In this tip of the month, we will see how to construct 3D Benches using polyline contours. This will allow you to easily design blast patterns for a specific area. To do so:   

  1. Draw the polyline contours of each bench. Each bench will have 2 polylines; one representing the bench and the other for the toe.  
  1. From the 3D Bench module in the Modeling category, use the “Draw Surface” (3DBS) command to draw a surface for each polyline contour.  
  • Select the target.  
  • You may select elevation points using the options “Layer” or “Objects” under Elevation points. If not, select “Elevation” or “None” to insert a flat surface.  
  • Select the elevation method to be used when drawing a surface.  
  1. Perform the same operation on the Crest.  
  1. Use the “Construct Bench” (3DBC) command to construct a 3D bench between the surfaces.  
  1. Using the “Tonnage” (3DBT) command, calculate the total volume of the 3D bench by entering the density and a swell factor.  
  1. You may also manipulate this bench by cutting it into slices. Using the “Slice Solids” (PROMSLICE) command:  
  • Draw a closed polyline enclosing the area to be cut  
  • Select the command  
  • Select the 3D bench to be cut and hit Enter  
  • Select the polyline and hit Enter
