Parameters
Returns
Promise<IPCB_PrimitiveArc | undefined>
Arc line primitive object
Example
javascript
// 1. 创建待修改的测试圆弧（随机坐标避免与画布已有圆弧重合）
const x = 2000 + Math.floor(Math.random() * 100000);
const y = 2000 + Math.floor(Math.random() * 100000);
const arc = await eda.pcb_PrimitiveArc.create('', 1, x, y, x + 500, y + 300, 90, 10, 1, false);
const arcId = arc.getState_PrimitiveId();
// 2. 读取修改前的线宽与圆心角
const beforeWidth = arc.getState_LineWidth();
const beforeAngle = arc.getState_ArcAngle();
// 3. 批量修改：线宽 10 → 24，圆心角 90 → 120
await eda.pcb_PrimitiveArc.modify(arcId, { lineWidth: 24, arcAngle: 120 });
// 4. modify 返回后需要重新 get() 才能读到画布上的最新值
const refreshed = await eda.pcb_PrimitiveArc.get(arcId);
// 5. 修改类保留现场，供观察修改结果
console.log('primitiveId:', arcId);
console.log('lineWidth:', beforeWidth, '→', refreshed.getState_LineWidth());
console.log('arcAngle:', beforeAngle, '→', refreshed.getState_ArcAngle());1
