Constants in OpenSCAD

Based on the input variables and structures provided, here’s the translation of the Go code example to OpenSCAD:

OpenSCAD: Constants#

OpenSCAD supports defining constants with the = operator. Here’s an example of how to define and use constants.

// Declaring a string constant
const s = "constant";

// OpenSCAD modules can act as functions
module main() {
  echo(s);
  
  // Numeric constant
  const n = 500000000;

  // Performing arithmetic with constants
  const d = 3e20 / n;
  echo(d);
  
  // Explicit conversion to integer
  echo(int(d));
  
  // Using the constant in a function call
  echo(sin(n));
}

// Calling the main module to execute
main();

To run this OpenSCAD script, simply open it in the OpenSCAD editor and press F5 to compile or F6 to render.

The script will output the values to the console:

ECHO: "constant"
ECHO: 6e+11
ECHO: 600000000000
ECHO: -0.28470407323754404

Now that we can define and use constants in OpenSCAD, let’s explore more features and capabilities of the language.
