Extracting column loads and LL reduction factors use RAM DA

Chiang Ng — Mon, 31 Dec 2018 22:21:41 GMT

I'm trying to extract gravity column loads and live load reduction factors. I tried using the interface IGravityLoads1, with the GetStoryGravityReactOnCol method. But I think I am misunderstanding the input parameter for "lColNum", the column index. It doesn't seem to work with either the IColumn.lUID nor IColumn.lLabel. What should this lColNum input be?

Is there a similar example available as the one for beam forces in this thread?

RAM DataAccess, using IModelGeometry1

Chiang Ng — Mon, 22 Jan 2018 19:13:58 GMT

I'm using the RAM DataAccess API and not sure if I am using IModelGeometry1 in the VBA macro correctly. I ultimately want to populate a table with the Support type and Support ID for every beam, for both start and end joints. I initialized interfaces and followed with a loop for each beam. But I'm getting a compile error. Any help to correct the VBA below is much appreciated.

Dim IModelGeometry1 As RAMDATAACCESSLib.IModelGeometry1

Set IModelGeometry1 = RAMDataAcc1.GetDispInterfacePointerByEnum(IModelGeometry_INT)

R = 14 'start on this row

           lNumBeams = IBeams.GetCount
            For lBeam = 0 To lNumBeams - 1
                Set IBeam = IBeams.GetAt(lBeam)
                lUID = IBeam.lUID
                    Cells(R, 2) = strStoryID
                    Cells(R, 3) = IBeam.lLabel
                    Cells(R, 4) = IBeam.strSectionLabel
                    IModelGeometry1.GetBeamSupportInfo peSupportTypeStart, plSupportIDStart
                    Cells(R, 5) = peSupportTypeStart
                    Cells(R, 6) = plSupportIDStart

                    R = R + 1
            Next 'Beam
