Background Theory > 3D > Sources of 3D Electronic Part Models

Obtaining 3D electronic part models is essential for designing and simulating electronic circuits and PCB (Printed Circuit Board) layouts accurately. Here are some common sources where you can find 3D electronic part models:

Manufacturer Websites: Many electronic component manufacturers provide 3D models of their components on their websites. Look for a "CAD Models" or "Downloads" section on the manufacturer's website. Common manufacturers such as Texas Instruments, STMicroelectronics, and Analog Devices often provide 3D models for their components.

Component Distributor Websites: Electronics component distributors like Digi-Key, Mouser, and Newark often provide 3D models for the parts they sell. You can search for the component you need on their websites and download the associated 3D model.

CAD Model Repositories:

GrabCAD: GrabCAD is a community-driven platform where engineers and designers share CAD models, including 3D electronic component models. Visit the website.

TraceParts: TraceParts is an online CAD parts library that includes a wide range of electronic component models. Visit the website.

3D ContentCentral: This is a service provided by SOLIDWORKS where users can share and access 3D CAD models, including electronic components.https: //www.3dcontentcentral.com/

Online 3D Model Libraries:

Thingiverse: While primarily focused on 3D printing, Thingiverse also has a collection of electronic component models shared by users. Visit the website.

YouMagine: Similar to Thingiverse, YouMagine has a community-contributed collection of 3D electronic component models. Visit the website.

Online Forums and Communities: Online forums and communities dedicated to electronics and CAD design often have sections where users share 3D component models. Websites like the EAGLE forum, KiCad forum, or Stack Exchange's Electrical Engineering Stack Exchange may have user-contributed models or links to external sources.

3D CAD Model Software: Some software tools, such as FreeCAD, offer features for generating 3D models of electronic components. You can create custom 3D models if the specific component isn't available in existing libraries.

Custom Modeling Services: If you can't find a 3D model for a specific component, you can consider hiring a 3D modeling service or freelancer to create a custom model based on the component's data-sheet and specifications.

Use with Caution

When using 3D electronic part models, it's important to verify their accuracy and compatibility with your CAD software and design requirements. Always check the source's terms of use or licensing agreements to ensure you have the right to use the models in your projects.
