Creating an window on wall using C++ code

Hi Team,
I was trying to create a wall and window using and Add-on. I was able to create a wall but when I added the code for window nothing got rendered.
I have added the code below
archiCAD 25, IDE XCode

static GSErrCode CreateWallElement (double begX, double begY, double endX, double endY, API_Guid& placedWallGuid) { GSErrCode err = NoError; API_Element wallElement = {}; SetAPIElementType (wallElement, API_WallID); err = ACAPI_Element_GetDefaults (&wallElement, nullptr); if (err != NoError) { return err; } wallElement.wall.begC = { begX, begY }; wallElement.wall.endC = { endX, endY }; wallElement.wall.referenceLineLocation = APIWallRefLine_Center; err = ACAPI_Element_Create (&wallElement, nullptr); if (err != NoError) { return err; } placedWallGuid = wallElement.header.guid; return NoError; } static GSErrCode CreateWindowElement (double x, double y, API_Guid& placedWindowGuid, API_Guid& placedWallGuidLeft) { GSErrCode err = NoError; API_Element windowElement = {}; SetAPIElementType (windowElement, API_WindowID); err = ACAPI_Element_GetDefaults (&windowElement, nullptr); if (err != NoError) { return err; } windowElement.window.startPoint.x = x; windowElement.window.startPoint.y = y; windowElement.window.openingBase.width = 0.3; windowElement.window.openingBase.height = 0.3; windowElement.window.jambDepth = 0.1; windowElement.window.owner = placedWallGuidLeft; err = ACAPI_Element_Create (&windowElement, nullptr); if (err != NoError) { return err; } placedWindowGuid = windowElement.header.guid; return NoError; } main function() { GS::Array<API_Guid> placedElementGuids; API_Guid placedWallGuidLeft; CreateWallElement (0, 0, 0, 10, placedWallGuidLeft); placedElementGuids.Push (placedWallGuidLeft); API_Guid placedWindowGuid; err = CreateWindowElement(10, 10, placedWindowGuid, placedWallGuidLeft); placedElementGuids.Push(placedWindowGuid); err = ElementGroup_Create (placedElementGuids); if (err != NoError) { return APIERR_CANCEL; } }

HI Team,
Getting this error in debug console

err GS::GSErrCode -2130313112

This link shows the error as
The passed parameters are inconsistent.

I am thinking some of the mandatory parameters was missing or not provided correctly, but the error message to general.
Any comments?

Hi Roni!

You are missing the ElementMemo data structure. It's necessary for a lot of elements and especially for elements based on library parts. For such elements, it includes the values for the GDL-Object parameters. Here are some additional & adapted lines you'd need:

API_ElementMemo windowMemo{}; // Disposes the handles at the end of the lifetime of 'memoDisposer'. // So in this case when exiting the function. GS::OnExit memoDisposer ([&windowMemo] {ACAPI_DisposeElemMemoHdls (&windowMemo); }); // ... // Get memo from defaults here err = ACAPI_Element_GetDefaults (&windowElement, &windowMemo); if (err != NoError) { return err; } // ... // and use when creating the window here err = ACAPI_Element_Create (&windowElement, &windowMemo);

Also next time please post this in the Archicad C++ API Subforum. I think all of us programmers missed it here ^^

Hope that helps!

Bernd
