Borehole Geologic Columns

The Geologic Columns dialog allows you to generate detailed labeled columns representing borehole data.

Keyboard Command: GeoBorCol

Procedure:

1. Specify the 'Default Offset' desired at the bottom of the dialog.
2. Select a borehole in upper left to add to the sequence.
3. Choose the fields to label in the upper right list.
4. Choose the Add to List button to add it.
5. Repeat steps 2 thru 5 as desired.
6. Optionally choose the Save icon in the sequence section to save for later recall.
7. Specify additional parameters in the bottom section.
8. Choose OK to begin processing.

Notes:

• Borehole Columns are built as block definitions prefixed with "BORE_". You can use AutoCAD's BEDIT command to make modifications to the inserts.

Dialog Sections Detailed:

• Holes Found: This list contains the HOL files found in the search paths.
  • Alignment: Allows you to select a polyline to use for determining the offsets (which is the borehole stations along the polyline).
  • Add to List: Adds the selected boreholes to the generate sequence list.
  • Select: Allows you to select the boreholes in the drawing which selects them in the list.
  • Select All: Selects all boreholes in the list.
  • Clear All: Clears all selected boreholes in the list.
• Label Fields: This list contains all the fields found in the found holes.
  • Select All: Selects all fields.
  • Clear All: Clears all selected fields.
  • Move Up: Moves the selected row up in the list.
  • Move Down: Moves the selected row down in the list.
• Generate Sequence: The spreadsheet and the control icons above it are used to establish the sequence.
  • New: Clears the grid to begin a new sequence.
  • Open: Prompts for a CSS (Column Sequence) file.
  • Save: Saves the contents of the grid to a CSS file.
  • Print: Prints the contents of the grid.
  • Delete Row: Deletes the currently selected row.
  • Move Row Up: Moves the currently selected row up one position.
  • Move Row Down: Moves the currently selected row down one position.
  • Sort: Sorts the contents of the grid.
• Specifications:
  • Insertion N/E: Enter the coordinates or use the pointer button to pick a base location in the drawing. If you turn on the Insert At Core toggle, you can use these two fields to specify the X/Y offsets relative to the borehole location.
  • Layer: Enter a layer name or choose an existing layer from the drop down list.
  • Scale Factor: Enter the insertion scale desired for the bore blocks.
  • Elev Bar: Turn on the toggle if you want to add a elevation bar on the left of the core.
  • Label Size: Enter a size for the core name and elevation label. The size is multiplied by the scale to determine the actual label size.
  • Default Offset: For single holes, enter the (x) offset from 0, for multiple holes, enter the distance between holes.
  • Interval: Enter the distance in feet for the interval to label the elevation bar.
  • Min Thick: If labeling of thin strata members cause a undesired overlap in description labels, enter a minimum thickness that the strata item must be, in order to be labeled.
  • Label Font: Optionally enter a font name to use. Otherwise the current style is used.
  • Text Size: Enter a size (in drawing units) for the core elevation bar labels. The size is multiplied by the scale to determine the actual label size.
  • Core Width: Enter a width (in drawing units), to determine the width of the corehole in the section plot. The size is multiplied by the scale to determine the resulting core width.
  • Layer: Enter a layer name or choose an existing layer from the drop down list.
