![]() You need to change the type of file to all files in order to see this file format. The default units are in Millimeters when opening Rhino but this is not useful with most GIS data. Note: It is recommended that you only export one layer at a time, particularly when exporting topography or buildings. Depending on how big your file is, this might take some time. Save your file (the only option is VRML format). Once you have your 3D data imported in ArcScene, go to File > Export Scene > 3D. It is recommended that you make a selection of the area you wish to model before exporting, so you will not export large amounts of unnecessary data. For New York City, a multipatch database can be found under the Department of City Planning website. This data includes details such as roof setbacks and roof slopes. Other files called Multipatch files can be imported that already contain detailed 3D information. ![]() If you started with a point file, they will be extruded to lines.) ![]() (If you started with a line file, they will be extruded to planes. Each of your layer's polygons will be extruded to volumes. Your layer should now look something like the image below. In the drop down menu Apply Extrusion by: choose the option adding it to each feature's minimum height. We will apply the extrusion by adding it to the feature's minumum height. (In the example below, the data layer will be extruded by values in the HEIGHT_ROO field.) When you are finished building your expression, click OK. You can also manipulate its extrusion through any of the mathematic functions in the Functions box or using the calculator buttons on the right. You can extrude your layer based on any of these fields by double-clicking its name in the Fields box. Note that the Fields box on the left contains the data fields associated with this layer. The Expression Builder dialogue box will appear. Then click the calculator button (on the right) to select or calculate your extrusion heights. Go to the Extrusions tab, and check that you would like to Extrude features in layer. The functions in this tab operate the same as those in ArcMap.) (Note that one of the tabs in the resulting dialogue box is named Symbology. Right click on your data layer name in the table of contents and select Properties. This is because you have not yet assigned an attribute with which ArcScene will create volumes.Īdding 3D attributes to your map works much like changing or adding symbology to a 2D project in ArcMap. It will probably appear floating askew, without any volumes. Once you've added your data, it will appear in the window. You do this exactly the same way as you would in ArcMap, using the Add Data button in the main toolbar. (You will find it at Programs > ArcGIS > ArcScene.) Notice that the interface is very similar to that of ArcMap.Īdd Data.
