I'm working on search engine software to help engineers find 3D models on the web, and I'm interested in how you typically search -

*How often do you need to search the web for 3D models to use as part of a design? Where do you typically find what you need?

*Do you always know the name of part you need or the vendor? Do you ever find that you know what you need and have photo or drawing of it but don't know the exact name or what the vendor calls it?

Any input at all would be greatly appreciated! Thanks!
