Have I mentioned that Raster Design is now included in the Infrastructure Design Suite?
Earlier this week, I posted some of my favorite uses for Raster Design, Merging Tiled Images and Cropping Aerial Imagery. Today, I want to talk about taking scanned sketches and giving them geographic intelligence.
Remember this guy? That guy that likes tracing paper, colored pencils and pentel sign pens? We met him over in Alignments from the Land Planners Curves.
Well, he’s awesome and everything, but I don’t always know what to do with his sketches. Using a combination of Raster Design, Infrastructure Modeler and Civil 3D, I can take his ideas and use them to get my model started.
(I actually show this workflow quickly in this video from our media launch (starting around minute 10) and mentioned it in a post called Breathing Some Life Into Infrastructure Planning)
Georeferencing Scanned Images, Especially Pencil Sketches
Insert the scanned image and just place it somewhere near the area it belongs. It is useful if you scan the tracing paper while taped to some sort of print out of a map or base plan like the image below. (The blue and green interchanges are pen sketches on tracing paper over a print out of my basemap.)
Of course, I wasn’t that smart for the example I have queued up for this post, but we’ll go with it.
Next use any combination of the Raster Design tools Match, Rubber Sheet, Scale, or Displace to get your sketch lined up where you need it.
Once you have the image where you want it, use Image Export to create a new image of the sketch, and include the creation of a world file.
I can continue to use it in the Civil 3D environment, or I can use it other places- like Infrastructure Modeler.
If your planner has multiple sketches, you can built them as proposals in Infrastructure Modeler and use Autodesk 360 Infrastructure Modeler to share those proposals with your team.
If I want to take those conceptual centerlines back to Civil 3D to work on early stage design, I can use the IMX export from Infrastructure Modeler, then IMX import into Civil 3D. The yellow centerlines in the Civil 3D model are alignments. I can use some of the techniques I talked about in Alignments from the Land Planners Curves to begin some early corridor modeling and more detailed feasibility analysis.
James will touch on this workflow in our upcoming CE News webcast on June 28, 2012 called: Planning and Environmental Assessment with BIM for Infrastructure. That’s TODAY! Don’t forget!
