Stair Creation in ArchiCAD 25 / CPP code

Hi All,

I was trying to create a dog-legged stair with a mid-land after 10 steps in archiCad using CPP code.

I was able to render the stair, but in the mid-land section a step was rendered. I have attached the screenshot of what I expected (right image) and what got rendered (left image).

Like in ArchiCAD UI, Can we specify the stair flight and mid-landing positions in CPP api's?

Below code was used

NB: ArchiCAD Version 25

API_GetPolyType polyInfo = {}; polyInfo.nCoords = 4; polyInfo.nArcs = 0; polyInfo.coords = (API_Coord**)BMhAllClear((polyInfo.nCoords + 1) * sizeof(API_Coord)); (*polyInfo.coords)[1] = { convertFeetToM(0), convertFeetToM(0) }; (*polyInfo.coords)[2] = { convertFeetToM(0), convertFeetToM(-12.3194) }; (*polyInfo.coords)[3] = { convertFeetToM(-3.0020), convertFeetToM(-12.3194)}; (*polyInfo.coords)[4] = { convertFeetToM(-3.0020), convertFeetToM(0) }; API_Element element; API_ElementMemo memo; BNClear (element); BNClear (memo); element.header.typeID = API_StairID; err = ACAPI_Element_GetDefaults (&element, &memo); // element.stair.inputDirection = APISD_Upward; if (err != NoError) { ACAPI_WriteReport ("ACAPI_Element_GetDefaults (Stair) has failed with error code %ld!", true, err); ACAPI_DisposeElemMemoHdls (&memo); return err; } element.stair.totalHeight = convertFeetToM(height); element.stair.flightWidth = convertFeetToM(width); element.stair.riserHeight = convertFeetToM(riserHeight); element.stair.stepNum = steps; element.stair.baselinePosition = APILP_Center; memo.stairBaseLine.coords = polyInfo.coords; memo.stairBaseLine.parcs = polyInfo.parcs; memo.stairBaseLine.polygon.nCoords = polyInfo.nCoords; memo.stairBaseLine.polygon.nArcs = polyInfo.nArcs; err = ACAPI_Element_Create (&element, &memo);
