ZW3D二次开发_获取造型的投影面积及最大长宽

函数：

ZwEntityProjectToPlaneAreaGet

支持版本：

ZW3D 2026 SP1及以上

代码：

void 零件_查询_测量_投影面积()
{
	szwEntityHandle entityHandle = {};
	ZF_CALL(ZwEntityGetByPick("选择造型", ezwEntityInputOption::ZW_INPUT_SHAPE, 0, &entityHandle));

	szwEntityHandle planeHandle = {};
	ZF_CALL(ZwEntityGetByPick("选择平面", ezwEntityInputOption::ZW_INPUT_DATUM_PLANE, 0, &planeHandle));

	szwProjectAreaOption option{};
	option.count = 1;
	option.entityHandleList = &entityHandle;//造型
	option.plane = planeHandle;//平面
	option.addCurveFlag = ZW_PROJECT_AREA_FLAG_ALL_CURVES;//全部曲线
	szwProjectAreaProp areaProp{};
	ZF_CALL(ZwEntityProjectToPlaneAreaGet(option, &areaProp));

	WriteMessage("最大投影面积 = %.2f", areaProp.area);
	WriteMessage("X最大距离 = %.2f", areaProp.xMaxLen);
	WriteMessage("Y最大距离 = %.2f", areaProp.yMaxLen);

	ZF_CALL(ZwEntityHandleFree(&entityHandle));//内存释放
	ZF_CALL(ZwEntityHandleFree(&planeHandle));
}
