As its name suggests, this is a service for the recruiting of CAD designers and engineers. The site works as a kind of marketplace in which you can post contract work for freelancers and teams throughout the world to ponder on, and then submit their own bids. You will then be able to review all the bids that materialize, and then select the designers/engineers that you deem as better-qualified. And they will be paid only when the work is fully done – something that can be easily ascertained as the site comes with the tools and resources for tracking the way work is progressing.
The work that is posted on the site ranges from simple 2D designs to complex 3D pieces, and you can be as specific as you wish when posting it. The site has a databank amounting to more than 10,000 engineers already.
CADCrowd accounts can be created for free. And as I mentioned at the beginning, CADCrowd is a worldwide service. You will be able to post projects no matter where you are located, and get to work with engineering talent the world over as if it were just around the block.
