Creating Block Models from Points Data and Applying a Rotation

The article explains how to visualize geophysical data as a block model by first measuring point spacing along X, Y, and Z axes and determining rotation. In the example, distances are 7.07 and 5 for X and Z, with a 45° azimuth in Y. Using this, users navigate to Block Model Create Block Model from Imported Data, set a 45° rotation, and define block sizes accordingly to generate the model.

Let’s say you import some geophysical data points and would like to visualize it as a block model file. First, identify the distances between points along all axes (X, Y, Z) and determine if a rotation is needed.
 

In the example below, we measure point spacing in different axes, with distances of 7.07 and 5 in the X and Z directions, respectively, and an azimuth of 45° in the Y direction.

 

 

With this information, we can proceed by navigating to Block Model > Create Block Model from Imported Data. Here, we’ll define the rotation and specify the block size based on our measurements (45° rotation, and block sizes of 7.07 in the X and Y axes and 5 in the Z axis).

Here is the result:
