Create Pattern

On the Drillhole | Planning tab, in the Planning group: Click Create Pattern to generate a regular pattern of planned holes and add them to the planning layer. The holes of the pattern can be adjusted interactively.

When you select Finish Plan, the pattern is saved to the Drillhole Planning layer.

Define Pattern

Click the Edit Extents button to collapse the form and interactively adjust the extents and the orientation of the pattern. The corresponding values in the Define Pattern group of the form will be updated.

Pick point in Vizex

Click the Pick point in Vizex button in the Define Pattern group, to interactively pick the coordinates of the East and North origin. The East and North origin values in the form will be updated.

East and North origin

Enter the East origin and the North origin of the pattern (this point represents the South-West corner of the pattern).

Bearing

Enter a Bearing in a clockwise direction from zero degrees (North) to orient the pattern to the geology or any previous surveys. When looking along the bearing the origin is always in the bottom-left corner, drill lines run from left to right, and each new line is further from the origin, as shown in the diagram below:

Width

Enter the width of the pattern (see diagram above).

Length

Enter the distance from the origin on which to calculate holes. This is measured in the direction of the bearing (see diagram above).

Hole spacing

Define the spacing between the holes along each line.

Line spacing

Define the spacing between the lines in the direction of the origin.

Edit Extents

Click the Edit Extents button to collapse the form and visually adjust the extents of the pattern. Interactively adjusting the extents rectangle in Vizex will update the values in the form.

Pattern

Choose between a Rectangular or a Staggered grid pattern. The Staggered pattern is based on a diamond grid. The spacing distance usually ranges between 100% and 200% of the burden distance.
