Name

This is the identifier that will have a version. This name displays in the drop-down list on the Slice toolbar.

Section by

Easting: Select this option to enter a specific Easting value (X value). There are two ways to enter the Easting value, you can enter it directly into the text box, or you can click Digitise to select a point from the viewing window. The resulting section has a constant Easting (X) value. You will be facing in an easterly direction when defining the section view.

Northing: Select this option to enter a specific Northing value (Y value). There are two ways to enter the Northing value, you can enter it directly into the text box, or you can click Digitise to select a point from the viewing window. The resulting section has a constant Northing (Y) value.

Level Select this option to enter a specific Level value (Z value). There are two ways to enter the Level value, you can enter it directly in the text box, or you can click Digitise to select a point from the viewing window. The resulting section has a constant Level (Z) value.

Points : Select this option to define the plane by digitising two points and specifying the dip. To locate a point precisely, use the Snap to Objects or Snap to Points modes on the Digitise toolbar. Points may be snapped onto underlays, such as block model slices or triangulations. If you use Indicate mode to select the points, then the points have the current default Z value.

Plane

Enter the distance that is moved each step when moving the section through space. To move the section through space, use the Slice Forward or Slice Backwards icons on the Slice toolbar. Alternatively, you can select the Align View With Current Slicing Plane button on the Slice toolbar and use the up and down arrows to move through space. The default value is 0.

Dip

If you choose to select your plane by either a line segment or 2 points, then you must indicate a dip. The dip is the angle of the section from horizontal. Valid dip angles are between -90 and 90.

Backwards width

The view of your section will include everything behind your section.

Forwards width

The view of your section will include everything in front of your section.

Use shadows

Select this check box to shadow the data that falls outside the section. The default value is 20.0. The following options are only available when the Use Shadows check box is enabled.

Backward/Forwards

Specify the width of data that will be shadowed. The backwards width and the forwards width do not have to be the same value.

Reverse Facing

Select the Reverse Facing option if you want to reverse the facing direction of the predefined sections.

Auto section

Use Auto Section to automatically generate a set of sections that will be stored in the grid.

Select plane by

Select from Level, Northing and Easting. The default value is Level.

Start

Enter the starting point for automatically generated planes.

End

Enter the endpoint for automatically generated planes.

Step

Enter the distance that is moved each step when moving the section through space. The default value is 1.

Append

Select this option to automatically generate sections depending on the options entered in Auto section.

Use Clipping Planes

You can specify that the section is symmetrical (the same distance forwards and backward), or asymmetrical (different distance forward and backward). The default value is 20.0.

Use Shadows

Select this check box to shadow the data that falls outside the section. The default value is 20.0. The following options are only available when the Use Shadows check box is enabled.

Backward/Forwards width

Specify the width of data that will be shadowed. The backwards width and the forwards width do not have to be the same value.

Auto name

Select this check box to add the identifier Name for the set of sections. If you do not select the Auto name check box, you will need to enter a name in order to save the set of specifications sections.

Direction

Use the Direction option to specify and incorporate the direction in the naming process. This does not change the direction the sections are made, only the naming of the numbers.

Lock / Unlock button

This button locks and unlocks a pivot point around which the Easting, Northing and Plan views will rotate.

For example, in the image below the red dot has been selected as the pivot point.  The section showing for the Easting view will be the dark green.  The section showing for the Northing will be the blue-green.  The section showing for the Plan view will be the top surface.  All sections have the pivot point in common.
