How to read parameters of placed GDL panel in Curtian Wall?

How to read the parameter value of curtain wall panels? Curtain wall panels are made by GDL objects. The usual way (ACAPI_Element_GetMemo(guid, &memo, APIMemoMask_AddPars) of reading parameters for objects does not work, because the panels do not have memo. Is there an alternative way to read panel parameters?

 

GSErrCode GetCWPanelsForCWall(const API_Guid& elemGuid, GS::Array<API_Guid>& panelGuid) {
	GSErrCode			err = NoError;
	API_Elem_Head elementhead = {};
	elementhead.guid = elemGuid;
	err = ACAPI_Element_GetHeader(&elementhead);
	if (err != NoError) return err;
	if (!elementhead.hasMemo) return err;
	API_ElementMemo	memo;
	BNZeroMemory(&memo, sizeof(API_ElementMemo));
	bool isDegenerate;
	err = ACAPI_Element_GetMemo(elemGuid, &memo, APIMemoMask_CWallPanels);
	if (err != NoError) {
		ACAPI_DisposeElemMemoHdls(&memo);
		return err;
	}
	GSSize nPanels = BMGetPtrSize(reinterpret_cast<GSPtr>(memo.cWallPanels)) / sizeof(API_CWPanelType);
	for (Int32 idx = 0; idx < nPanels; ++idx) {
		err = ACAPI_Database(APIDb_IsCWPanelDegenerateID, &memo.cWallPanels[idx].head.guid, &isDegenerate);
		if (!isDegenerate && memo.cWallPanels[idx].hasSymbol) {
			panelGuid.Push(memo.cWallPanels[idx].symbolID);
			API_Elem_Head panelhead = {};
			panelhead.guid = memo.cWallPanels[idx].symbolID;
			err = ACAPI_Element_GetHeader(&panelhead);
			if (!panelhead.hasMemo) {
				ErrorBeep("ACAPI_Element_GetMemo", err);
			}
		}
	}
	ACAPI_DisposeElemMemoHdls(&memo);
	return err;
}

If you have the GUID of the placed library part instance (= GDL based element = symbol), then you can get its parameters by using the APIAny_OpenParametersID, APIAny_GetActParametersID and APIAny_CloseParametersID methods. See the GetGDLParametersOfSymbol function below.

This works for CWPanels also.

	bool isDegenerate = false;
	ACAPI_Database (APIDb_IsCWPanelDegenerateID, (void*)(&cwPanel.head.guid), &isDegenerate);

	return cwPanel.symbolID;
}

GSErrCode GetSymbolGuidOfCWPanel (const API_Guid& cwPanelGuid, API_Guid& symbolGuid)

	if (err != NoError) {
		return err;
	}

	symbolGuid = GetSymbolGuidOfCWPanel (elem.cwPanel);
	if (symbolGuid == APINULLGuid) {

	}

	return NoError;

	if (err != NoError) {

		return err;
	}

	const GSSize nPanels = BMGetPtrSize (reinterpret_cast<GSPtr>(memo.cWallPanels)) / sizeof (API_CWPanelType);
	for (Int32 idx = 0; idx < nPanels; ++idx) {
		const API_Guid symbolGuid = GetSymbolGuidOfCWPanel (memo.cWallPanels[idx]);
		if (symbolGuid != APINULLGuid) {
			panelSymbolGuids.Push (std::move (symbolGuid));
		}
	}

	ACAPI_DisposeElemMemoHdls (&memo);
	return err;
}

}

	Int32	addParNum = BMGetHandleSize ((GSHandle)params) / sizeof (API_AddParType);
	for (Int32 ii = 0; ii < addParNum; ++ii) {
		API_AddParType& actualParam = (*params)[ii];
		// Do whatever you want with it
		UNUSED_VARIABLE (actualParam);
	}

	return NoError;
}

Don't forget that the API_AddParType list returned by the APIAny_GetActParametersID method is just a copy! So if you modify it, then the parameters of the placed element won't be changed automatically. You have to call the ACAPI_Element_ChangeMemo explicitly to modify the parameters of the element:

API_ElementMemo	elemMemo = {};
elemMemo.params = params;

ACAPI_Element_ChangeMemo (symbolGuid, APIMemoMask_AddPars, &elemMemo);
