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.
Turn plain text into editable, parametric 3D CAD models you can actually work with.

Prompt2CAD
0 mentions · 65% positive
What users praise
- • Generates real parametric CAD from plain text instantly.
- • Browser-based: no install, works on any device.
- • Exports to STEP, DXF, OBJ, STL, GLB for interoperability.
- • Parametric sliders allow real-time dimension adjustments.
What frustrates them
- • Geometry can be unpredictable and require manual cleanup.
- • No user community or support channels available.
- • Limited to simple parts; complex assemblies fail.
- • AI often misinterpret prompts needing multiple iterations.

Hacker News, YouTube, Product Hunt, App Store
What users praise
- • Fast, easy LiDAR scans with minimal learning curve.
- • Generates mesh, floor plan, and idealized model from one scan.
- • Cross-platform with iOS, Android, and web support.
- • Free tier includes valuable tools like AI generator and Gaussian splat.
What frustrates them
- • Scan reliability is spotty: failed uploads, lost tracking, backdrop capture.
- • Dimensions and full floor plans locked behind $400 paywall.
- • Curved walls and stairs render angular, forcing Matterport for pros.
- • Confusing free/paid feature split, feels like dark patterns.

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 scenePick: 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 homePick: 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 gamePick: 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.
