Read the following for some i-drop content application:

From kitchen sinks and custom furniture to hydraulic components and mechanical fasteners, designers require pre-drawn content. With i-drop® technology-an XML-based technology invented by Autodesk for programmers and developers-you can provide easy access to design content over the Web. When you i-drop enable content, designers can drag it from the Web and drop it into their drawing window in one convenient step.

For example, your customer is a lighting designer who requires a specific lighting fixture. The customer can browse your online library of products and then drag the appropriate fixture as a block into an AutoCAD® drawing. Do your customers use Autodesk® Architectural Desktop styles as well? No problem. i-drop technology supports many types of content including Autodesk Architectural Desktop styles, AutoCAD blocks, Autodesk Inventor parts and assemblies, 3D Studio, and much more, so you can include as many types of content as you want.

Let's take it a step further. In addition to the geometry of a predefined object, you can i-drop enable associated data files, such as pricing information and order forms, and bundle them with the actual design content in the same handy i-drop package. Plus you can automatically tag your i-drop content with the source URL or any other web location of your choice.
