BEXPORT

Use this to export a block model to an ASCII file. The blocks to export can be selected by specifying selection parameters.

Usage:

bexport [options] <model>

<> indicates a mandatory switch.
[ ] indicates an optional switch

Where:

Option

Description

[options]

The [options] for this executable are:

-i <delimiter>	Delimiter used to separate fields. Use 'C' for ','. Use 'T' for tabulator.
-o <file>	Redirect output to a nominated file. You will need to include a file extension, for example '.asc'.
-k <file>	Append output to a nominated file. You will need to include a file extension, for example '.asc'.
-v <variable> [value]	Mask with variable.
-t <triangulation>	Bounding triangulation.
-n <top surface>	Top bounding surface triangulation.
-u <lower surface>	Lower bounding surface triangulation.
-B <triangulation>	Use a single bounding surface.
-Z	Project down the Z-axis, i.e. select the blocks that fall below the nominated surface. If the -Z switch is omitted, then all blocks that fall above the nominated surface will be selected instead. Note: This switch can only be used when a single bounding surface has been specified.
-O	Select blocks outside the solid only.
-bm <xl, xt, yl, yt, zl, zt>	Define the bounding extents using block model co-ordinates. When using this switch, you will need to specify the minimum and maximum X, Y and Z co-ordinates.
-bw <xl, xt, yl, yt, zl, zt>	Define the bounding extents using real world co-ordinates. When using this switch, you will need to specify the minimum and maximum X, Y and Z co-ordinates.
-s <mx, my, mz>	Sub-block dimensions.
-p <a, b, c, d>	Include planed blocks.
-C <condition>	Use conditional expression.
-r <offset>	Provide a plane offset buffer.
-X	Use proportional volumes against solid.
-e	Include block extents.
-J	Include corner offsets. This information will be reported after the block volume.
-I	Include block IDs.
-V	Include block volumes.
-c	Include block centroids.
-L	Include block lengths.
-E	Include model extent.
-W	Export block centroids as real-world co-ordinates.
-h <width.decimals>	Format in which to print header.
-P <variable>	Print a nominated block variable.
-f <width.decimals>	Format in which to print the nominated block variable.
-A	Print all block variables.
-N	Initialise name variables with strings.
-H	Include a header line, i.e. column names, in the resulting export file.

<model>

Refers to the name of the block model containing the blocks to export.

Example:

bexport -o bexport_example.txt -A example.bmf

N ote The following warning messages displays if any triangulations have small area faces or coincident points.

Note triangulation <tfi> has one or more small area faces. Note triangulation <tfi> has two or more coincident points.

In most cases the program will work correctly on triangulations with small faces or coincident points. However, if the triangulation contains a topological inconsistency, it is necessary to run trisnapon the triangulation to remove coincident points. Also, all triangulations should be checked for consistency and stability with the Model > Triangle Utility > Check option.
