Embed Directive in OpenSCAD

Here’s the translation of the Go code to OpenSCAD, with explanations in Markdown format suitable for Hugo:

Our first program will demonstrate how to create a simple 3D object and use basic operations in OpenSCAD. Here’s the full source code:

// Create a cube with dimensions 10x10x10
cube([10, 10, 10]);

// Translate the cube 20 units along the x-axis
translate([20, 0, 0]) {
    cube([10, 10, 10]);
}

// Create a sphere with radius 5
translate([0, 20, 0]) {
    sphere(r = 5);
}

// Create a cylinder with radius 5 and height 10
translate([20, 20, 0]) {
    cylinder(h = 10, r = 5);
}

In OpenSCAD, we don’t have the concept of a main function or imports like in some programming languages. Instead, the entire script is executed from top to bottom to generate the 3D model.

To run this OpenSCAD script:

1. Save the code in a file with a .scad extension, for example, basic_shapes.scad.
2. Open the file in the OpenSCAD application.
3. Click on the “Compile and Render” button (F6) to see the 3D model.

The script will create four basic shapes:

1. A cube at the origin (0, 0, 0)
2. Another cube translated 20 units along the x-axis
3. A sphere translated 20 units along the y-axis
4. A cylinder translated 20 units along both x and y axes

You can rotate the view, zoom in/out, and pan around to examine the 3D model in the OpenSCAD viewer.

To export the 3D model:

1. Go to “File” > “Export” in the OpenSCAD menu.
2. Choose the desired file format (e.g., STL, OBJ, OFF).
3. Select a filename and location to save the exported 3D model.

Now that we can create and visualize basic 3D shapes in OpenSCAD, let’s explore more advanced features and operations in the language.
