Do you ever reverse engineer off the shelf components that you use in your final assemblies? How much time and detail have you dedicated to parts that you will end up purchasing? You can save yourself some time by downloading official supplier models available from 3dcontentcentral.com.
Simply browse through the supplier list, register, and start downloading. Registration is free and you do not have to be a SolidWorks customer. If you do not have a supplier in mind, you can also browse the site by category to find a supplier.
Aside from downloading models, you can also contribute your own models to share with the SolidWorks Community. Here you will also find a user library that is full of random part and assembly models ranging from hardware to clip art, and everything in between.
When you register for an account it will allow you to rate the models that you have downloaded, and make requests for models that you would like others to post.
