FAQ: Preparing and Delivering 3D CAD Files for Dopple

Dopple uses 3D CAD files to create runtime-optimized, web-ready 3D models that power interactive product configurators and augmented reality (AR) tools. These models allow customers to visualize and customize products directly on your eCommerce platform.

Dopple reviews, processes, and optimizes your CAD files to create 3D assets suitable for online use. Dopple’s Subject Matter Experts (SMEs) ensure that the files meet the requirements for high-quality, efficient performance on your website.

Dopple can work with many file formats, but certain formats are preferred for optimal compatibility and efficiency (e.g., .glb, .gltf, .step, .fbx). 

Marketing teams typically initiate the process by working with internal engineering or product design teams, as these teams manage CAD files within their systems.

Provide examples of Dopple’s past work (e.g., Dopple’s motorcycle, bike, or boat demos) to illustrate the value of integrating 3D models into the customer journey. Highlight the potential to increase engagement and sales.

Dopple works with files from most major CAD systems, including:

• SolidWorks
• Autodesk Inventor
• Creo/ProE
• CATIA
• Siemens NX

The preferred file formats include:

• .glb/.gltf: Standardized 3D file format for optimal web use.
• .step/.stp: Universal CAD export format.
• .fbx: Commonly used for 3D model exchanges.
• .obj: Supported but less preferred due to material library complexities.

Dopple’s team can help simplify and optimize CAD files. Begin by removing unnecessary internal components and metadata to reduce file size before submission.

Ensure that all required subcomponents are included in the top-level assembly. Missing parts can cause delays during Dopple’s review process.

Follow these general steps:

1. Identify the top-level assembly for the product.
2. Export the assembly using the appropriate CAD software tools (e.g., Pack & Go for SolidWorks).
3. Save files in a preferred format, such as .step, .glb, or .fbx.
4. Compress all files into a .zip folder for easy delivery.

Files should be uploaded via Dopple’s secure file transfer system or any other agreed-upon method. Ensure all files are properly named and organized for efficient processing.

If CAD files aren’t available, Dopple can work with other file formats, such as .obj or .blend. However, the creation of a 3D model from scratch may incur additional time and costs.

• File preparation: 1–2 weeks (depends on your internal team).
• Dopple’s review and optimization: 2–4 weeks (varies based on file complexity and feedback loops).

 Once files are submitted, Dopple will:

• Analyze the files for completeness and compatibility.
• Optimize them for web and AR use.
• Provide a preview or prototype for feedback before final implementation.

Ensure the files reflect the current product version to avoid discrepancies in the 3D model. If only outdated files are available, Dopple may need additional input to update or correct the visualization.

Dopple prioritizes confidentiality and security. Sensitive data should be excluded or anonymized wherever possible. For further reassurance, consider executing a Non-Disclosure Agreement (NDA) with Dopple.

• Improved Engagement: Customers interact with 3D configurators longer, increasing the likelihood of a purchase.
• Higher Conversions: Dynamic visuals provide clarity, reducing decision-making friction.
• Reduced Returns: Accurate representations ensure customers receive what they expect.

 Success metrics include:

• Increased time spent on product pages.
• Higher add-to-cart and conversion rates.
• Reduced return rates.
