GEMS Tip – Creating a circle around drillholes collars to display influence areas

By

 

Although GEMS does not have many CAD tools, it is still possible to incorporate specific works related to lines and points within GEMS. We can save time doing this job directly in GEMS rather than exporting the files into external CAD software.

In this article we illustrate the steps to create a circle around the drillholes collars and then draping it into a surface. This process is useful for geologists or surveyors when they need to display an influence area around the drillholes.

 

1. Display drillholes and select collars

Drillholes – Select – Select and snap settings

 

 

2. To visualize the selected collars

Drillholes – Select – Select all drillholes intersects

 

 

3. Create a point in the collar using Point – Create and clicking a collar

Be sure that the snap function is working

 

 

4. Move the point created “X” meters (X = radius of the circle you need) to the left changing coordinates with option Point – Edit – Edit Point

 

 

 

 

 

5. Create the circle using Polyline – Create – Contour line – Status line

Just 1 left-click on the point which was moved “X” meters and then press key A

 

 

 

6. Enter the Radius of the arc you need (“X” value)

 

Press OK and then right-click to save the line. Now there is a circle around the collar

 

 

7. To press this line into the surface, its necessary to visualize in 2D and use Polyline – Multiline – Press onto surface
