Grammarly for CAD. Upload your CAD export, describe your manufacturing setup, and CADly checks if your design is physically buildable, flags blockers, suggests fixes, and finds the cheapest build plan. One click. View source →

Cursor for Fusion 360

CADly is an AI-powered DFM (Design for Manufacturability) analysis tool that connects to Autodesk Fusion 360. It parses STEP/STL files, runs geometry analysis, detects manufacturing violations across FDM, CNC, and SLA processes, and provides auto-fix capabilities with cost comparison. Powered by a multi-model AI orchestration layer from Dedalus Labs.

Multi-model orchestration for specialized tasks

CADly routes each analysis step to the best-fit AI model. Geometry parsing goes to a fast model, DFM reasoning to a deep thinker, and cost estimation to a broad generalist. Users can pick presets (Auto, Speed, Accuracy, Max Intelligence) or go Custom.

Cost Reasoning
GPT-4o
Broad knowledge for cost estimation across FDM, CNC, and SLA. Compares material costs, machine time, and post-processing.

What powers the system

🛠

Python Backend

Core analysis engine built in Python. Parses STEP/STL geometry, runs constraint checks against manufacturing rules, generates violation reports with severity levels.

Web Frontend

Dark-themed dashboard with file upload, analysis tabs, violation cards with severity colors, process filters (FDM/CNC/SLA), and one-click auto-fix buttons.

Fusion 360 Integration

Direct connection to Autodesk Fusion 360 via scripting API. Reads design parameters, applies fixes back to the model, and validates changes in context.

Cost Comparison

Estimates manufacturing cost across all supported processes. Factors in material, machine time, post-processing, and failure risk to recommend the cheapest viable build path.

From CAD file to build plan in seconds

01

Upload

Drop your STEP or STL export. Describe your available machines (FDM printer specs, CNC mill tolerances, materials on hand).

02

Parse

Gemini Flash extracts geometry features: wall thicknesses, hole diameters, corner radii, overhangs, unsupported spans.

03

Analyze

Claude Sonnet checks every feature against manufacturing constraints for FDM, CNC, and SLA. Flags critical violations, warnings, and suggestions.

04

Fix

One-click auto-fix adjusts parameters (wall thickness, hole diameter, corner radius) to meet requirements. Pushes changes back to Fusion 360.

05

Compare

GPT-4o estimates cost across all viable processes. Recommends the cheapest build plan that passes all constraints.
