How to compute the volume of a nominated voxel property value(s)

Josh Knight — Thu, 17 Jul 2014 00:59:15 GMT

Once you have defined the voxel area/value range you wish to compute the volume for by
using the Threshold properties tab dialog in the Voxel Model Properties, you can view the
calculated volume of the defined area by click on the Model Info button located on the File
tab of the Voxel Model Properties.

Creating 3D PDF from Encom Discover PA 3D display

Josh Knight — Fri, 07 Oct 2011 03:09:00 GMT

The process of creating a 3D PDF from Encom PA is reasonably straight forward using Adobe Acrobat 3D v9.0. The steps are:

1. Open PA and load your data/session into the 3D window and then set up the display to how you want it to look in the output PDF.

2. Open Acrobat 3D and click Edit->Preferences. Click 3D Capture and make sure "Enable global 3D capture" is enabled.

3. In Acrobat 3D click File->Create 3D PDF->From 3D Capture. Change the settings to enable capture from Encom PA (you may need to restart Encom PA when you do this for the first time).

4. Then go back to Encom PA and press the Prnt Scrn key on the keyboard . Accept the default 3D conversion settings when they appear.

5. You should now have a 3D PDF.

Tips:

1. Some of the object types in Encom PA may not convert across correctly. Multiple EGB's often have issues where the textures are not displayed correctly or may obscure other parts of the 3D content.

2. Transparency almost always causes issues in the PDF so it is best to avoid it

3. You should turn off the 3D axis and 3D Compass in Encom PA – The 3D compass is located in the Tools>Options dialog under the View tab and the 3D Axis (if present) can be turned off from the workspace tree.

4. On 3D vectors you should turn off the "Cull back" property.

Is there a way to have the view extents or positions exactly the same for two 3D maps?

Josh Knight — Thu, 03 Dec 2009 03:15:19 GMT

This can be achieved by using the 3D View Manager (button in the Zoom toolbar). This allows you to save a 3D view in one of the displays and then you can apply this same view to the other 3D display.

To save a 3D view:
1. Make the first 3D display active and then click on the View Manager button in the toolbar.
2. Press the Add button in the 3D View Manager dialog that appears and the 3D view in the currently active 3D display will be recorded – you will need to call it something and enter a description (optional).

To apply a 3D view:
3. Close down the 3D View Manager dialog and then make the 2^nd 3D display window active.
4. Click on the View Manager button again to re-open this.
5. Highlight the saved view in the list of the 3D View Manager dialog and press the button for "Jump the view to selected list items view position" and the 3D display should update.

How can I display Section Grids in 3D?

Josh Knight — Fri, 09 Oct 2009 03:50:45 GMT

Note: Section Grids generated externally from Encom PA cannot be imported into PA for display.

After generating section grid files in PA using the Section Gridding utility (accessed from the Gridding menu), Encom PA can display the gridded data in profiles or as 3D located images. In 2D displays, Section Grids can be used with their line association such that the Line Iterator can be used to cycle through survey data.

1. Section Grids can be added to documents containing either Curve/Section Profiles or 2D Graphs via the normal menu Add Data>Section Grid method.
2. Once displayed as section profiles (but with grid properties) right mouse click on the Profile 1 or Graph 1 branch in the workspace tree and select the View in 3D option from the pop-up menu.
3. Edit the properties for the Section export to 3D dialog that appears and click the OK button to generate a located image (.EGB) file with associated images that have been geo-referenced. These images will be automatically loaded into a new 3D display window for integration with other datasets or else just visualised individually.

How can I view Conductivity Section Profiles in 3D?

Josh Knight — Fri, 09 Oct 2009 03:27:43 GMT

To view conductivity-depth sections in 3D:
1. View the data as a Section Profile display first.
2. Generate a located image series of the specified lines in the database. This series is generated by using the View in 3D pop-up menu option, accessed by right mouse clicking on the Profile 1 branch in the workspace tree. The output from this option is automatically opened into a new 3D display.

NOTE: Any editing of the section profiles (e.g. colour scale, colour table, Y axis range, etc) should be performed PRIOR to using the View in 3D option for these properties cannot be edited once displayed as a located image in 3D.

How do I connect the 3D Connexion Space Navigator controller to Encom PA?

Josh Knight — Fri, 15 May 2009 00:17:59 GMT

1) Install the 3D Connexion Space Navigator driver software, and upgrade to the latest version.

2) Connect the device via USB port

3) Open the Encom PA and select the Tools>Options menu, and go to the View tab. Select Enable 3D Connexion devices option.

4) Close and restart the 3D window.

How can I get the 3D Cursor Plane to bond to a chosen Located Image?

Josh Knight — Wed, 17 Oct 2007 04:01:36 GMT

To bond the 3D Cursor Plane to a displayed Located Image make sure that the "Select" icon (shaped like a grey arrow) in the workspace tree located to the right of the Located Image branch is selected. When you select this icon the grey arrow should turn into a black arrow indicating that this Image is now active.
Then select the Bond To Image button on the 3D Cursor Plane toolbar. The bounding box should turn into a red coloured box fitting closely to the located image. You should also be able to see the red cross-haris move over the Located Image.

How can I display CDI section groups in 3D more memory efficiently?

Josh Knight — Wed, 17 Oct 2007 03:13:50 GMT

Displaying multiple CDI sections in 3D can be very memory hungry, depending on tehe resolution of your input data. An alternative to displaying a section group or multiple sections in 3D is to batch print the CDI sections while displayed in a single Section Profile display and display the resultant Located Images of the sections in 3D.
To quickly create these located images select the File>Batch Hardcopy Wizard menu option while the section profile display (showing the gridded sections) is the active window. On page 2 of the Batch Hardcopy Wizard interface choose the hardcopy image to be "Located Image files on disk" and specify how many survey lines you want to be processed. This will result in 1 located image (.EGB) file and a series of images (.PNG, .JPG, etc) for each line you chose to batch print.
In a new 3D display window add a Located Image data object and load the .EGB file that was created during the printing process. Alternatively drag and drop the .EGB file from a Windows Explorer page into the 3D display window.
