I'm trying to get more familiar with SolidWorks API. I currently know very little. I would like to write an API in VBA that loops through all of the faces of an assembly which are selected and stores the free body forces from simulation results into an array which will later be written to a file. I'm attempting to accomplish this in small steps. I'm having issues using the GetFreeBodyForcesAndMoments function though. This is what I believe my code is doing.
1) The selected face is identified using the .GetSelectedObject method.
2) I use this .StudyManager function(?) to access the simulation results.
3) I try to store the free body force into a variable called "Force"
I think my arguments are not valid for step 3. Here's my code below. I'm not at all familiar with all of the CosmosWorksLib references.
'Simulation add in has been enabled
'study has been run
'face of interest has been selected
Dim swApp As SldWorks.SldWorks
Dim Part As SldWorks.PartDoc
Dim Face As SldWorks.Face2
Dim Model As SldWorks.ModelDoc2
Dim ModelDocExt As SldWorks.ModelDocExtension
Dim SelMgr As SldWorks.SelectionMgr
Dim Entity As SldWorks.Entity
Dim faceName As String
Dim ret As Boolean
Dim Force As Double
Dim COSMOSWORKS As CosmosWorksLib.COSMOSWORKS, CWAddinCallBack As CosmosWorksLib.CWAddinCallBack, ActDoc As CosmosWorksLib.CWModelDoc
Dim StudyMngr As CosmosWorksLib.CWStudyManager, Study As CosmosWorksLib.CWStudy, CWMesh As CosmosWorksLib.CWMesh
Dim CWFeatObj As CosmosWorksLib.CWResults
Set swApp = CreateObject("SldWorks.Application")
' Get active document
Set Part = swApp.ActiveDoc
Set Model = Part
Set SelMgr = Model.SelectionManager
Set Face = SelMgr.GetSelectedObject6(1, -1)
Set CWAddinCallBack = swApp.GetAddInObject("SldWorks.Simulation")
Set COSMOSWORKS = CWAddinCallBack.COSMOSWORKS
Set ActDoc = COSMOSWORKS.ActiveDoc()
Set StudyMngr = ActDoc.StudyManager()
Set Study = StudyMngr.GetStudy(0)
Set CWFeatObj = Study.Results
'If CWFeatObj Is Nothing Then ErrorMsg swApp, "Failed to get result object": GoTo Lastline
Force = CWFeatObj.GetFreeBodyForcesAndMoments(Nothing, 1, Face, 0, 0)
Could the issue be with the last argument in the GetFreeBodyForcesAndMoments function? I'm thinking that if it's set to 0 it means there's no error code. Here's a blurb on the function from SW API help
Function GetFreeBodyForcesAndMoments( _
ByVal DispPlane As System.Object, _
ByVal SelectedRefPoint As System.Object, _
ByVal ArraySelectedEntities As System.Object, _
ByVal NUnits As System.Integer, _
ByRef ErrorCode As System.Integer _
) As System.Object
Any help is greatly appreciated. Thanks!
