IPCB_PrimitiveAttribute.toSync() method
Convert Primitive to Sync primitive
Signature
typescript
function toSync(): IPCB_PrimitiveAttribute;1
Returns
Attribute 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器件重合
const x = 20000 + Math.floor(Math.random() * 80000);
const y = 20000 + Math.floor(Math.random() * 80000);
// 2. 放置测试器件并取出 Designator(编号)属性
const devices = await eda.lib_Device.search('C0402');
const comp = await eda.pcb_PrimitiveComponent.create(devices[0], 1, x, y);
const attrIds = await eda.pcb_PrimitiveAttribute.getAllPrimitiveId(comp.getState_PrimitiveId());
const attrs = await eda.pcb_PrimitiveAttribute.get(attrIds);
const designator = attrs.find(a => a.getState_Key() === 'Designator');
// 3. 读取修改前的属性值
const before = designator.getState_Value();
// 4. 转换为同步图元后直接修改,立即生效(无需 done())
const syncAttr = designator.toSync();
syncAttr.setState_Value(`${before}-SYNC`);
// 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.pcb_PrimitiveAttribute.get(designator.getState_PrimitiveId());
console.log('value:', before, '→', refetched.getState_Value());1
