Searching by shape for 3D models on the web
I'm working on 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?
*If you needed a 3D model and could search using the shape of what you needed rather than the name, would you typically have a base 3D model you could use as input? A 2D drawing? A photo?
Any input at all would be greatly appreciated! Thanks!
