3D Analyst and Spatial Analyst are not included in ArcInfo. These are separate installations and require an additional license. If you are licensed for these extensions, you may need to check to see if they have been installed.  It looks like the extensions are installed since they appear in the extensions list. There are steps to registry the extension in this document: Using Extensions in ArcGIS You can check to see if they are installed by going to Windows Control Panel > Add or Remove Programs > select ArcGIS Desktop from the program list and click Change. For here you can see what features are installed. Adding additional installation features ... View more

Hi Helena, Dan is right, you will need to use the Plus tool.  This tool is found under the Spatial Analyst Toolbox > Math.  You can only add two raster at a time with the Plus tool.  You can however use the Raster Calculator (Spatial Analyst > Map Algebra) and create an expression to add all of the rasters.  -Timothy ...

I was able to see the same behavior by renaming a band in ArcCatalog 9.3.1 and then viewing in ArcCatalog 10.  It goes back to the original band name.  I also noticed the renaming a band in 10 remains the same in 9.3.1.  I wonder if it has something to do with how each version is reading the file. If you do not get any other responses, I would suggest that you contact Esri Support so that this issue can be looked into further. ... View more

Note sure if this will get you to your expectations, but open an edit session and select all of the features.  Then use the merge function from the editor menu.  This will take all of the feature and create a single multipatch feature.  If you then would like for them to be individual features you can use the Multipart to Singlepart tool. ...

Hi Yair, Yes, the editing functionality had changed a bit in ArcGIS 10.  The target editing layer is no longer on the toolbar.  You can now select the layer to edit from the Create Features window and then a construction tool.  Look at the following document for further detail:  A quick tour of editing There is also the option to switch back to 9.x edit environment.  It is described in the following blog: Setting the Edit and Snapping Environments in ArcGIS 10 to the Classic (9.x) Format -Timothy ...

Hi Mark, You can find the difference using the Spatial Analyst tools.  The Minus tool will allow you to subtract one raster from the other.  There is also an assortment of other raster evaluation tools as well within the Math toolset. -Timothy ... View more

Yes, I get the same error with those maps.  I did find the following KB Article: Error:  Could not open the specified file This seems to apply to map packages that were created in 10 sp1 but are being opened by 10 sp0.  I have service pack 1 installed so for me this fix does not apply. -Timothy ...

Hi! You will need to specify these values within your point feature class.  You will need to add the field into the attribute table and define the values.  Make sure you use the exact field name so that it can be recognized by the process. You can see the field names for each parameter that can be used in the following document: Using Viewshed and Observer Points for visibility analysis The follow steps comes from the 9.3 help: Using the ArcGIS Spatial Analyst toolbar to calculate Viewshed -Timothy ...

Hi Ben, Are you using the 3D Layer to Feature Class tool in ArcMap or ArcScene?  The tool uses the 3D layer properties and creates the multipatch.  In ArcMap there are no 3D properties, so the resulting multipatch would be flat.  You will need to run the tool in ArcScene with the 3D properties applied to the layer.
