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)); }
