In this edition of Tips & Tricks we'll show you how easy it is to insert vertical sections interpreted and done the traditional way (pen and paper) into MineSight to guide your geological modeling.
So, get to work!
First, let's take as an example a vertical section not orthogonal to the N/S and E/W axes. The example will be performed in the section highlighted in red in the image below.
For this example, MineSight Plot is used to first print the section with the holes and descriptions, topography and the grid of axes for later georeferencing. So the section is interpreted by hand, and then the steps below are followed.
Take note that you need to have in the handmade section, the grid of Z axes and the North or East, depending on which reader chooses to work.
In this case we have both axes, but we chose to use the EW grid. As there was no rightmost EW axis in the section, this one was designed.
Once the boundary coordinates are known, which in this case we will only use the extreme points highlighted in red, we can use them to plot the boundary rectangle of the section in MineSight and then use georeferencing.
In this case, only 4 points were used, but this method is used for as many points as necessary to better georeference your image.
From there, in MS3D, configure its respective section in the PLANE option and thus change the screen to 2D.
Once in 2D mode, make a 2D polygon (POLYLINE menu > CREATE 2D > POLYGON) using the section coordinates.
Note that this step is important to do in 2D, especially if the section is non-orthogonal, because using the 2D option, you will guarantee that the polygon will be made in the plane of the section, not needing to know the value of the extra coordinate, which in this case is the NS coordinate.
Once the boundary polygon of the section is made, it is necessary to create a surface on which it will be projected. For this, you can use the tool from the SURFACE > TRIANGULATE SURFACE > INSIDE POLYLINE BOUNDARY menu and with that create a surface on the limits of this polygon.
With the surface done, use the SNAP POINT option in the SNAP menu and open the TEXTURE SURFACE TOOL (FROM IMAGE) in the UTILITIES menu.
You will be able to georeference your image without having to worry about typing the coordinates. First load the image, select which surface will be plotted and adjust the zoom on the image to start georeferencing.
Simply click on the option to select the control point on the image and then click on where this point on the image will be correlated in MineSight's 3D space and select the corresponding point on the MS3D screen. Do this for all control points, always remembering to click first on the image and then on the MS3D screen.
After applying, the section will be plotted to the chosen surface.
This is just a way to plot the vertical sections without having trouble with georeferencing coordinates. You can also plot on a surface created from GRIDSETS.
We hope that these tips can help you in the most "running" moments of your day-to-day.
To the next.
