The extension has not been activated. In ArcGIS, you can add any desired toolbar to the GUI. However, a few require the activation of an extension, similar to that found in ArcView 3.x.

Navigate to Tools > Extensions, check the necessary extension(s), and click Ok.

In ArcScene, when a vector layer uses a raster as a source for its base heights, the base heights are calculated based on the maximum resolution of the raster. When a raster is set to its own base heights, the raster is 'down-sampled'. There can be a mismatch between the z-value of the surface and the draped vector.

It is possible to use the maximum resolution of the raster, for its own base heights. Use the Raster Resolution button on the Base Heights tab in the Layer Properties dialog to changes its resolution. However, be aware that the higher the resolution used for the base heights will decrease the performance of ArcScene.

Yes. In 3D Analyst you can select Create/Modify TIN and go to the 'Add Features to TIN...' dialog which will allow you to edit the TIN file or save the changes to a new dataset.

Yes. At the 9.0 release of ArcGIS, TINs are displayed by default using the rendering combo of Edge types and Faces. At previous releases of ArcGIS, TIN display in ArcScene defaulted to Edge types and Elevation. The 9.0 change in the default TIN renderer combo was made for performance reasons and the new method is considered simpler and in most cases will draw faster.

There are many factors that influence the ability of a video card to process a TIN in ArcScene. The video card, the video card driver, the amount of RAM on the video card, the total amount of data being rendered in the scene, and many others. However, as an approximation, the numbers of nodes in a TIN that a video card can process are as follows:

128 MB on a video card = approximately 300,000 nodes

64 MB on a video card = approximately 200,000 nodes

32 MB on a video card = approximately 100,000 nodes

Start ArcScene with a surface visible.

1. Click the Fly tool.
2. Single-click the left mouse button. This is speed 1.
3. While flying, use the up arrow key to increase speed 1. Use the down arrow key to decrease speed 1. Speed 1 will be recalibrated.

Instructions provided describe how to clip a TIN with a polygon layer using 3D Analyst.

1. Add the TIN and the polygon layer to ArcMap or ArcScene.
2. Select 3D Analyst > Create/Modify TIN > Add Features to TIN.
3. Select the TIN as the Input TIN.
4. Check the polygon layer.
5. Use the following settings for the selected layer:

   Height source: <None>
   Triangluate As: hard clip
   Tag value field: <None>

6. Save changes into a new output TIN option and enter a name for the output TIN.

   The output TIN will not look identical to the input TIN along the boundary of the polygon layer. This is because the boundary of the polygon layer may intersect triangles in the TIN. The new triangles will need to be interpolated. This should only result in minor modifications and will not drastically change the surface of the TIN.

7. Click OK.

Below is a list of all common causes that may generate the error message:

"Operation Failed"

The ESRI articles below address the various causes, and provide a workaround when available. Please note that it may be necessary to log on to our support site before viewing some of these articles.

Codecs (compression-decompression) are used to encode images, video, and audio to a specific format such AVI or MOV. Windows has a standard set of codec settings, but machines will generally have several third party codecs installed from various software applications.

Codecs vary widely in implementation and version, even between different machines. A codec of the same name might work on a certain machine and fail on another.

Some codec settings appear to be more robust than others, for example Cinepak Codec by Radius or Intel Indeo Video R 3.2.

Cause
Some of the codec settings may not work properly because of several factors such as the inability to support 16-bit images or it may not support exporting to AVI format. Even if a codec is listed when exporting an animation in ArcScene, that codec may not be valid for exporting to video. Please see the codec manufacturers website for relevant information relating to a particular codec setting.

For example, the Microsoft RLE codec was made for MS Windows 95, a legacy system. A particular codec setting may not function properly if it does not support AVI or MOV formats.

Solution or Workaround
If certain codec settings are not allowing for the export of an AVI, the recommendation is to use one of the codecs that can complete the AVI export or alternatively, consider using QuickTime MOV export
