  1. Hi, Yes, you will need to have ArcGIS 10 to do the volume calculation. In ArcGIS 10 there is a new toolset as part of 3D Analyst named 3D Features, in there you have different tools for 3D operations. The Add Z Information tool will allow you to calculate a volume on a multipatch. Gil
  2. You can set the grid on a data frame using the Set Layer As Map Grid tool available on the AHGW toolbar (). The tool lets you select the feature classes and the grid value attributes (). You can also set the grid in the data frame properties, but the tool automates this. Gil
  3. This is part of a separate post by Simon: "when i try to pull say one cross section into a new map im not able to use or set up a customized grid where the major and minor grid line shape files are able to create the grid, it automatically does this for me when i create the cross section in the fist instance. Is this likely to be an issue with my extensions or something."
  4. Hi, Regarding the first topic - i don't think the problem is because you are using 9.3. looks like the tool is not able to read values from the DEM raster. Make sure that the raster is projected in the same coordinate system as the section lines and outcrop polygons. Also make sure you are using an appropriate discretization distance. If you check both of these and are still having a problem, please send me the map + geodatabase + raster and i will take a look. Regarding the grid lines - i opened a separate post for this: http://aquaveo.invisionzone.com/index.php?showtopic=1335 Please feel fr
  5. Hi, Are you getting a line in the XS2D data frame, but it is flat? Not sure I understand the issue. If you can send some more details that will be helpful. A figure showing the result/error would be good. Thanks, Gil
  6. Hi, You need to first create a new feature class that is referenced in the XS2D Catalog table. The drop down list you refer to is created from the catalog table. There is a tool for this named Create XS2D Line Feature Class that is located in the XS2D Editor toolset. You can take a look at the tutorial named Creating 2D Cross Sections, look for the section named "Adding Data From Geologic Maps" it includes a detailed description of the process. Gil
  7. Hi Dan, Currently the tool will only process a cross section if it is within the extent of all rasters specified in the raster catalog. So the limit is the raster with the smallest extent. However you can "trick" the tool to process all cross sections by changing the selected features in the section line feature class and changing the clip/fill values in the GeoRasters raster catalog. Here is an example: We have 3 rasters where the top raster has a smaller extent than the two other rasteras shown in Figure 1. also notice there are 3 section lines and one of the section lines extends beyond the
  8. Hi Adam, All the tutorials are also available on the Arc Hydro Groundwater Learning Center: http://www.aquaveo.com/ahgw-learning So you don't need to get all the tutorials if you are interested only in a specific one. Gil
  9. When creating a new Arc Hydro Groundwater (AHGW) geodatabase using the GP tools users do not have control over the XY and Z domain extents. One of our users from Brazil has found a way to set the coordinate systems and still maintain control of setting the extent of the domain: Create a blank Arc Hydro Groundwater (AHGW) geodatabase with no spatial reference set. Using Arc Catalog define the spatial reference for the feature datasets - during the process of defining the spatial reference you can modify the Min and Max domain values (XY and Z) so the spatial reference can contain your 3D data.
  10. When creating 3D features using the Arc Hydro Groundwater tools it is important to define your coordinate systems correctly. A few common mistakes that lead to errors in applying the tools are: The vertical coordinate system is not defined. The vertical coordinate system is defined incorrectly. A few examples are: Tools creating 3D features require that your XY coordinate system is a projected coordinate system. The tools will not work with data defined in geographic coordinate systems as the vertical information cannot be defined in geographic coordinates. The vertical coordinate system un
  11. Arc Hydro Groundwater version 3.0 is now available for download from our website: http://www.aquaveo.com/archydro-groundwater The release includes some new tools (as well as the regular improvements and bug fixes): New Tools for Managing Unique ID's - Two new tools have been added for managing unique ID values in an Arc Hydro Groundwater geodatabase. BoreholeLog to Points - This is a new tool that allows you to create 3D points from the BoreholeLog table. The 3D point features can be used to interpolate to rasters for generating GeoSection or GeoVolume features. For a full list of the new
