descriptions without touching a 3D scanner or CAD software. They serve different stages of the design workflow: capture vs. ideation.

Can Polycam generate CAD files like STEP?

No, Polycam exports meshes (OBJ, STL) and point clouds, not parametric CAD. For STEP files, use Prompt2CAD.

Can Prompt2CAD scan my room?

No, Prompt2CAD generates models from text, not from real-world capture. For scanning, use Polycam.

Which tool is better for floor plans?

Polycam. It automatically generates floor plans with measurements from LiDAR scans or photo sets, with a dedicated editor.

Which tool is more affordable?

Polycam Pro is $12.50/month annually; Prompt2CAD Pro is $29/month. For heavy use, Polycam is cheaper.

Do both tools have free tiers?

Yes. Polycam's free tier limits exports; Prompt2CAD's free tier limits generations per month.

Can I use Prompt2CAD for precise mechanical parts?

Yes, it generates parametric CAD in real-world millimeters, but for high-tolerance assemblies, traditional CAD may be needed.

Does Polycam require LiDAR?

No, Polycam works with photos/video on any device. LiDAR improves accuracy and enables floor plans on iOS.

What are the latest features in Polycam?

HDRI lighting with 5 presets (default, daylight, overcast, sunset, colorful) and a floor plan editor with drag overlapping objects.
