• LogPlot typically creates a banner (continuous) print by creating multiple 8.5 x 11 pages which are chained together with no top or base margins.  That’s the key – you still get a multi-page log but the print occupies the full 11″ extent of the letter-sized paper.  This allows these individual pages to print with no breaks on a roll of paper.  Of course, you can choose a legal page size if you prefer (8.5 x 14) or tabloid (11 x 17) if the printer offers these.  But the key is the no-margin setting.
• Another option is to specify one very long, custom page length in the printer software to accommodate the entire log on the roll output.  While this is possible, it requires futzing with the page size for each log, which is a pain, AND both the printer and Logplot can run out of memory processing the content for such a large “page”.  I don’t recommend this method unless absolutely necessary.
• The paper size and the printable portion of that paper (all defined by the printer driver) is stored in the log design in LogPlot.  This is how LP knows how to fit the graphic log on the sheets at compile time.

All plotters offer marginless printing, but sometimes it’s tricky to know how to set this in the driver AND to have LogPlot understand it.  I recommend that users first read the help topic about setting the log’s page size in the Help:

LogPlot's Help Topic on Setting Your Page Size

The goal: to get the Printable Length of the printer’s “page” to equal the Page Length (e.g. no margins).

Example:  I go to the Windows Control Panel, Devices & Printers.  I right-click on my HP Designjet T520 and choose Printing Preferences.  Here is the window, set to Letter “sheets”, roll paper source, portrait orientation:

HP T520 Printing Preferences Window

I then click the Margins/Layout button to tell the driver that I want Oversize printing so that there will be no margins (contents equal to paper size).

HP T520 Margin Settings

I Apply these settings and close the printer driver window.

In LogPlot, when I go to my log design, choose File | Setup, and choose this printer name, my Printable Length matches my Page Length (top of window). This indicates LogPlot now understands the driver’s setting for no top/bottom margin. Yay!  I click the Set Default Size at the bottom so that my LogPlot page now equals the printer page.

LogPlot Page Setup Window

All printer/plotter drivers have a different setup; if you get stuck contact our tech support group.

Once you have the page setup in your log design, then compiling the continuous log in LogPlot is easy.  In the Compile window, click on the Header + Footer tab and check the Continuous Output option.  This tells the program to put the header at the top of the first page and the footer at the bottom of the last page, with none in between.  (You can actually disable headers/footers entirely if you like.)

One other comment:  If you have an existing continuous log that you need to repaginate for a new/different page length for a new device, follow these steps:

1. Open a new LogView window in LogPlot7 (File | New | LogView).
2.  Choose the File | Open with Page Dimensions menu option.
3. Select the LPT file you wish to repaginate and print.
4. You’ll see the Page Setup window shown above. Be sure the printer info in the upper  part of the window is set up correctly, then click on Set Default Size in the lower part.
5. Click OK. LogPlot will repaginate the continuous log for the new page settings.

I’ll describe here an easy way to pop one profile onto another – in this example overlaying a benzene profile on top of a stratigraphy profile.

1. Create your two profile diagrams using the same annotation settings and the same profile slice.  This assures that the profile panels will have the same coordinate range.  I find it helpful to arrange the two profile windows on my screen, one above the other, so that they are both accessible.

Arrange both profiles on your screen so they're both visible.

2. With the RockPlot Edit Arrow tool activated, click on the I-Data profile contours to select them. (Note the red selection handles in the panel corners in the upper image.) Type Ctrl+C to copy this layer into memory.

Click on the I-Data profile color contours to select that layer, and copy it to the clipboard.

3. Click in the Stratigraphy profile window and type Ctrl+V to paste the I-Data profile into this diagram.

Paste the I-Data panel onto the Stratigraphy profile

4. Double-click on the I-Data layer you just pasted into the combined diagram to adjust the minimum contour level and transparency, so that the stratigraphic layers will be visible in the background.

Adjust the minimum contour level and/or transparency.

5. Click OK to close the Colorfill Attributes window.

Now you can see the stratigraphic profile in the background.

6. If you like, you can copy /paste the I-Data color legend in to the combined diagram.  Use your mouse to resize/rearrange the legends as desired.

Combined Stratigraphy and Benzene Profiles

1. First, be sure you’re using a build of LogPlot7 that is 7.4.81.107 or newer.

2. Set up your PDF printer as the default printer in LogPlot, using the program’s File |  Setup command. (On some systems you may also need to set up the PDF printer as default in the Windows Control Panel before launching LogPlot.)

3. You can set up the page size for the printer as well.

Setting up the PDF Printer Page Size

4. Set up the PDF printer driver to NOT prompt for PDF file names, and set the output folder to the same folder where the data files reside. I’ve attached an example of what my Acrobat Professional screen looks like, though your version or your PDF printing software may be different. Note that this is an important step so that you won’t be prompted for each PDF output file name.

PDF Print Settings

5. Then, select the Log | Batch Compile menu option in LogPlot.

6. Click the Add button, and in the Batch Editor window define the name of the data file, the log design, scale, and other compile settings. Be sure Print is selected, and be sure the Save as LPT file is also selected and a name defined. (The PDF file name will be based on the LPT name you define here.)

7. Click OK when you’re done, and you’ll see this log’s items listed in the batch window.

LogPlot Batch Window

8. Repeat for additional files, though you might start with just a handful to get the hang of it and to be sure the PDF files are actually being created.

9. Save your batch at some point, using the Save button in the Batch Compile window. At a later date, you can use the Load button in this window to load an already-saved batch listing.

! Note: the BTC file that is created is an ASCII XML-type file. If it is easier for you to modify the BTC file directly to add other logs, you certainly may do so, just be careful about the XML syntax.

10. To run the batch, just click the Go button at the bottom of the Batch Compile window. LogPlot should load the selected DAT file, compile it into the selected LDFX file using the indicated settings, save the requested LPT file, and print to PDF, storing the PDF file in the requested folder.  It will repeat this process for each item listed in the batch.

11. If you want to append all of the PDF’s into a single file, you can use Adobe Acrobat’s File | Combine | Merge Files menu option.

1. Create your contour map in RockWorks without faulting turned on.

• Use the Utilities Map | Grid-Based Map if your XYZ data is entered into the Utilities datasheet.
• Use any of the Borehole Manager contour mapping options (Map | Borehole Locations for ground surface contours, Stratigraphy | Structural Elevations for stratigraphic structure maps, etc.) if your data is entered into the borehole database.

2. In the displayed map, use the Draw | Line Types | Polyline to draw a fault polyline on your map.  Double-click to terminate the polyline.  You can repeat this if you have multiple faults.

3. Choose the arrow-shaped Edit tool from the RockPlot2D toolbar, and click on the polyline you drew, to select it.  (If selected, you’ll see square icons on the vertices.)  If you have multiple polylines drawn, hold down the Shift key on your keyboard to click on the next polyline to select it as well.  Continue in this manner for as many polylines as you drew so that all are selected.

4. Right-click on any of the selected polylines in the map window and choose Save to Faults Table.

Save Fault Polyline to a "Faults Table"

Enter a name to assign to the Faults Table and click OK.  This will be saved to the project database.

5. Return to the options along the left side of the map window, and click on the Gridding Options button.  Here, turn on the Faulting option (which is available under Inverse-Distance).  Enter the “distance multiplier” (usually 10) and browse for the name of the Fault Table that you just created.

Gridding Options - Faulting settings

Click OK to close this window. Click on the Grid Name prompt and enter a new name for the faulted grid model (such as “Potosi_faulted.grd”).

6. Click Process to recreate the grid model and map, now applying faulting.

Faulted Contour Map

Here are three-dimensional views of these surfaces:

Unfaulted Surface in 3D

Faulted Surface in 3D

RockWorks applies faulting by creating an interpolation barrier on either side of the polyline(s) – as it’s interpolating a grid node, any control points on the other side of the fault are now considered to be 10 times further away than they actually are, thus having no influence on that node.

Lithology Model in RockPlot3D

This presents a challenge, then, for users who wish to view lithologic SURFACES as plan-view contour maps, or in 3D, or exported to CAD.

In RockPlot3D you can access the lithology model’s Options window and filter the display for the desired material type, or range of types. Here is the above model filtered to display the Soil voxels only.

Lithology Model Filtered for Soil Only

This can be exported to DXF, but note that you’ll be getting all of the blocks representing that material. (Shown here in black and white for contrast purposes.)

Lithology Model Soil Voxels Exported to DXF

If you need a surface rather than blocks, RockWorks also has tools which will fit a surface to the uppermost elevations or the lowermost elevations of a rock type in a lithology model. These are in the Lithology | Superface (Top) and Subface (Base) menus. Here is an example of the same soil lithotype extracted as a surface (upper elevations), and displayed in RockPlot3D and then exported to DXF.
