Maths Scripts for Solid Models

You can modify solid models by performing mathematical operations on them using Evolution's maths script tool. For information on maths functions available in Evolution, see Mathematical functions.

To create and apply a maths script on a block model:

  1. Right-click the model in the project explorer and select Add Maths Script.

  2. Evolution will create a script object in the project explorer under the block model. Double-click this object to open the script window in the viewer.

  3. Write a script.

    • View the existing properties of the model by typing solid followed by a full stop.

    • Modify the existing properties of the model by typing in the attribute name on the left, followed by an expression on the right.

      existingAttribute = solid.X + solid.Y

    • Create temporary attributes (that will not be written to the model and will only be used within the script) by wrapping the expression on the right-hand side inside a define function.

      tempAttribute = define(solid.X + solid.Y)

  4. Click Run Script.
  5. Check that the new variable has been calculated correctly by opening the block model in the viewer and checking its properties.

Example script

            
// Excavation costs based on material, and equipment

            
excavateCO = define(if(solid.MATERIAL="CO",solid.Tonnage_ad * 3.35,0))

            
excavateTS = define(if(solid.MTW_Bench<>"Bowfield" AND solid.MATERIAL<>"CO", solid.Volume*1.91 ,0))

            
excavateDL = define(if(solid.MTW_Bench="Bowfield" AND solid.MATERIAL<>"CO", solid.Volume*1.00 ,0))

            
excavate = define(excavateCO + excavateTS + excavateDL)
