### Flatten and Render to STEP Format

Source: https://docs.rs/monstertruck/0.3.2/src/monstertruck/lib.rs.html?search=

This snippet demonstrates flattening a topology and rendering it into the STEP file format. It includes assertions to verify the output starts with the correct header and contains expected keywords.

```rust
#![allow(unused_variables)]
fn main() {
//! let punched = solid::and(&cube, &cylinder, 0.05)?;
//!
//! // Flatten the topology and render as STEP.
//! let compressed = punched.compress();
//! let step = CompleteStepDisplay::new(
//!     StepModel::from(&compressed),
//!     StepHeaderDescriptor {
//!         organization_system: "monstertruck-doc".to_owned(),
//!         ..Default::default()
//!     },
//! )
//! .to_string();
//!
//! assert!(step.starts_with("ISO-10303-21;"));
//! assert!(step.contains("MANIFOLD_SOLID_BREP"));
//! # Ok(())
//! # }

### Subtract Cylinder from Cube and Export STEP

Source: https://docs.rs/monstertruck/0.3.2/src/monstertruck/lib.rs.html

This example demonstrates building a cuboid and a cylinder, performing a boolean subtraction, and exporting the result as a STEP string. It requires the 'step' and 'solid' features to be enabled.

```rust
# #[cfg(not(all(feature = "step", feature = "solid")))]
# fn main() {}
# #[cfg(all(feature = "step", feature = "solid"))]
# fn main() -> anyhow::Result<()> {
use monstertruck::modeling::*
use monstertruck::solid;
use monstertruck::step::save::{CompleteStepDisplay, StepHeaderDescriptor, StepModel};

// Unit cuboid centred on the origin.
let cube: Solid = primitive::cuboid(BoundingBox::from_iter([
    Point3::new(-0.5, -0.5, 0.0),
    Point3::new(0.5, 0.5, 1.0),
]));

// Cylinder of radius 0.3, axis along +Z, that pierces the cube top to bottom.
let seed = builder::vertex(Point3::new(0.3, 0.0, -0.1));
let rim = builder::revolve(
    &seed,
    Point3::new(0.0, 0.0, -0.1),
    Vector3::unit_z(),
    builder::SweepAngle::Closed,
    4,
);
let base = builder::try_attach_plane(&[rim])?;
let mut cylinder: Solid = builder::extrude(&base, Vector3::unit_z() * 1.2);

// Invert the cylinder so `and` performs a subtraction.
cylinder.not();

```

### Subtract Cylinder from Box and Export STEP

Source: https://docs.rs/monstertruck/0.3.2/monstertruck/index.html?search=

This example demonstrates building a cuboid and a cylinder, performing a boolean subtraction using the 'and' operation (after inverting the cylinder), and exporting the resulting solid as a STEP file string. Ensure 'modeling' and 'step' features are enabled.

```rust

use monstertruck::solid
use monstertruck::step::save::{CompleteStepDisplay, StepHeaderDescriptor, StepModel}

// Unit cuboid centred on the origin.
let cube: Solid = primitive::cuboid(BoundingBox::from_iter([
    Point3::new(-0.5, -0.5, 0.0),
    Point3::new(0.5, 0.5, 1.0),
]));

// Cylinder of radius 0.3, axis along +Z, that pierces the cube top to bottom.
let seed = builder::vertex(Point3::new(0.3, 0.0, -0.1))
let rim = builder::revolve(
    &seed,
    Point3::new(0.0, 0.0, -0.1),
    Vector3::unit_z(),
    builder::SweepAngle::Closed,
    4,
)
let base = builder::try_attach_plane(&[rim])?
let mut cylinder: Solid = builder::extrude(&base, Vector3::unit_z() * 1.2)

// Invert the cylinder so `and` performs a subtraction.
cylinder.not()
let punched = solid::and(&cube, &cylinder, 0.05)?

// Flatten the topology and render as STEP.
let compressed = punched.compress()
let step = CompleteStepDisplay::new(
    StepModel::from(&compressed),
    StepHeaderDescriptor {
        organization_system: "monstertruck-doc".to_owned(),
        ..Default::default()
