As a surfer, I really wanted to see how the most recent bathymetry data (2m/pixel resolution) would look for the world-famous Mavericks big-wave surf spot, about 2 miles offshore of Princeton-by-the Sea in Half Moon Bay. As a learning content developer for InfraWorks 360, I also wanted to see what other fun things we could do with this data, such as visualizing and designing InfraWorks 360 models focused on navigation safety, coastal erosion and sea level rise, fisheries, even earthquake and tsunami hazards.
Turns out, bringing GeoTIFFs of ocean topography into my InfraWorks 360 model was way simpler than I thought it would be. Plus, with the right aerial imagery, you can even see waves breaking on top of underwater reefs. Here's a peek:

Making Your AutoCAD Civil 3D Project Shine, Part 1 showed you how to bring your AutoCAD Civil 3D project into a data-rich InfraWorks 360 model of the project's real-world location. In this follow-up post, let's talk about what to do, now that you've brought your infrastructure design project from AutoCAD Civil 3D into InfraWorks 360.
With the latest release of Autodesk InfraWorks 360, you can import a polygonal area of interest in SHP file format to specify the extents of a Model Builder model.
Autodesk's Cristina Savian recently published a helpful article about how to do this, using AutoCAD Map 3D or AutoCAD Civil 3D to create a polygon that you can import into the Model Builder to define your InfraWorks 360 model.
Check out her article, and remember these guidelines:
When you import a SHP file with a single polygon, Model Builder converts the polygon to an area of interest that you can select and edit.
When you import multiple polygons in the same SHP file, Model Builder displays areas of interest wherever there are polygons in your SHP file. When you select an individual polygon, Model Builder converts it into an area of interest that you can edit. You can only use one area of interest at a time.
Model Builder converts multi-ringed polygons to individual polygons.
If your SHP file does not contain any polygons, Model Builder is unable to draw areas of interest on the map.
Model Builder does not allow you to select polygons that have more 1000 vertices, or polygons that intersect themselves.
Model Builder supports model areas up to 200 square kilometers or lengths up to 200 kilometers in latitude or longitude.
