Applying a Maths Script

Source file: howto-how-to-apply-maths-script-on-block-model.htm

Blocks can be modified by performing mathematical operations on them using Evolution's maths script tool.

To 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 the required script.

   • View the existing properties of the model by typing block 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 = block.X + block.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(block.X + block.Y)

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