  Home MineScape Contents Glossary Index How to use Stratmodel Loading drill hole data  MTDR0029.00193 Mincom Loading drill hole data Overview Stratmodel uses drill hole data stored in a design file. Drill holes may be storedonmultiplelayerswithinthedesignfile,butonlyonedesignfilecanbeused.Theadvantages of storing holes on different layers are many. For example, newdrilling which has not yet been totally validated can be entered to a new layer,checked for errors, then when error free, transferred to the main layer. Sincemodelling modules request a list of layers, subsetting of different data types ondifferent layers can be useful, for example, it would then be possible to modelonly cored holes, or only holes drilled after a certain date.The drill holes are stored as graphical objects. A graphical object is an elementwhichstoresateachvertex,notonlygraphicaldata,butalsonongraphicaldata.Objects are used extensively throughout Minescape. See: Minescape Data Types in the Minescape Customisation Guide  .  Manipulation of graphical objects is possible using MPL (Mincom ProgrammingLanguage)—site tailoring can therefore be performed. See: Minescape Customisation Guide However, the average user is not required to know these details, as commonlyused functions are provided as part of the system.Drill hole data may be loaded from ASCII data files or manually added throughMinescape. The maximum number of vertices for a drill hole is 500.  Home MineScape Contents Glossary Index How to use Stratmodel Loading drill hole data  MTDR0029.00194 Mincom Creating display definitions for schema units  Prior to loading the data, display definitions for surfaces and intervals in theprojectmustbedefined.Displaydefinitionscontrolthegraphicalattributesofthedata.Two sets of display definitions are created: 1. The first set is used for drill hole intervals and must be of the form: DH_<interval> 2. Thesecondsetisusedfordisplayofsurfacesandintervalsingraphicsoutput,principally sections, and must be of the form: INT_<interval>SURF_<interval>_ROOFSURF_<interval>_FLOORSURF_<horizon> If the first set (prefixed  DH_  ) does not exist, the second set (prefixed  INT_  ) isused in drill hole loading of intervals.A series of forms have been provided to make entry of the information easy.On these forms, the names of all intervals and surfaces must be entered, butonlychangesinattributesneedbeentered.Wherethereisablankentry,thelastvalueenteredisused.Forexample,iftheweightforallintervalsis Ninex  ,enteriton the first line only.The drill hole object is a line. As a surface is a single vertex in the object, eachsurface is displayed using a marker; whilst each interval is displayed as a linesegment, as it consists of two vertices in the object.For surfaces , the graphics attributes that can be set are:  Colour  Section line style(for graphics output only)  Section weight(for graphics output only)  Home MineScape Contents Glossary Index How to use Stratmodel Loading drill hole data  MTDR0029.00195 Mincom For intervals , the graphics attributes that can be set are:  Colour  Section line style  Section weight  Section fill pattern  Section pattern size  Drill hole line weightAny intervals or surfaces lacking a display definition are assigned the defaultattributes.The name of the schema must be supplied as the interval and surface namesare validated against the schema.  Home MineScape Contents Glossary Index How to use Stratmodel Loading drill hole data  MTDR0029.00196 Mincom Creating display definitions for surfaces Whenasurfacedefinitioniscreated,thename,colour,linestyleandweightthatapply to presentation in cross-section are defined.Any attributes not set will use the last valid attribute set. Note: If display definitions exist for any of the selected surfaces, the settings for these display definitions are displayed on this form.
