Backflip AI

What is Backflip AI?

Backflip AI is an AI CAD tool designed for mechanical design, reverse engineering, and product development. Its main capability lies in converting 3D scans or triangular mesh models into editable parametric CAD models, rather than merely generating polygonal meshes that resemble the original shape.

The system attempts to infer the modeling steps carried out by the engineer, and generates features such as stretching, rotation, arraying, chamfering, and rounding. The result is a feature tree that includes sketches, constraints, and design history; this tree can also be exported in STEP format for use in existing manufacturing processes.

Who is Backflip AI suitable for?

• Mechanical engineer: Reconstructs the scanned data into parametric parts that can be further modified.
• Product designer: Quickly convert the physical prototype into a foundation for subsequent design work.
• Reverse engineering team: reduces the time required to manually redraw sketches and features from meshes.
• 3D scanning services: deliver CAD models that are easier to edit for clients.
• Manufacturing companies: Transfer old parts, spare components, and on-site scanning data into digital formats.
• Additive manufacturing users: Revise the scan model before performing the manufacturability check and printing.
• Education and maker users: Learn about the relationship between scanning, feature modeling, and CAD editing.
• Hardware startup teams: accelerate prototype iteration, component adaptation, and design validation.

Current main functions

• 3D scanning to CAD: Automatically reconstructing the scanned mesh into engineering geometry.
• Parametric feature tree: It retains the modeling steps, making it easy to return to the feature level for modifications.
• Logical sketch constraints: Attempt to establish dimensions, geometric relationships, and external references.
• Engineering feature inference: Combining operations such as stretching, rotation, arraying, chamfering, and rounding.
• Fusion plugin: Utilizes AI-based reconstruction capabilities within the Autodesk Fusion workflow.
• Web application: It is possible to submit tasks and view results without first installing a complete plugin.
• STEP export: Transfer the results to other common CAD and manufacturing software.
• Task mode selection: Use Fast Mode or Thinking Mode to balance cost and the depth of reasoning.

Supported input and output formats

What is the difference between parametric CAD and regular grids?

Fast Mode and Thinking Mode

In Fast Mode, 10 points are spent per task, making it suitable for models with a simple structure or those that require rapid trial and error. In Thinking Mode, 50 points are spent per task, which is appropriate for situations where the system is expected to allocate more computing resources to handle complex structures.

How to use the web interface to convert scans into CAD format

1. Register for a Backflip account and access the web application.
2. Prepare STL, OBJ, GLB, GLTF, or PLY files, and check the orientation and integrity of the model.
3. Remove irrelevant backgrounds, floating patches, and obvious scanning noise.
4. Upload the grid and select either Fast or Thinking mode based on the complexity of the structure.
5. Wait for the system to generate the parametric model and feature tree.
6. Check whether the sketches, dimensions, references, stretches, rotations, and arrays meet the design requirements.
7. Export the native result or STEP file to make further modifications in CAD software.
8. It is used in production only after size verification, interference checks, and manufacturing validation have been completed.

Usage process of the Fusion plugin

1. Verify that the Fusion version, operating system, and organizational installation permissions meet the requirements of the plugin.
2. Obtain and install the official Fusion plugin from the Backflip account.
3. Open the target project in Fusion and activate the Backflip function panel.
4. Import or select the scan mesh that needs to be reconstructed.
5. Submit the task and select the appropriate generation mode.
6. Load the generated results into the design environment and examine the timeline and sketch constraints layer by layer.
7. Redesignate the critical dimensions and correct any unreasonable references or feature orders.
8. Save a version first, then proceed to the assembly, simulation, engineering drawing, or manufacturing modules.

Increase the success rate of converting scans to CAD.

• Complete coverage: Data is collected from multiple angles to minimize gaps and severe occlusions.
• Accurate proportions: Known dimensions or reference objects are retained to facilitate verification of the actual size.
• Noise is controllable: outliers, background objects, and floating geometry are removed.
• Clear surface: Prevent scanning errors caused by reflections, transparency, and insufficient texture.
• Appropriate orientation: Aligning the main plane with the coordinate axes reduces the difficulty of feature recognition.
• Moderate simplification: Control the number of surface patches while retaining holes, rounded corners, and key boundaries.
• Component separation: Complex assemblies should be broken down into individual components for separate reconstruction.
• Keep the original file: Any cleaning up or simplification is done on a copy, allowing for easy attempts again.

Models suitable for processing

• Mechanical parts with planar, cylindrical, perforated shapes and symmetrical structures.
• Common engineering models that consist of stretching, rotation, arraying, chamfering, and rounding.
• Old parts with a history of design changes, as well as spare parts that are no longer in production, need to be restored.
• A physical prototype that has been scanned properly and features clear boundaries.
• Manufacturing parts that need to be imported using Fusion or processed through STEP.
• Parts that require adjustments to their dimensions or the addition of features based on their original shape.

Models that are not very suitable

• Highly irregular shapes such as hair, fabric, plants, and natural rocks.
• Scan data with many missing areas, damaged topology, or severe noise.
• Artistic models that contain numerous fine textures but lack distinct engineering features.
• A complex assembly scan in which multiple parts are interwoven with one another without being separated.
• A vehicle exterior that requires strict surface continuity and Class A surface quality.
• Safety-critical components that must be produced in a single batch to enable immediate deployment.

Typical use cases

• Replication of spare parts: Scanning is used to retrieve parts for which the original drawings are not available, in order to create editable models.
• Fixture adaptation: Design matching fixtures based on the scanning of objects or workpieces on site.
• Product modification: Adjusting the hole positions, dimensions, or mounting interfaces based on the existing product.
• Quality analysis: The scan results are converted into CAD format and compared with the nominal design.
• Ergonomic design: The physical contact surfaces are used to assist in creating subsequent engineering models.
• Repair and maintenance: Create digital part catalogs for older equipment.
• Prototype digitization: Converting manual models or rapidly printed versions into a basis for design.
• Educational demonstration: Shows the differences between grids, entities, feature trees, and constraints.
