Design Directions
It is very important to ensure that the Fixed Cross-Sectional design strings run in the correct direction, i.e. the direction of mining. If not, problems will occur with the sequence and the scheduling of the design.
Data Validation Wizard
The Design Data Validation Wizard is used to repair errors which become inherit to design data. The wizard steps the user through the process of cleaning the data.
The Data Validation Wizard contains the following tabs along the top of the screen:
1. File Selection: the initial screen lists the visual design tables associated with the current project. The wizard investigates all Design Strings in the project.
You can choose to validate Fixed Cross Sections, Outlines and/or Complex Solids that are already associated with your project, or you can use the ellipsis button (...) to select any data file on disk (in Datamine binary format only - if other formats require
2. Duplicate Strings: remove duplicate centrelines from your design.
Duplicate strings are usually the result of the same file being opened on multiple occasions and then saved back to the original file. It can also result from importing 'unclean' CAD data.
The generation of a design is based on centerlines. When centerlines are duplicated it has the potential to generate double the solids and account for double the volume. It is imperative to remove duplicates from all designs. This panel contains the following fields:
Duplicate Checking Precision: can be set to check for points which are not exactly the same. To check for exact duplicate strings, leave the checking precision set to zero.
Compare String Properties: can be used to specify whether design definitions are used to define duplicate strings. If the check bog is toggled on, Studio 5D Planner will only flag duplicate strings which do not share the same COLOUR, LSTYLE AND SYMBOL combination. Otherwise, all spatial duplicates will be flagged.
Flag Partial Duplicates: can be toggled to on search for strings which share two or more points. This tool is especially useful for highlighting fixed cross sectional strings that share many points but each have at least one unique point.
Duplicate Example 1
The strings shown in the fixed cross sectional example to the left would generally not be flagged as duplicates. However, if the precision was set to '0.5', points A2 and B1 would be seen as duplicate and points A3 and B2 would also be seen as duplicate. Still, if Flag Partials was not checked, these strings would not be seen as duplicate as points A1 and B3 would both be seen as unique.
Hence, if the precision was set to '0.5' and the Flag Partials toggle was activated for Fixed Cross Sectionals, these strings would be seen as duplicate. If the Compare String Properties toggle for Fixed Cross Sectionals was also active, these strings would not be seen as duplicate as string A has COLOUR 7 while string B has COLOUR 8.
Duplicate Example 2
In this second example, running with a precision of 0.5, the Flag Partials check box for a design type would not need to be toggled on to find string B as a duplicate. As all of the points on string B can be found on string A, string B would be flagged as a duplicate.
If the Check Design Definition check box was toggled for Fixed Cross Sectionals, string B would not be found as a duplicate, as it does not have the same COLOUR, LSTYLE AND SYMBOL combination as string A. Remember that it is this combination of the three key fields that determines whether a design entity is unique.
3. Resolve String Points: this stage of the wizard is used to detect and rectify points on Fixed Cross Sectional design strings that are found to be within a specified distance. The existence of such closely spaced points is often due to a string being projected to a wireframe. Strings containing points too close to each other can generate problems when generating segments.
Where the points on a string are closely spaced, errors can be generated when creating segment outlines or wireframing. It is recommended that closely spaced points be resolved. The handling of multiple closely spaced points will be performed either by deleting the second point, or by averaging the distance of the two points along the string segment. You can elect to perform this operation on any design types found within the project (Fixed Cross Sectionals, Outines etc.) by toggling the relevant option button on the right of the screen.
Checking Distance: enter a value below which multiple points will be treated as being 'too close', and made subject to one of the following actions:
Delete successive point....: of the group of close points, the first point will be classed as the 'survivor', whilst all subsequent points (according to the defined point vertex order) that fall within the Checking Distance will be deleted.
Create a new average point...: if selected, the distance between the original point, and the next in sequence will be mean averaged, and both points replaced with a point at the average distance. This process continues until points are not found within the Checking Distance.
4. Severe Angle Changes: checks string segments for azimuth and/or dip changes
