PCB_PrimitiveArc.modify() method

This API is provided as a beta preview for developers and may change based on feedback that we receive. Do not use this API in a production environment.

Modify Arc line

Signature

function modify(
	primitiveId: string | IPCB_PrimitiveArc,
	property: {
		net?: string;
		layer?: TPCB_LayersOfLine;
		startX?: number;
		startY?: number;
		endX?: number;
		endY?: number;
		arcAngle?: number;
		lineWidth?: number;
		interactiveMode?: EPCB_PrimitiveArcInteractiveMode;
		primitiveLock?: boolean;
	},
): Promise<IPCB_PrimitiveArc | undefined>;

Parameters

Parameter	Type	Description
primitiveId	string | IPCB_PrimitiveArc	Primitive ID
property	{ net?: string; layer?: TPCB_LayersOfLine; startX?: number; startY?: number; endX?: number; endY?: number; arcAngle?: number; lineWidth?: number; interactiveMode?: EPCB_PrimitiveArcInteractiveMode; primitiveLock?: boolean }	Modify Parameter

Returns

Promise<IPCB_PrimitiveArc | undefined>

Arc line primitive object

Remarks

property.arcAngle 合法域为 0 < |arcAngle| < 360，不支持 0° 或 ±360° 整圆：两点式圆弧无法表达整圆，传入将抛错

Example

// 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());
