Would you mind sharing the data by posting the XYZ coordinates? I couldn't reproduce the issue with an arbitrary set of 4 nodes per TIN. Regards, Khalid H. Duri 3D Analyst Product Engineer Esri | 909.793.2853 x2747 ... View more

Can you try applying a slight buffer to the TIN domain output, then using the buffered polygon as your input to Extrude Between?  If this works, then you ran into a rarely encountered known issue that occurs along certain coincident boundary conditions. ... View more

Hi Chase, Please try the sun skymap tool available with 3D Samples to generate the output points and let me know if you have any other issues: http://links.esri.com/3dsamples It has been updated to no longer require PyEphem, and resolves a few bugs with the old tool.  Regards, Khalid ... View more

Hello Popescu, I have rolled out an updated sun skymap tool in the new 3D Samples which no longer requires PyEphem.  Please try this out instead and let me know if you have any trouble: http://links.esri.com/3d_samples Regards, Khalid ... View more

Hello Heuner, Grade in this context is indicated in percent units, not degree. ... View more

By chance, does your input data have its spatial reference defined? ... View more

Hmm... which tool's output is being passed into the Add Z Information tool? I suspect there may be an issue with how the preceeding tool's output layer definition may be getting updated. ... View more

You can run the Add Z Information tool to obtain slope if the geometry of your shapefile is either a polygon or multipatch and the rooftops are isolated. ... View more

Good morning Franklin, I'm only seeing the behavior you're describing occur when I connect a multipoint feature class.  With a single point feature, I see the Z option.  What version of the software are you using? ... View more

I dubbel checked to see if it is in symbology, but its not. In order to use the slope renderer, you have to add the renderer to the Symbology tab in Layer Properties. Follow these steps: 1. Right-click the TIN layer in the table of contents and select Properties. 2. Click the Symbology tab. 3. Uncheck the active renderer (i.e. Elevation or any other TIN face renderer that is checked). 4. Click Add. 5. Select the "Face slope with graduated color ramp" option and click Add. 7. Click Dismiss. 8. Select the Color Ramp drop-down and choose your desired color ramp then click OK. ... View more

The terrain dataset references data from the feature dataset it resides in, so there's no need to recreate points for it. You can obtain the slope and aspect information as polygons using the Surface Slope and Surface Aspect tools, then perform a spatial join to get them attributed to the points. If the Z values are stored in the geometry and not as an attribute, you can use Add Z Information to add it as an attribute. Let me know if you still need help. ... View more

Regarding the unexpected values, you may wish to perform some QA/QC checks on your data to determine if you have misclassified measurements. Try the Locate Outliers tool or the LAS Point Statistics as Raster tool with the Z Range option to get a sense for whether you have extraneous values.  If you manage to capture them using Locate Outliers, then you can optionally choose to reclassify those points using Set LAS Class Codes Using Features. Regarding your second question, the surface gets regularly sampled with points over the area defined by the polygon. The sampled points are interpolated using the method selected in the tool, then used to create a surface that matches the polygon's boundary. If you don't specify a sampling distance, the tool uses the densification of the LAS data as its sampling distance. ... View more

It looks like you might have a multipoint feature and not a single point feature. The options you get with multipoint features are Z Min, Z Max, Z Mean, & Point Count. You can create single point features from the multipoints using the Multipart to Singlepart tool. ... View more

Hello Stephen, You can setup a model that accomplishes this task in less than 2 minutes! Here's how: [ATTACH=CONFIG]26767[/ATTACH] Create a new model in a toolbox & edit it (happens automatically when you create the new model) Select the Insert menu > Iterators option & choose "Datasets" Edit Iterate Datasets so the Dataset Type parameter is set to "TIN" [ATTACH=CONFIG]26769[/ATTACH] Add the "Add Surface Information" tool, specify the input points, select the Z property, and set the "TIN" output from Iterate Datasets to the Surface parameter [ATTACH=CONFIG]26770[/ATTACH] Add the "Add Field" tool and specify the Name variable for the Field Name parameter with Field Type set to double [ATTACH=CONFIG]26771[/ATTACH] Add the "Calculate Field" tool, specify %Name% in Field Name parameter and Z field in Expression parameter Try the attached toolbox and let me know how it works out. Please note that if your file names are greater than 10 characters and the input file is a shapefile, the Add Field step will fail because the dbf format does not support field names larger than 10 characters.
