This module enables the user to perform miscellaneous tasks via MicroMODEL. Most of the conversion utilities that exist for moving data to and from other modeling software are located in this module. Also included are printing, plotting, and AutoCAD output utilities.

0.1 Change Size of MicroMODEL Window

This menu choice enables the user to change the default size of the standard MicroMODEL program dialog window. In some cases, especially under the newer windows operating systems, it may be necessary to adjust the width and height of the window in order to show the entire layout. Simply click on the choice, and update the width and height in units of pixels. The default values are shown, and it is not possible to make the window any smaller than the default size.

0.2 Select Different MicroMODEL Directory

This menu choice allows the user to quickly switch from the current MicroMODEL project directory to another project directory. A new project can also be started via this menu choice.

0.3 Set Default Project Folder

This menu choice allows the user to set the default parent folder for MicroMODEL project folders.

0.4 Screen Preview of Plot File

This menu choice allows the user to select any MicroMODEL plot file (.PLT) that has previously been generated and display it on the screen.

From here, the user can elect to generate a bitmap file copy of the plot, or print the plot on any currently available printer. The plot can be printed to fit, or can be printed at any scale the user desires. Also, the user may choose to convert the plot to an AutoCAD DXF format.

0.5 HP750C (HPGL/2) Hard Copy of Plot File

This menu choice is generally outdated, as it is easier in most cases to plot directly to an HP plotter via the newer windows drivers. The Screen Preview Program (choice 0.4) allows the user to print the current screen to any available plotter, either as "plot to fit", or to scale. However, if there is a need to actually generate old style HPGL/2 code, then this program is available.

0.6 AutoCAD DXF from MicroMODEL Plot

This menu choice allows the user to take any previously created MicroMODEL plot (*.PLT) and convert it to AutoCAD DXF format. The description of the answerset is entered in the top input field. The name of the plot file (e.g. CELL.PLT) is entered in the second input field. The Access Files button can be used to select the input file via the standard file dialog.

The name of the AutoCAD DXF output file is entered in the third field, or can be selected by pressing the "Access Files" button to use the standard file dialog.

If the plot file consists of multiple displays, such as from a sequence of bench grade block displays, then there are two options that can be used to subdivide the drawings within AutoCAD. Choice one allows you to take the DXF output file name as a root, and append a three digit sequence number to this root name. One DXF file will be generated for each drawing. For example, with this option, a MicroMODEL plot file containing ten separate drawings is going to be written to AutoCAD file "MMPLOT.DXF". In this case, there will actually be ten DXF files generated, one for each original drawing, named MMPLOT001.DXF, MMPLOT002.DXF, ..., MMPLOT010.DXF

The second way of handling multiple drawings in one MicroMODEL plot file is to place all of the drawings in a single DXF file. In this case, each drawing will be written to a separate DXF layer, and the layer name will be generated using the Root name which is entered plus a three digit sequence number. For example, with this second option, a MicroMODEL plot file containing ten separate drawings is going to be written to AutoCAD file "MMPLOT.DXF", with a layer root name of "LAYER". In this case, there will actually be ten DXF layers generated, one for each original drawing, named LAYER001, LAYER002, ..., LAYER10. All drawings will be written to the single DXF file, MMPLOT.DXF

For pen color assignment, there are three options. The first is to assign the pen number to each entity within the DXF file. The second option assigns pen numbers via the header table in the DXF file. For this second option, the MicroMODEL layer names MMPEN01, MMPEN02, etc. are mapped to a matching AutoCAD color. The third option is to assign pen colors via an AutoCAD script file. In this case, a file named (MM Output File Root Name).SCR is generated. This script file must be manually read by AutoCAD after the DXF file is imported.

If a title block is part of the plot, then the Plot Scale must be entered. This plot scale is used to adust the size of the title block properly when it is transferred to the DXF output.

Normally, MicroMODEL plan view output for rotated models is rotated back to true east and north when converting to DXF. If the user wishes to override this behaviour and maintain the rotated view, then the check box for this option should be checked.

The default AutoCAD layernames and pen color mapping can be changed via the two buttons at the bottom of the input dialog.

0.7 Print MicroMODEL Output

This menu choice allows the user to start up the MicroMODEL editor of choice, and view the contents of any previously created MicroMODEL program text output (*.PRN)

0.8 Set Text Editor for Print Output

This menu choice allows the user to redefine the editing program that is used when opening MicroMODEL printer output. For example, to switch to NOTEPAD, navigate to C:\WINDOWS\SYSTEM32\NOTEPAD.EXE and click OK.

0.9 Do Not Print Headers (Check/Uncheck)

When this Menu choice is checked, then any text output from MicroMODEL programs will have the header lines suppressed. Some MicroMODEL users prefer to leave out the header information to make it easier to import MicroMODEL information into other programs such as Excel or Word.

0.10 DXF Conversion Utilities

This Menu choice provides access to several functions allowing import or export from/to AutoCAD DXF format.

0.10.1 Topo Line Conversions

This choice allows the user to convert AutoCAD string data in the form of LINEs, POLYLINEs, or LWPOLYLINEs to MicroMODEL. A description of the run should be entered in the answerset name field. A check box can be selected to override the standard function of taking the Z attribute and storing it as the elevation, but in most cases, this option will not be used.

In rare cases, the needed data resides in the BLOCKS section of the DXF file, instead of in the ENTITIES section. To convert items that reside in the BLOCKS section, check the box "My data is in section BLOCKS (not ENTITIES)".

The user may opt to filter the data as it is being read in. For very dense data, this may be desirable. MicroMODEL will eliminate any "middle" points in a sequence of three points where the middle point is located less than or equal the filter tolerance distance from an imaginary line drawn between the two endpoints.

The user selects the name of the input DXF file by pressing the upper large button. The user selects the name of the output file (digitized MicroMODEL data file) via the lower large button.

After selecting the input/output file names, the user should press the "Scan DXF File" button. This will scan the DXF file, looking for instances of LINEs, POLYLINEs, and LWPOLYLINEs. It will list all AutoCAD layer names that contain these entities. Once these layer names are listed, the user must select which type of entity to convert, via the set of radio buttons located just below the output file selection button.

If there are layers listed which should NOT be converted, the checkbox for these layers should be unchecked.

Finally, press the "Convert DXF File (RUN)" button to convert the DXF file.

0.10.2 Triangulated Model Conversions

This choice allows the user to convert AutoCAD DXF 3DFACE data (wireframes) into various forms that are useable by MicroMODEL. The most common use of this program is to take a standard TIN model for a surface, in the form of AutoCAD 3DFACE entities, and convert the surface directly to a MicroMODEL topography surface (a.k.a. cone surface). In the top field, enter the description of this run.

The name of the DXF file to convert is entered by pressing the large button in the "Enter Name of AutoCAD DXF Input File" group box. The name of a standard MicroMODEL Binary Triangle Data File can be entered in the next group box down. A check box must be activated in order to actually create the file.

Five radio buttons are shown, and the user must select which Output Option to use with these buttons. The first choice will write the surface TIN triangles out to a MicroMODEL digitized file format. This first choice would be used if the user simply wants to get of view of the horizontal extent of the topo data which is available in the TIN file.

The second choice also converts the TIN data into a standard digitized file format, but in this case, the output file contains easting, northing, and elevation values for each 2-D grid centroid that falls within one of the TIN triangles. These values can then be used as input locations for 2-D surface modelling.

The third choice is the one most commonly used. This option takes the TIN data, and converts it directly to a standard MicroMODEL surface file. The file in which the surface information is stored is selected in the "2-D Surface Output Options" group box. Enter the name of the new surface, select which surface number to store the results in, and optionally elect to initialize the surface model values to missing before processing the TIN file. Note that if the OPD Sub-columns or OPD Sub-rows are greater than 1, then the user has the option of converting the TIN to an OPD gridded surface (P2xx) in addtion to the standard 2-D surface grid (T2xx).

The fourth choice allows the user to convert 3-D wireframe TINs into 3-D rock models. If this choice is selected, then the user must fill in the lookup table which assigns AutoCAD layer names to rock codes. The layer names in this table can be automatically filled in by pressing the "Scan DXF File" button. Once the layers are filled in, enter the rock code for each layer. If a particular layer should be skipped, then delete that layer name from the list. You do not need to move the entries up in the table to remove empty lines. The name of the intermediate work file which contains the rock coding information is selected via the push button just above the radio buttons.

If the user is only interested in creating a standard MicroMODEL Binary triangle data file, then the radio button "No additional output" should be selected. Binary triangle data can be processed by another MicroMODEL program to extract outlines of the wireframe at the midpoint of each bench in the MicroMODEL project.

If, for some reason, the original DXF file was generated in a coordinate system with a different origin point, the user may elect to add an X and Y offset to the data, to get it to match the current coordinate system.

0.10.3 Create GRIDIN file from Intermediate Data

This choice allows the user to convert an intermediate data file coming from the Triangulated Model Conversions Program, and create a standard 3-D model input file. The 3-D model input file is used to update the MicroMODEL 3-D Rock model.

Enter a description of the run at the top of the dialog. Then, enter the names of the Sorted Column/Row/Elev/Rock file. This is the name of the file that was specified in 0.9.2. The name of the output file is then entered. This is the file that will be used as input to the MicroMODEL program that reads 3-D grid data. A name for the error listing file should also be entered. After running the conversion, check the error listing file to be sure there were no errors detected.

Refer to the File Manager, choice 6 (Import from file to MicroMODEL Grid or Block Model), to see how to import the 3-D grid data.

0.10.4 Create POLY.RKP from Binary Triangle Output

This choice allows the user to "slice" a wireframe that has been converted to the standard MicroMODEL internal format (Binary Triangle). The slices can then be displayed by the "Plot digitized geology data in Plan View" program.

Enter a description of this run at the top of the screen. The starting and stopping levels to be extracted are then selected. Select the name of the binary triangle file, and the name of the digitized rock in plan view file (normally, POLY.RKP).

This program will attempt to join all of the segments that are generated by slicing the wireframe, but in many cases, this will not be possible. The user SHOULD NOT ATTEMPT TO USE a poly.rkp style file generated with this program to try and assign rock codes without first cleaning up the outlines via the PolyMap program. Besides, there is a more direct way (see 0.9.3).

0.10.5 Create POLY.RKS from DXF Section

This choice allows the user to convert gelogic outlines stored in AutoCAD DXF format into the standard MicroMODEL format for storing digitized geologic data in section.

0.10.6 Create POLY.RKP from DXF Plan

This choice allows the user to convert gelogic outlines stored in AutoCAD DXF format into the standard MicroMODEL format for storing digitized geologic data in plan.

0.10.7 Convert POLY.CNT or POLY.PIT to DXF

This choice allows the user to convert a digitzed topography or digitized pit file to AutoCAD DXF format.

0.10.8 Trim DXF Entities In/Out of Boundary

This choice allows the user to take line, polyline, or lwpolyline entries in an AutoCAD DXF file and trim them according to a polygon boundary. The user may opt to select a subset of the layers that are in the DXF file, as well as choose which entity types are converted. Line segments that fall within the polygon boundary can either be kept or rejected.

This is a very useful tool for generating end of period maps involving pit designs and dumps

The boundary file is the same format as a reserve outline or no-mine boundary. The first line is assumed to be a header and is ignored. The remaining lines all consist of easting and northing pairs that represent the boundary. A final blank line at the end signifies the end of the boundary. A POLY.CNT style file can be used as a boundary, provided that it contains a single polyline. The first line, which would be " 'elevation' 0 0 'npt' " is ignored.

The user supplies the name of the boundary file, the name of the AutoCAD DXF input file, and the name of the AutoCAD DXF output file. Two radio buttons are used to choose whether to keep everything inside or outside the boundary.

The polylines can be filtered, if desired, by applying a simple polyline filter with a given tolerance factor. The factor should normally be on the order of 0.5 feet or less and should only be used in preparing a final report drawing where small differences caused by the application of the filter won't be noticed.

The button "Scan DXF File" can be used to find all of the entities in the DXF file that are "LINE", "POLYLINE", or "LWPOLYLINE", and the layers found for each entity type. Any or all of the entity types and layers can be converted in a single run. The trimmed version of the entity is written to the same layer name in the output DXF file as the one in which it resided in the input file.

0.11 GEMCOM (tm) Conversion Utilities

Convert Drillhole Data to GEMS Format

This choice allows the user to export the current MicroMODEL drillhole data base to a plain text format which is useable by the GEMS software. Enter a description of the run at the top of the dialog.

There are three separate output files from this program. The collar file contains the drillhole name, easting, northing, elevation, azimuth, dip, number of surveys, and depth. The assay file contains the drillhole hame, from, to, rock code, and assay values. The survey file contains the drillhole name, from, to, azimuth, and dip.

If drillhole class limits are in effect, then only those holes that are part of the currently selected class or classes will be displayed.

If drillhole class limits are in effect, then only those holes that are part of the currently selected class or classes will be exported to the output files.

Drillhole class limits are set in a separate screen. If no limits are in effect, then the text "USE ALL DRILLHOLES" appears next to the answerset name field in black letters. If limits are in effect, then the classes that are included are listed next to the answerset name field in red letters. For example, if input is limited to classes 1 and 3, then this text will read "DH LIMITED TO 1,3".

0.12 MEDSYSTEM (tm) Conversion Utilities

Transfer M101V1 Model Parameters

This choice allows the user to extract project origin and size information from an M101V1 printout. WARNING: the program overwrites the current MicroMODEL limits with those stored in the M101V1 printout. This choice should be used as part of the following sequence: (1) Create a new MicroMODEL project folder/directory. (2) Start up MicroMODEL, choose "new project", and navigate to the new folder. (3) Run this program choice to fill-in the model parameters listed in the MEDSYSTEM printout to the current MicroMODEL project.

Convert File 15 Labels to MicroMODEL

This choice allows the user to extract information from a MEDSYSTEM File 15 (3-D block model) an place it in MicroMODEL 3-D grade models.

Convert VBM to/from MicroMODEL

This choice allows the user to export information to or from a MEDSYSTEM VBM file.

0.13 Surface Generation Utilities

2-D Surface Grid from 3-D topo

This choice allows the user to take a 3-D topography percentage model and convert it to a standard MicroMODEL surface grid (cone surface). For example, it is standard practice in MEDSYSTEM (tm) to store a TOPO percent in each 3-D block. If this value is 100, then the entire block is below surface. If this value is between 1 and 99, then only a portion of the block is below surface. If this value is 0, then the block is totally above the surface. The program simply scans each vertical stack of blocks from the bottom, until it finds the last TOPO percent that is non-zero. The 2-D topo grid elevation is then calculated, based on the fraction of the block that is below surface. For example, if the highest 20 foot high block with non-zero TOPO is found on a level with base elevation of 2000, and the TOPO percent is 75, then the 2-D grid elevation for that cell will be set to 2000 + (75/100)*20, or 2015 feet.

0.14 Map Info (tm) MIF Conversion

This choice allows the user to convert a Mapinfo (tm) MIF file to MicroMODEL. The Mapinfo outlines can come from E/W sections, N/S sections, or plan view. The contents of the file are converted to either MicroMODEL digitized section information (POLY.RKS), or digitized plan view information (POLY.RKP).

0.15 Cleanup/Sort Answer File Responses

This choice allows the user to open up any standard response file (*.ANS) for MicroMODEL, and change the order of the reponses, delete one or more responses, or change the description of one or more responses. The order of the responses can be changed by moving answers up or down, or to the top or bottom of the list of responses. It is a handy tool to use when "cleaning up" a project to remove unused responses, or to make batch files that are better organized. For example, the user can synchronize sets of answers for the 3-D grade presort and 3-D grade modeling programs.

Simply select an answer file (it must have at least TWO responses). Then sort, delete, or rename responses. When finished, be sure and save the file. Refer to Volume II - File Organization Tables for a listing of the name of the response file that is used for each MicroMODEL program.

0.16 Import MicroMODEL License (Register)

This choice allows the user to register a copy of MicroMODEL. Download the license file provided by RKMA to your computer. Then, select this choice and navigate to the folder where the license has been stored. Click on the license file name.

0.17 Run MicroMODEL in Batch Mode

This choice allows the user to run MicroMODEL in batch mode. MicroMODEL can also be run in batch mode from the command line.

The user chooses the name of the batch processing file to execute, along with the name of the batch printout file.

0.18 Create Full Template File Each Run

If this choice is checked, then anytime a program is run in MicroMODEL, a full template file will be generated. This template file can then be reused or modified in a batch run. The name of the template file will consist of the program name (same as the name which preceeds .ANS in the answerset name) followed by a three digit number which is the answer set number with leading zeros. For example, the automatically generated template file name for running the drillhole section program (SECT) using the 3rd answerset will be SECT_003.TPL

If you are unsure of which batch parameter to change when running MicroMODEL in batch mode, a simple way of determining the parameter is to run the program two times. Run it the first time, and save the automatically generated template file information to a new file (by copying with Windows Explorer). Then, run it a second time, but change the specific item you are interested in. Bring up the first template file and second template file in an editor which lets you compare the two files. Find the one place where these files are different. This should be the line where your parameter of interest is being set.

0.19 Use Minimum Curve Method for Desurveying

It is suggested that the user leave this choice unchecked. When unchecked, a simple tangential method is used to desurvey the drillholes. The simple tangential method has been the standard desurveying method used by MicroMODEL since its inception in the early 1980's. Some industry pundits believe that the minimum curve method is a more accurate way of desurveying.

The minimum curve method will display drillholes as gently curving lines, rather than as a collection of straight segments which change direction at each downhole survey point. Tests show that there is normally very little difference between the two methods, unless there are severe directional changes in the drillholes.

0.20 Disable Title Block Option

If you do not need to display the standard title block with your plot, then check this option. Checking the option will bypass the title block prompt program, and it will also cause the plot display program to bypass the prompt for plotting scale. In all, three mouse clicks are avoided.

To reinstate title block plotting, uncheck this box. Note that if you creat a plot file pair (*.PLT,*.SCL) with the title block option enabled, then the title block information is actually stored in the plot file. If you turn title block plotting off, and then use the "Screen Preview of Plot File" to display this file, then you will see the title block as part of the display. You need to rerun the plot with the "Disable Title Block Option" checked in order to remove the title block informtion from the plot file.

0.21 Exit

Use this choice to exit MicroMODEL. The user can also click on the "close window" X to end a MicroMODEL session.
