Curve

Creating a Curve

let model = await SketchUpApi.getActiveModel();
await model.performOperation(async operation => {
  const result = operation.createCurve(model, [
    [0, 0, 0],
    [10, 0, 0],
    [10, 10, 0],
    [0, 10, 0],
  ]);
  const curve = await operation.entityForRef(result.curve);
  console.log('Curve:', curve);
  console.log('Edges:', curve.edges.length);
}, 'Create a curve');

Creating a Circle (ArcCurve)

let model = await SketchUpApi.getActiveModel();
await model.performOperation(async operation => {
  const result = operation.createCircle(
    model,
    [0, 0, 0],  // center
    [0, 0, 1],  // normal (Z-axis)
    10,         // radius
  );
  const circle = await operation.entityForRef(result.curve);
  console.log('Circle:', circle);
  console.log('Radius:', circle.radius);
  console.log('Is circular:', circle.circular);
}, 'Create a circle');

Creating an Arc (ArcCurve)

let model = await SketchUpApi.getActiveModel();
await model.performOperation(async operation => {
  const result = operation.createArc(
    model,
    [0, 0, 0],     // center
    [10, 0, 0],    // xaxis (defines radius and start direction)
    [0, 0, 1],     // normal (Z-axis)
    10,            // radius
    0,             // start angle
    Math.PI,       // end angle (180 degrees)
  );
  const arc = await operation.entityForRef(result.curve);
  console.log('Arc:', arc);
  console.log('Radius:', arc.radius);
  console.log('Start angle:', arc.startAngle);
  console.log('End angle:', arc.endAngle);
}, 'Create an arc');
