What Is Scan to 3D in SolidWorks?

Scan to 3D is an essential feature in SolidWorks that allows users to create a 3D model from physical objects. It is a powerful tool that can be used in various industries such as manufacturing, product design, reverse engineering, and more. In this article, we will explore what Scan to 3D is all about and how it can benefit you in your design process.

What is Scan to 3D?

The Scan to 3D feature in SolidWorks enables users to transform physical objects into digital models. It uses a combination of scanning hardware and software algorithms to capture the geometry of an object and convert it into a 3D CAD model. This process is known as reverse engineering, where the physical object is analyzed and recreated digitally.

Why use Scan to 3D?

The use of Scan to 3D brings numerous advantages to the design process:

  • Time-saving: Instead of manually measuring and recreating complex geometries, Scan to 3D allows you to quickly capture the data of an object without tedious measurements.
  • Precision: The scanned data provides accurate measurements, ensuring that your digital model matches the physical object with high precision.
  • Design optimization: With Scan to 3D, you can easily analyze existing products or components for improvement or modification without having access to their original CAD files.
  • Quick prototyping: By scanning existing objects, you can rapidly create prototypes or modify designs without starting from scratch, saving time and resources.

The Process

To use Scan to 3D effectively in SolidWorks, you need both hardware and software components.

Hardware Requirements

The hardware typically involves a 3D scanner, which can range from handheld devices to stationary scanners. The choice of scanner depends on the size and complexity of the objects you intend to scan. Some scanners use lasers or structured light to capture data, while others use contact probes for more precise measurements.

Software Workflow

1. Scanning:

The first step is to scan the physical object using the 3D scanner. The scanner captures various data points on the object’s surface and creates a point cloud representation of its geometry.

2. Point Cloud Processing:

Once the scanning is complete, the point cloud data is imported into SolidWorks using the ScanTo3D tool. This tool can be accessed from the Add-Ins tab in SolidWorks.

The software processes the point cloud data and converts it into a usable format for creating a 3D model.

3. Creating Surfaces:

In this step, you define surfaces based on the processed point cloud data. You can create surfaces manually or use automated tools like Boundary Surface or Lofted Surface depending on your requirements.

4. Refining Geometry:

After creating surfaces, you may need to refine and edit them further by adding fillets, chamfers, or making adjustments for accuracy.

5. Creating Solid Models:

If your design requires solid models instead of surfaces, you can convert your surface model into solids using features like thicken or knit in SolidWorks.

Tips for Successful Scan to 3D

  • Clean the object: Before scanning, ensure that the object is free from debris, dust, or any reflective surfaces that may affect the accuracy of the scan.
  • Scan from multiple angles: To capture the complete geometry of an object, it is advisable to scan it from multiple angles. This helps in capturing hidden features and ensuring accuracy.
  • Use reference points: When aligning multiple scans, using reference points on the object or using a positioning system can help improve alignment accuracy.
  • Consider software limitations: Different software may have limitations on the size or complexity of objects that can be scanned. Before starting a project, make sure to understand these limitations to avoid any issues later on.

In conclusion, Scan to 3D is a valuable tool for creating digital models from physical objects in SolidWorks. It saves time, improves precision, and provides flexibility in design iterations. By following the proper scanning techniques and leveraging SolidWorks’ powerful tools for surface creation and refinement, you can unlock a whole new dimension for your design process.
