2. KCAIUG City Planning and Development- Kansas City, MO 3D Analyst2 What can you do with 3D Analyst? Create realistic surface models from multiple input sources Determine height at any location on a surface Find what is visible from an observation point Calculate the volumetric difference between two surfaces (cut and fill) Working with 3D vector features to make realistic models of the 3D world Visualize your data in 3D and much, much more…..

3. KCAIUG City Planning and Development- Kansas City, MO 3D Analyst3 How to create a realistic surface model form multiple sources. Making a quick 3D model. Showing data in a 3D to be visualized.

4. KCAIUG City Planning and Development- Kansas City, MO 3D Analyst4 Making a quick surface model from multiple sources Two types of surfaces can be used in 3D Analyst 1.Grids (A matrix of square cells) 2.TINs (Triangulated Irregular Network) nonoverlapping triangles What can be used to make a surface? Surfaces can be created from a wide variety of data sources. You can make grids by importing USGS DEMs, DTED files, ASCII files, or even image formats. TINs can be created from points, lines, polygons, and Grids.

5. KCAIUG City Planning and Development- Kansas City, MO 3D Analyst5 Making a TIN from Points and Lines. You must have elevation data (Z value) with your shapefiles in order to create a TIN. To make a simple surface model you will need- At least a shapefile with elevation data (Z Value).

6. KCAIUG City Planning and Development- Kansas City, MO 3D Analyst6 Select Create TIN Make sure that the theme or themes you wish to use are active Select which features you want to define info for. Choose what kind of input brakelines or mass points Choose your source of elevation from the table here.

7. KCAIUG City Planning and Development- Kansas City, MO 3D Analyst7 You will be asked to give a location to save your TIN. Your new Tin will be placed in your view. Your new surface is ready.

8. KCAIUG City Planning and Development- Kansas City, MO 3D Analyst8 To View your surface in 3D Go to view and select 3D scene. 3D Scene window will appear with your data. You can move around your surface and themes. Change sun location and much more…..

9. KCAIUG City Planning and Development- Kansas City, MO 3D Analyst9 Making a quick 3D model. The city of Kansas City, Missouri has been working on a 3D model of the center city (the loop) to Crown Center. The reason ArcView is being used is its quick way of making a model over other software programs such as MicroStation.

10. KCAIUG City Planning and Development- Kansas City, MO 3D Analyst10 The building information was collected by a city worker for the number of floors in each building. There is also the problem that not all buildings have the same height between floors as other buildings. For example the new Federal Court House is only 9 Stories tall, but is about 20 feet per story while City Hall is 30 stories tall, but is about 10 feet per story. Since this effects the look of a building this information was collected as well (mostly estimated).

11. KCAIUG City Planning and Development- Kansas City, MO 3D Analyst11 The building shapes are from the city planimetric data of the last fly over. A in-house avenue script allows us to click on a building in the view and add its number of stories and floor height to a database. Once the information is collected and entered you can start to view the buildings 3D. There does not have to be a surface present to view the buildings in 3D.

12. KCAIUG City Planning and Development- Kansas City, MO 3D Analyst12 There is one down fall of using the building foot prints. Some of the buildings are shown as simple blocks but are really complex. A Method called the wedding cake is applied, by adding many polygons in different shapes to show a building. City Hall shows up as a box. When it is not in real life. The Jackson County Court House is shown as it appears in real life.

13. KCAIUG City Planning and Development- Kansas City, MO 3D Analyst13 Once you have your data it is simple to view your new buildings in 3D. As like before you need to select a 3D scene to view your data. Once your scene is active you will need to make your builds appear 3D.

14. KCAIUG City Planning and Development- Kansas City, MO 3D Analyst14 Make sure the building theme is active. Then go to theme and 3d Properties.

15. KCAIUG City Planning and Development- Kansas City, MO 3D Analyst15 This the base heights for you data. If you are not using a surface use zero. To make the buildings 3D click on the calc. Button. The expression builder is where you assign the buildings their height. We use our stories times the floor height.

17. KCAIUG City Planning and Development- Kansas City, MO 3D Analyst17 Other Types of Data can be used too. You can use data such as population patterns or growth to be view 3D.
