ISCH_PrimitiveArc.setState_StartX() 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.

Set the property state: start point X

Signature

function setState_StartX(startX: number): ISCH_PrimitiveArc;

Parameters

Parameter	Type	Description
startX	number	Start point X

Returns

ISCH_PrimitiveArc

Arc primitive object

Example

// 1. 生成本次运行专用的坐标，避免与之前保留的测试圆弧重合
const x = 2000 + Math.floor(Math.random() * 8000);
const y = 2000 + Math.floor(Math.random() * 8000);

// 2. 创建一段测试圆弧，起点 (x, y)（SCH 坐标单位 10mil）
const arc = await eda.sch_PrimitiveArc.create(x, y, x + 100, y + 100, x + 200, y, null, null, 6, 1);

// 3. 读取修改前的起点 X
const before = arc.getState_StartX();

// 4. 切换异步模式并将起点 X 左移 60
const asyncArc = arc.toAsync();
asyncArc.setState_StartX(x - 60);
await asyncArc.done();

// 5. 从画布重新读取，确认修改已生效（保留现场供观察）
const refetched = await eda.sch_PrimitiveArc.get(arc.getState_PrimitiveId());

console.log('startX:', before, '→', refetched.getState_StartX());
