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 the Add new maths script option.

   

2. A script will be created in the project explorer under the block model. Double click this object to open the Maths Script window in the viewer.



3. Write a script.

   • Existing properties of the model can be read by typing "block" followed by a full stop.

   • Existing properties of the model can be modified by typing in the attribute name on the left, followed by an expression on the right.

     existingAttribute = block.X + block.Y

   • Temporary attributes which will not be written to the model and only used within the script can be created 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.
