What is a Current Object?

When data is loaded into memory in Studio 3, an object is created. Studio 3 supports five types of 3Dobjects; points. strings, drillholes, wireframes and block models, and each file loaded will create aseparate object of one of these types.

When there are several 3D objects of one type, e.g. strings, only one of them can be the current object ofthat type.

Why is a current object necessary?

The current object is the one that will be changed if data is edited in memory. For instance, if there areseveral string objects in memory and a new string is digitized, it is important to know which of theobjects it will be incorporated into or whether it will be a new, separate object.

It is important to remember that an 'object' is effectively a data container, and can contain one, ormultiple instances of certain types of objects. For example, three separate string entities can becontained within a single object, or represented as 3 separate objects containing a string each. Objectswill only ever contain data of a type that is relevant to the object type.

Which is the current object and how can it be changed?

There are two ways of identifying the current object:

In the Loaded Data control bar where the name of the current object of each type will beemboldened.

In the Current Objects tool bar where the current object of each type is named.

When more than one object of a type is loaded, the current object can be changed by double-clicking thename of the desired current object in the Loaded Data control bar. This object name will be emboldenedand the erstwhile current object name will change to a normal font.

The Current Objects tool bar can also be used to change the current object. Use the object type pull-down to select the object type of interest: points, strings, drillholes, wireframes or block models, thenuse the second pull-down to select the object of that type which is to be current.

The Current Objecttoolbar has two drop-down lists. The first allows you to select the object type:points, string, wireframe etc. whilst the second lets you choose which of the objects of the selected typeyou wish to modify.

In addition to these boxes there are buttons for creating a new object, saving to the current object anddeleting the current object.

Current objects and the Loaded Data control bar

Current objects are displayed in bold text in the Loaded Datacontrol bar. In the following screen shottwo block models and two wireframes have been loaded, but only one of each is current. Double-clickan object's name to change its status to "current object".

How are current objects Managed?

Once an object has been defined as 'current' it is the focus of all subsequent operations that relate to itsdata type; for example, when adding a new wireframe triangle, the data will be added to the currentobject. Similarly, when digitizing, newly-defined string data will be added to the current string object.

Every data type (wireframe, string, drillhole, block model, points) will have a current objectassociated with it.

If current objects are unloaded from memory (and this action is confirmed), the next object in thelist (of the same data type) will automatically be assigned as the current object.

Overlays of current objects can be rendered invisible (using the Format Displaydialog, or bydisabling their view in the Sheetscontrol bar, for example). If you try to add data to a 'hidden'current object, data will be added in the form of a new independent data object, which will also beset to the new current data.

You can set any object to the current one by double-clicking it in the Loaded Datacontrol bar, orby selecting it in the Current Objecttoolbar's drop-down list (select the data type, then theobject). Note that if an object is hidden, you will not be able to set it as the current object usingeither method.

If no current object is set, one will automatically be created if subsequent operations require one.Digitizing a string in a new project, for example, will automatically create a "New Strings" objectand default overlay (sheet). Similarly, creating a DTM will create a new wireframe object if noneis currently set.

You can create a new current object at any time using the Current Objecttoolbar.

Archiving Data

Background

Studio 3 projects supports a data model that maintains links to data in component tables such that thedata is always effectively 'current'. This is ideal for day-to-day working but sometimes there is a need totake a permanent snapshot of the situation at a specific point in time. It is also desirable, sometimes, tobe able to save all the data inside the project file to facilitate shipping between systems.

The Archiveoption enables this. An archived document contains all the data and formatting necessaryto recreate exactly the snapshot scenario.

To archive a document, chooseFile | Archivethen give the archived file a name and browse for alocation when prompted to do so.

What does archiving do?

Normally, data is saved asfilesto a disk which can be either local or remote. The Project File managesall this data and will invoke the necessary drivers and controls to load the data and display it when theproject is next started.

The archiving mechanism only uses data loaded into memory (thus making them 'objects') at the time ofarchiving. It breaks away from the normal mechanism by saving all the data inside the Project File itself

such that it becomes a repository for everything in memory.

An archive is ostensibly an ordinary project file (with the standard .dmproj extension), but there are oneor two minor distinctions:

When a project is archived, unlike a normal "Save as..." operation, the parent project remains openfor editing not the saved (archived) project.

The archive can be many times larger than a normal Project File as it contains all the data.

Selective Archiving

The Data Object Managerlists all data currently loaded into memory along with the data source foreach, which can be a file on disk or the Project File itself.

Sharing projects

If your group uses a Local Area Network (LAN) you can share documents over the network. WithWindows 98, ME, NT, 2000 and XP systems you will be able to access documents over the network inexactly the same way as the documents on your local hard disk.

Opening a project over a network

The network directory will be shown in the Look in box on the Open dialog. You can select thenetworked file and open it.

Copying and moving documents

To understand the situations in which a document can be copied or moved to another location for use byother Studio 3 users, you first need to understand the following concepts:

How does the program locate data source files?

The location of the external data files referenced by the document are stored as both absolute andrelative addresses.

1. For example, if the full path name of the document is:c:\My Projects\Thunder Gulch\Thunder Gulch.dhx

2. and references a data source file stored at:c:\My Data\Thunder Gulch\tg_collars.txt

3. when the document is opened, the program first looks for the file using the absolute address:c:\My Data\Thunder Gulch\tg_collars.txt

4. and if the file cannot be located, the program then looks for the file using the relative address:

..\..\My Data\Thunder Gulch\tg_collars.txt

Summary

Accessing Projects over a network

While you have a document opened from a network, others who try to open the document are

notified that the document is not available.

Copying or moving the document to a different directory on thesame disk

If you copy or move the document to a new directory on the same computer, the program will always beable to find the data source files using the absolute address.

Copying or moving the document to a different disk on the samecomputer

If you copy or move the document from the c: drive to say the d: drive, the program will always be able

to find the data source files using the absolute address.

Copying or moving the document to a different computer on thesame network

If the data source files and the document were originally located on different computers on the samenetwork, the absolute address stored in the document will include the network address. So when thedocument is copied or moved around the network, the program will always be able to locate the datasource file using the absolute address.

On the other hand, if the data source file and the document were both originally located on the samecomputer, the absolute address is local to that computer. Hence if the document is copied or movedacross the network, the program will be unable to locate the file using either the absolute or the relativeaddress and will prompt you to locate the file again by displaying the Open dialog. You can howeveropen the document across the network and then save it to the local disk using the Save As command.The copied document will now contain the network locations of all data source files.

Copying or moving the document to a different computer off thenetwork

If you copy or move the document to a different computer off the network, the data source files mustalso be moved to the same relative address.

Moving a data source file to another location or name

If you move a data source file to a different directory or a different disk or a different computer on or offthe network, or rename the file, the program will be unable to locate the file using either the absolute orthe relative addresses and will prompt you to locate the file again by displaying the Open dialog.

Different Different Different Same OK if data source is on different computer, but not foundif on the same computer as originally located.

Custom legends

If you are using custom patterns and textures in your legends, Studio 3 installations on other computerswill need to be updated with these custom bitmaps.

Studio 3 Compatibility

Studio 3 comes complete with a comprehensive set of data source drivers which enable it to import

from, and export to, most major data formats being used by the mining industry, and elsewhere.

Data Source Drivers

Data source drivers (DSDs) are used for importing data to, or exporting it from, a program. The driverssupport a variety of data types including CAD files, RDBMS tables, spreadsheets and a selection of thirdparty data formats.

For more information on Data Source Drivers see Data Source Drivers

Summary of Data Types

Data type A: Datamine file in the project folderIn general, these are working files such as strings and wireframes, which do not need to be stored in acentral database. Studio 3 can run using only this type of data.

To improve performance, temporary files created during batch processing, or data manipulation, mayalso fall into this category.

users. Having a single reference point avoids the need to manage multiple copies of a key file andensures all users are always working with the same data.

Example of use

A resource model has been created, and is being updated, by geologists also it also needs to be accessed by the mine

engineers for planning purposes.

Data Type B Usage Table

*Macros can use files that are not in the current directory by running the script command SetNamefForMacro()function.

Data type C: Imported Data cached as aDatamine file

Cached files are used to access data from a third party source and store it in the project folder, as aDatamine file, for further processing. The key characteristic of this data type is that a link is maintainedto the external source so that the Datamine file can be refreshed easily whenever a latest version of thesource data is required. This data type is used for mine data stored in a third party format but whichneeds to be processed using Studio 3.

Examples of use

A large geological block model (many megabytes) is stored in a corporate geological modelingsystem. Datamine will recognize that the data are stored externally, in the corporate database, butit will optimize its performance by accessing the data using its own formats.

Drilling data (Collars, Surveys, and Samples files) are usually stored in an external database suchas SQL Server or Microsoft ACCESS. The data are often imported into Studio for furthervalidation, processing and modeling. As with geological block models it is not always desirable to

get the very latest data if it is changing frequently and represents work in progress.

Data type D: Automatically Imported Data

This memory-based data type is used to access data from a third party source and load it into the DesignWindow. In other words, the data are loaded into memory but are not stored as a Datamine file. A link tothe external source is maintained so that the data can be reloaded easily into the Design Window whenneeded. This is for data that are not processed directly but are needed for display or reference purposes

when working with other data.

Example of use

When surveyed underground development wireframes (drives and cross-cuts) are imported for usein a ring design, they are only needed as a reference. The wireframes themselves will not bechanged.

Note:This category is only for data which can be saved to a Datamine file if needed.

Data Type D Usage Table

Data type E: Archived Data

These data are actually stored within the Studio Project file rather than in a linked external source. The

archived data type is useful for saving a snapshot of the data (and any settings) used at a particular time.

Example of use

A set of plots can be be saved as archived data to be printed-out at a later date.

Data Type E Usage Table

Data type F: Other

Other data includes file-based data which are not stored in the Datamine format such as fields andrecords. The most common examples would be macros and scripts which are used to record and runuser-defined sequences of Datamine commands. Both macros and scripts are stored as lists of

Examples of use

Bitmap files, representing Company logos, to be added to title boxes on plotted plans and sectionswould also fall into this category.

A bitmap file representing seismic survey data could be loaded as geo-referenced data into theDesign Window, or it could be loaded as a texture, mapped onto a 3D surface in the InTouchVirtual Reality view.

Attribute Manager

An explanation of fields and properties




24/30

Attributesare an important component of Studio 3 data; they can control the visual appearance of aloaded file or can be stored 'silently' within any data object as a means of storing data values. Thesevalues can be integers or strings.

The Attribute Managerallows you to add and remove attributes for any data object in memory. It canalso be used to create attributetemplatesto specify default user-columns to be assigned to an object of aparticular type upon creation. This facility has the potential to save you a lot of time by effectively

automating the manual task of preparing data objects in a standard fashion.

Please note that, for the sake of this help topic, the terms "property", "column", "field" and "attribute"are synonymous - they are the distinct data descriptions of individual components of an object inmemory. The expression "value", however, is distinct; this specifically describes the integer or stringthat a particular attribute contains.

When defining attributes for a particular data type, you can use an existing object of that type as astarting point, or you can create a new template from nothing.

The Attribute Managercan be used to define templates or in situ fields for any "user" attribute. A user

attribute is a value that is not strictly required by a particular data object type (wireframe, string etc.) butcan be used to store values that are relevant to it. User attributes are, by definition, not essential forStudio 3 to recognize a particular data table as a specific visual type, but they may be critical to theoverall process that the data flows through from inception to completion.

Attribute Manager Capabilities

Using the Attribute Manageryou can:

Create and manage templates that will be adopted by all new objects created (on a type-by-typebasis).

Define custom attributes and apply them to existing objects.

Disable or enable existing attributes for any object in memory.

Globally enable or disable attributes for all objects in memory.

Selectively view or hide objects of a specific data type from the attribute table.

Apply a predefined template to any existing object of a given type.

However, you will notbe able to:

Disable or edit mandatory fields that define a data type (essential fields, such as LSTYLE forstrings, for example).

Create a template that will be adopted by a non-visual table (only wireframe, block model, point,string and drillhole attributes can be controlled using templates).

Create a template to be used when importing non-Datamine files (fields present in the externaldata set will always be honoured).




25/30

Change the basic definition of an existing attribute (although you can define new ones, or viewexisting definitions without editing them).

Attribute Manager Layout

The Attribute Manageris divided into two distinct areas; the top half of the screen indicates the statusof objects in memory (with respect to their attributes) and the lower half contains information about any

templates that may be set up for specific data types.

Enabling and Disabling Attributes for Objects in Memory

The Object Tablecan be used to manipulate the attributes of objects in memory (but only with regards towhether those attributes are shown or not - you will not be able to edit the definitions of those attributes- it is not possible, say, to change a string attribute to a numeric attribute).

You can change the status of an attribute (to either 'on' or 'off') using any of the following methods:

Double-clicking a table cell

Highlighting a table cell and pressing the bar

Right-clicking a highlighted cell and selecting either Set Selection Onor Set Selection Off

You can also set all attributes on or off for a given object by right-clicking one of the vertical table cells(those representing an object description) and selecting either the Set All On or Set All Offoptions.




26/30

One final option allows you to globally set an attribute to be active or inactive for all objects in theObject Table(at least, those that are currently displayed - see "Filtering the Attribute Manager", below).To do this, you will need to right-click the horizontal table columns (those describing the attributes) andselecting the Set All Onor Set All Offoptions

The basic procedure for using the Attribute Managerdepends on what you want to achieve. Thefollowing information represents a step-by-step guide to some common tasks that can be performed.

Understanding Attribute Templates

Attribute Templates serve two basic purposes:

Templates can be used to define the default fields for all new objects of a specified type that arecreated in memory.

Templates can be used to modify the current attributes stored by objects already existing inmemory.

In either case, template creation is performed in advance using the same method (described in the step-by-step procedures below). Once a template has been created, it can be assigned to any data type.Remember that the essential attributes required by an object type (the 'mandatory' fields) will always begenerated; it is the template that dictates the additional, optional attributes that you may wish to store.

For example, if part of your process requires a CUEQ grade to store copper equivalent grade values

Be cautious when enabling and disabling attributes.If an attribute is disabled, the contents ofthat data column will be lost from the object in memory. To prevent this situation, you should savethe object(s) in memory to a physical file before editing - that way, you can recall the previousstate of the object if required.

Reintroducing an attribute with the same name as one previously deleted will not re-implementany data values that were set beforehand.




27/30

generated by Studio 3 evaluation routines and calculations, a template could be created and assigned tothe block model data type so that every model created within the current project from that point onwardswould automatically include the field (populated with default values until required).

Any number of custom attributes can be applied to any data type on creation (or applied to any existingobject in memory).

Filtering the Attribute Manager

You can determine which objects are shown in the top half of the Attribute Manager dialog using thetoggle button toolbar shown in the top left of the screen:

You can enable or disable any of the data type buttons to automatically filter the view of objects inmemory as shown in the top half of the Attribute Managerdialog. Note that the full list of templateswill always be shown as these can be assigned to one or more data types.

The following procedures relate to common tasks that can be performed using the Attribute Manager

Enabling and Disabling Existing Attributes

If you have a loaded data object that is of the wireframe, point, block model, string or drillhole type, youcan switch any of its non-critical attributes on or off as required (this procedure assumes that such dataexists in memory):

1. Open the Attribute Managerusing one of the methods set at the start of this page.

2. Each visual object will be represented by a table row in the top half of the screen.

3. Every non-critical attribute will be shown as a column of data. For each column/object

combination, the attribute cell will either be blank (meaning that the attribute in question is notenabled) or it will state [On], meaning it is either present, or will be applied when the OKbuttonis pressed.

4. Double-click any attribute cell to enable or disable an attribute for an object - the status willalternate between on and off (or vice versa).

5. Click OKto update the selected object(s) in memory - any attributes that have been disabled willno longer appear in the Loaded Data control bar (or the Data Object Manager) and any newly-enabled attributes will be added to the object in memory.




28/30

Creating an Attribute Template

A powerful feature of the Attribute Manager is the ability to create a 'template' of user attributes that willbe applied to each object of a particular data type automatically when it is created. You can also applyattribute templates to existing objects in memory, replacing all user attributes with those specified in thetemplate. This procedure outlines the template creation process only - subsequent procedures detailtemplate usage:


2. The lower half of the dialog is dedicated to the setup of templates. Click Add Template.

3. In the Add New Templatedialog, enter a name for your new attribute template.

4. Click OKand a new row is added to the Template Table.

5. If not already selected, click the newly-added cell and then click Add Column

6. The Add Columndialog is displayed. Enter the details that are relevant to the new attribute and

click OK when complete. Find out more about the Add Column dialog...

7. The new attribute is added as a column to the Template Table. By default, this attribute is set to[On] meaning it will be added if the template is assigned to a data type, and a new object of thattype is created.

8. Continue to add attributes by following steps 5) to 7) until all required attributes are shown.

Assigning Attribute Templates to a Data Type for Automatic Attribute Creation

When a template has been defined, it can either be assigned to an existing object in memory (see below)

or it can be used to created user attributes for every object that is created for a given object type. Thisprocedure shows you how to assign a template to an object type so that each new object that is created,the defined user attributes will be added. This procedure assumes that an attribute template has alreadybeen created (see above):


2. The lower half of the dialog is dedicated to the setup of templates.

3. Assuming that an attribute template already exists (as indicated by the presence of a table row in

Be cautious when enabling and disabling attributes.If an attribute is disabled, the contents ofthat data column will be lost from the object in memory. To prevent this situation, you shouldsave the object(s) in memory to a physical file before editing - that way, you can recall theprevious state of the object if required.

Reintroducing an attribute with the same name as one previously deleted will not re-implementany data values that were set beforehand.

the Template Tablesection), left-click any cell in a template table row to activate it, and clickSelect Default Templates.

4. In the Select Default Templatesdialog, select the drop-down list next to the data type to whichyou wish to assign a template.

5. All attribute templates are available for all visual table types, so select the template you wish to

assign.

6. Click OK.

7. Click OKin theAttribute Managerdialog.

Applying an Attribute Template to an Existing Object

When a template has been defined, you can use it to update the attributes held by any object in memory

(providing that object is a 'visual' table).

This procedure assumes that an attribute template has already been created (see above) and that at leastone visual table exists in memory:


2. Right click the initial row cell for an object in memory (as shown in the top half of the dialog).

3. Select Copy from Template.

4. The Select Templatedialog appears, listing all predefined templates.

5. Select the template containing the attributes you wish to apply.

6. Click OKand the Object Tableupdates to show all active (denoted by an 'On' label) attributes thatwill be applied when the changes are committed.

7. If you are happy that you wish to apply the template to the selected object, click OKand theattributes for that object will be updated.

Creating a New Attribute Template from an Existing Object

You can assign the same template to more than one data type.

Updating Objects in Memory: when you apply an attribute template to an existing data object,any user attributes that currently exist within that object that are notspecified in the template willbe lost.

If you apply a template to an object that contains attributes that already exist within the'receiving' object - that object's attributes and corresponding data values will be preserved.




30/30

If an object in memory contains user attributes that you wish to apply to another object, it may bepertinent to create an attribute template:


2. Right click the initial row cell for an object in memory (as shown in the top half of the dialog).

3. Select Save as New Template.

4. Enter the name for the template you wish to create and click OK.

5. A new row will be added to the Template Tablein the bottom half of the screen.

You can edit, assign, apply or delete this template as required.

Updating an Existing Attribute Template from an Existing Object

If an object in memory contains user attributes that you wish to apply to another object, it may bepertinent to create an attribute template:


2. Right-click the initial row cell for an object in memory (as shown in the top half of the dialog).

3. Select Copy to Template.

4. Select the Template you wish to overwrite and click OK.

5. The selected template will be updated to reflect the user attributes of the source object.
