What is Scan to CAD?

Scan to CAD is a process that transforms physical objects into digital models. It involves using advanced scanning technologies to capture precise measurements and details of real-world objects and then converting this data into CAD-compatible digital models.

How it Works | Flow of Scan to CAD

The process begins with the acquisition of physical object data through scanning. Various scanning technologies, such as laser scanning and structured light scanning, are used to capture detailed information about the object’s geometry. This data is then processed and converted into a CAD-compatible format, allowing designers to manipulate and modify the digital model as needed.

Data Acquisition and Scanning

Utilize specialized scanning technologies, such as laser scanning or photogrammetry, to capture comprehensive data of physical objects or spaces, creating a detailed point cloud.

Point Cloud Cleanup and Processing

Clean up the point cloud data to remove noise and unwanted elements, ensuring accuracy and quality for the subsequent CAD conversion.

CAD Conversion and Surface Generation

Use CAD software to convert the cleaned point cloud data into a digital CAD model, defining surfaces, geometrical features, and textures based on the scanned information.

Model Refinement and Editing

Refine the initial CAD model through manual adjustments and editing, ensuring completeness, accuracy, and compatibility with CAD software standards.

Quality Assurance and Validation

Review and validate the final CAD model to ensure it meets specifications, matches the original object or space accurately, and is free of discrepancies or errors.

Delivery in Desired Format

Based on client requirements and intended usage of the CAD data, deliver the approved CAD model in the desired file format (e.g., STEP, IGES, DWG, OBJ, etc.).

Creating and Using the Model

Once the digital model is created, the possibilities are endless. Designers can use it for prototyping, visualization, analysis, and even manufacturing. It opens up a world of opportunities for innovation and creativity, allowing designers to bring their ideas to life like never before.

Conceptualization

Define project goals and requirements based on specifications, gather stakeholder input, and outline design objectives.

Initial Drafting

Use CAD software to create a preliminary design incorporating key features, dimensions, and components, which will serve as a foundation for further development.

Refinement & Detailing

Enhance design through iterative processes, adjusting for functionality, aesthetics, and manufacturability with fine-tuned dimensions and surface finishes.

Validation & Simulation

Conduct rigorous simulations and analyses to validate functionality, safety, and performance, including physical prototyping for real-world feasibility testing.

Collaboration & Documentation

Foster communication through collaborative reviews, incorporating feedback for continuous improvement while generating technical documentation for manufacturing guidance.

Manufacturing & Production

Utilize CAM software for toolpath generation, ensuring alignment with CAD model specifications and overseeing production for quality control.

Utilization & Maintenance

Integrate CAD model data for operational efficiency, supporting ongoing processes and performing updates as needed for continued relevance and effectiveness.

Digital Reverse Engineering Process

Object Acquisition

The first step in reverse engineering involves obtaining the physical object or system that needs to be analyzed and recreated digitally. This could be a mechanical component, a product, or a complex system like a machine or structure.

Data Capture

Using advanced technologies such as 3D scanning, laser scanning, or photogrammetry, detailed data about the object’s geometry, dimensions, texture, and features is captured. This data capture process generates a point cloud or a mesh model that accurately represents the physical object.

Data Processing

The captured data undergoes processing to clean up any noise, outliers, or unwanted elements that may have been captured during the data capture phase. This step is crucial for ensuring the accuracy and reliability of the subsequent CAD model.

CAD Modeling

The cleaned and processed data is then imported into CAD software, and a 3D CAD model is created based on the captured data. This involves defining surfaces, features, and dimensions to represent the physical object in digital form accurately. Additional details, textures, and colors may be added to the CAD model as needed to match the physical object.

Validation and Adjustment

The CAD model is validated against the physical object to ensure accuracy and completeness. Based on validation results and feedback from stakeholders or experts, any necessary adjustments or refinements to the CAD model are made.

Documentation

Technical documentation, drawings, and specifications are generated based on the CAD model. This documentation includes assembly instructions, part lists, and other relevant information that is crucial for manufacturing, assembly, or maintenance purposes.

Utilization

The digital CAD model is then utilized for various purposes, such as design modifications, simulations, analysis, prototyping, and production planning. It is integrated into the product development or engineering workflow for further iterations and improvements, ensuring the digital model remains up-to-date and aligned with project requirements.
