If it is system related, then I would check the graphics card.  Some graphics cards do not display as expected.  You can also check to see that you have the most up to date graphic card driver installed. ... View more

It is possible that the issue is specific to the complexity of the TIN.  Is this TIN more complex than the other project that worked? As a workaround, you can convert the TIN to raster and then run the Slope or Aspect tools. ... View more

Hi Elaine!  How are you going about changing the rendering?  Have you ensured that the new renderer is checked on in the symbology dialog?  Are you able to use any of the other renderers? Here is a good blog that discusses "Changing up the way a TIN is rendered". ... View more

Great code sample Darren.  Thanks for sharing! ... View more

You can convert the polygon file to a polyline file using the Split Line at Vertices tool.  Then Spatially Join the Polygon to the Polyline.  There will be a count field in the output. ... View more

You can change the Map and Display units for the data frame.  Right click the data frame > properties. Under the General tab there is the option to set the units.  There is also the option to change the scale settings (Scale Drop down > customize this list). ... View more

When creating the mosaic dataset you will need to change the Pixel Properties to 1 band and the Pixel type to match the data you are using. Create Mosaic Dataset (Data Management) ... View more

Depending upon the size of your rasters, you could use the Mosaic to New Raster tool to create a single raster dataset. If that is not an option, I would recommend adding the imagery to ArcGlobe as a draped layer.  Then add your elevation raster as an elevation layer.  You can remove the default elevation layers, and the aerials will be draped over your elevation raster. ...

Add the raster to ArcScene set the Base Heights from the Layer Properties to use the raster.  If there is not a big change in the elevation, you may need to set the vertical exaggeration of scene properties. ... View more

I cannot speak directly to the Raster to Polyline tool; however, the Raster to Polygon tool uses its own algorithm for simplification which is different than the two algorithms in the Simplify Polygon tool.  NIM013638 is an enhancement request for more information on the simplification algorithms of the Raster to Polygon tool. ...

I would recommend using the Trace tool.  The tool will follow along the line and snap to the vertices of the existing feature. Creating segments by tracing ... View more

Yes, with 10.0 there were some changes made to the 3D Analyst and Spatial Analyst toolbars. What happened to the Spatial Analyst toolbar? Why are my Spatial Analyst and 3D Analyst toolbars gray? You can access that tool from ArcToolbox > 3D Analyst Tools > 3D Features > Feature to 3D by Attribute. ... View more

Have you installed the latest service pack?  If this is with ArcGIS 10.0, try turning off the background processing (Geoprocessing menu > Geoprocessing options). ... View more

dIf I understand you correctly you can create a 3D buffer zone by modifying the symbology, and then use the Layer 3D to Feature Class tool to create a multipatch. Here is a document on the technique used in 10.0. In this example, the 3D analysis tools do not work in 9.3. Analyzing threats to 3D flight paths and corridors ... View more
