Whisker

Product Introduction

1. Definition: Whisker is a cloud-based, AI-powered parametric CAD (Computer-Aided Design) generation platform. It falls under the technical category of Generative Design and Automated CAD Engineering, leveraging a multi-agent AI pipeline to transform natural language prompts, images, or meshes into production-ready Boundary Representation (B-Rep) geometry.

2. Core Value Proposition: Whisker exists to eliminate the bottleneck of manual feature construction in traditional CAD workflows. By utilizing "Text-to-CAD" and "Photo-to-CAD" technologies, it allows engineers and designers to generate complex, editable 3D models in under 60 seconds. Its primary value lies in providing fully parametric outputs—where every dimension is a tunable variable—rather than static, uneditable meshes, bridging the gap between artificial intelligence and professional mechanical engineering.

Main Features

1. Multi-Agent AI Generation & Verification Pipeline: Whisker employs a sophisticated multi-stage architecture. A "Generator Agent" interprets natural language inputs to write parametric code; an "Executor Agent" builds the 3D geometry within a sandboxed CAD kernel; and a "Vision Verifier" utilizes AI-driven image analysis to inspect the model from multiple angles against the original prompt. If errors are detected, a "Fixer Agent" iteratively refines the code until the geometry passes verification.

2. Real B-Rep Geometry & Manufacturing-Ready Output: Unlike standard AI generators that produce low-fidelity STL meshes or point clouds, Whisker generates true B-Rep (Boundary Representation) solids. This ensures the geometry is mathematically precise, supporting professional-grade operations such as fillets, chamfers, shells, and Boolean subtractions. The models are directly compatible with CNC machining, injection molding, and high-precision 3D printing.

3. Native Fusion 360 & CAD Interoperability: A standout technical feature is the ability to export models with a full feature tree and linked user parameters. Users can move their AI-generated designs into Autodesk Fusion 360, OnShape, or SOLIDWORKS (via STEP) while retaining the ability to modify original dimensions, sketches, and constraints. This "Interoperable Representation" (IR) format ensures that the AI's output is not a "dumb solid" but a smart, editable design asset.

4. Multi-Modal Input (Photo & Mesh-to-Parametric): Whisker supports diverse input streams beyond text. The "Photo-to-CAD" feature allows users to upload a 2D image and receive a 3D parametric equivalent. Additionally, the "STL to Parametric" capability enables users to import legacy mesh files and have the AI rebuild them as smart models with adjustable dimensions and feature history.

Problems Solved

1. Pain Point: Excessive Manual Modeling Time: Traditional CAD modeling for standard components (like enclosures, heat sinks, or brackets) requires hours of manual sketching and constraint mapping. Whisker reduces this to roughly 30 seconds, offering a 10x increase in prototyping speed for mechanical engineers and product designers.

2. Target Audience:

• Mechanical Engineers: Requiring rapid generation of standard components like NEMA motor mounts, pipe fittings, and heat sinks.
• Robotics Designers: Needing custom enclosures, brackets, and articulated assemblies with specific geometric constraints.
• AEC (Architecture, Engineering, Construction) Professionals: Seeking parametric architectural elements or custom fasteners.
• Hobbyists & Makers: Who may lack the technical expertise to use complex CAD software but need functional, 3D-printable parts.

3. Use Cases:

• Electronics Enclosure Design: Generating bespoke cases with specific wall thicknesses, standoff bosses, and ventilation slots.
• Rapid Prototyping: Iterating through different sizes of a mechanical part (e.g., a pillow block or handwheel) by simply changing natural language parameters.
• Legacy Data Recovery: Converting static STL files from 3D scanning or online repositories into editable, parametric STEP files.

Unique Advantages

1. Differentiation from Competitors: Most AI 3D tools focus on "Creative/Artistic" meshes (polygons) which are useless for mechanical engineering. Whisker differentiates itself by focusing on "Engineering CAD," providing the exact constraints, tolerances, and feature trees required by professional manufacturing environments.

2. Key Innovation: The Iterative Fixer Agent: The most significant technological leap is Whisker's self-correcting loop. By using a vision-based verification system to "look" at the generated model and comparing it against the physical constraints of the prompt, Whisker can self-heal geometry errors (like self-intersecting loops or failed fillets) before the user ever sees the model.

Frequently Asked Questions (FAQ)

1. Is Whisker CAD output compatible with professional software like Fusion 360 and SOLIDWORKS? Yes. Whisker supports one-click exports to STEP and STL formats for universal compatibility. Specifically, for Fusion 360, it provides a native parametric feature tree and user parameters, allowing for full professional editing and integration into larger assemblies.

2. How does Whisker differ from traditional generative design tools? Traditional generative design requires the user to define complex load cases and boundary conditions to find an optimal shape. Whisker is a "Natural Language Parametric" tool that builds geometry based on descriptive intent (e.g., "a 50mm flange with 4 M4 holes"), focusing on speed and ease of construction rather than structural topology optimization.

3. Can I edit the dimensions of a model after the AI generates it? Absolutely. Whisker provides a dedicated "Parametric Control" interface where every dimension (height, bore, wall thickness, etc.) is presented as a tunable slider. Any change to these parameters triggers an immediate re-execution of the model logic to update the geometry.

4. What is the difference between B-Rep and Mesh in AI-generated 3D models? Mesh models (like STL) are made of thousands of flat triangles, making them difficult to edit or use for precise engineering. B-Rep (Boundary Representation) geometry used by Whisker uses mathematical curves and surfaces, which are required for high-quality manufacturing, CNC toolpathing, and professional CAD workflows.
