Having this metadata in the DWF will allow us to hook into selection events in the 2D view and create a connection between what's selected in 2D and displayed in 3D. The data being published in this sample is simple enough - the handle of the object and the material applied to it. The idea is that during the publishing of your model from AutoCAD, you add some metadata to objects (in this case I'm using 3D solids) as they get published both into 2D and 3D sheets. So here's what I've been playing around with - primarily intended to be part of the Component Technologies webcast material I mentioned in a post a few weeks ago. If you throw in the capabilities of AutoCAD's DWF Metadata API (which allows you to add in custom metadata into both 2D and 3D DWF sheets, as they're being published) you really get some interesting possibilities for applications working on "downstream" data.Ī quick aside - if you're thinking of embedding the DWF Viewer in your application, be sure to check out the API documentation.
The latest release (version 7), especially, has some really cool API capabilities: while you've been able to respond to selection events in 2D views for some time, it's now also possible to manipulate 3D views, selecting which objects should be displayed. I haven't written about the API capabilities of the DWF Viewer, as yet, but this is a technology I really enjoy working with.
