The world of automotive customization and design is constantly evolving, with enthusiasts and professionals alike seeking innovative methods to bring their visions to life. 3D scanning technology has emerged as a game-changer in this realm, offering unparalleled precision and efficiency. In a recent insightful webinar, SHINING 3D expert Matt Perez showcased the power of the EinScan Pro HD handheld 3D scanner in transforming car modification workflows. He demonstrated how this versatile tool, paired with EXScan Pro software and Fusion 360, can streamline the process of scanning car parts for wide body designs and other customizations.
This article delves into the key takeaways from Matt’s webinar, providing a comprehensive guide on leveraging the EinScan Pro HD for automotive applications. Whether you’re a seasoned automotive designer or a car enthusiast eager to explore the possibilities of 3D scanning, this guide will illuminate how you can optimize your workflow and achieve exceptional results.
Mastering Car Part Scanning with EinScan Pro HD & EXScan Pro: A Step-by-Step Guide
Matt Perez expertly walked webinar attendees through the fundamental steps involved in 3D scanning and designing car parts. This process generally encompasses four key stages:
- Scanning the Car Part: Capturing the physical form of the car component using the EinScan Pro HD scanner.
- Mesh Processing: Refining the raw scan data within EXScan Pro software to create a clean and accurate 3D mesh.
- Coordinate System Alignment: Orienting the 3D mesh within a digital coordinate system for seamless integration with CAD software.
- 3D Model Design: Utilizing software like Fusion 360 to design modifications or new components based on the scanned data.
For larger automotive components like car bodies or panels, Matt recommended utilizing the rapid scan mode in conjunction with hybrid alignment. A crucial tip shared by Matt for successful large object scanning involves marker placement. Ensuring that at least four markers are consistently within the scanner’s light pattern is key for maintaining tracking and data accuracy during the scanning process. This technique is particularly vital when scanning complex automotive shapes and surfaces.
Once the scan data is processed and aligned within EXScan Pro, it’s ready for seamless import into Fusion 360 or other CAD software. This integration allows designers to immediately begin working with the accurate 3D representation of the scanned car part, paving the way for innovative design modifications and customizations.

Selecting the Optimal Scan Mode for Automotive 3D Scanning
The EinScan Pro HD’s versatility extends to its multiple scan modes, each designed to cater to different object sizes and scanning requirements. Understanding these modes is crucial for maximizing the scanner’s potential in automotive applications. The EinScan Pro HD offers three primary scan modes:
-
Fixed Scan Mode: This mode is ideal for smaller, stable car parts. The scanner is mounted on a tripod and often used with a turntable for automated 360-degree capture. Think of components like wheels, lights, or smaller trim pieces. The fixed scan mode prioritizes accuracy and detail for smaller objects.
-
Handheld Rapid Scan Mode: Perfect for larger, less easily moved objects – like entire car bodies or large body panels. In this mode, the user handholds the scanner and moves around the vehicle, much like filming a video. This mode emphasizes speed and efficiency for capturing large automotive structures.
-
Handheld HD Scan Mode: Similar in handheld operation to the rapid scan mode, but optimized for capturing intricate details. While still handheld, it provides higher resolution scans, making it suitable for complex car parts or areas requiring fine detail, such as grilles, emblems, or interior components.
The choice of scan mode directly impacts the speed, detail level, and suitability for different automotive scanning tasks.
Fine-Tuning 3D Scan Settings for Automotive Excellence
Each scan mode on the EinScan Pro HD offers a range of adjustable settings, enabling users to further optimize their scans for specific automotive needs.
Fixed Scan Mode Settings
The fixed scan mode includes unique settings like HDR (High Dynamic Range), which is invaluable for automotive parts with varying surface reflectivity, common in car interiors and exteriors. HDR helps capture detail in both bright and dark areas of the scan. The turntable option is another fixed mode exclusive, enabling semi-automated scanning. By placing a car part on a turntable, the software can rotate it incrementally, capturing data at set intervals (e.g., every 30 degrees) for a complete 360-degree scan. Markers can be placed on the object and/or turntable, allowing the software to automatically align individual scans with high precision.
Handheld HD Scan Mode Settings
Within the handheld HD scan mode, users can select between two operation modes: Classic and High-detail. Both modes operate at a standard speed of 10 frames per second (FPS). However, the High-detail mode necessitates a shorter working distance between the scanner and the car part to achieve its enhanced resolution. This mode is beneficial for capturing intricate surface details on automotive components.
Handheld Rapid Scan Mode Settings
The handheld rapid scan mode’s alignment process mirrors the HD mode, but its operation modes diverge to prioritize speed. It offers a Classic option, capturing at 15 FPS, a significant increase over the handheld HD mode. Furthermore, it includes Lightning and Lightning + Refine options. Lightning mode achieves an impressive 30 FPS at 1mm resolution using interpolation, while Lightning + Refine maintains the same 30 FPS but with refined data capture. It’s important to note that while rapid scan modes excel in speed, some fine details might be sacrificed compared to HD modes.
Optimizing Mesh Settings for Refined Automotive 3D Models
Post-scanning mesh settings within EXScan Pro play a critical role in refining the 3D model’s quality. Two key parameters to consider are Filter and Smooth. The Filter setting analyzes the generated mesh, identifying and处理 high and low-frequency noise. A lower filter setting is less aggressive, preserving more of the original scanned data. Conversely, a higher filter setting will more aggressively remove noise, potentially smoothing out finer details. The Smooth setting increases mesh density to create a smoother surface.
Matt demonstrated the impact of different mesh settings in his webinar by applying varying filter and smooth values to the same scan data. He recommended experimenting with low, medium, and high filter settings, combined with high smoothing, to understand their effects and tailor them to the specific requirements of the automotive part being scanned. This iterative approach allows for fine-tuning the mesh to achieve the desired balance between detail retention and surface smoothness.
