ISCH_PrimitiveCircle.toAsync() method
Convert Primitive to Async primitive
Signature
typescript
function toAsync(): ISCH_PrimitiveCircle;1
Returns
Circle primitive object
Example
javascript
// 1. 生成本次运行专用的坐标,避免与之前保留的测试圆重合
const x = 2000 + Math.floor(Math.random() * 8000);
const y = 2000 + Math.floor(Math.random() * 8000);
// 2. 创建一个测试圆(SCH 坐标单位 10mil)
const circle = await eda.sch_PrimitiveCircle.create(x, y, 150);
// 3. 先切换到同步模式,再切回异步模式
circle.toSync();
const asyncCircle = circle.toAsync();
// 4. 异步模式下修改半径,调用 done() 提交到画布
asyncCircle.setState_Radius(250);
await asyncCircle.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_PrimitiveCircle.get(circle.getState_PrimitiveId());
console.log('isAsync after toAsync:', circle.isAsync());
console.log('radius:', 150, '→', refetched.getState_Radius());1
