I am currently working with iLOGIC and the API to try and get dimensions to measure and output directly to a BOM.

I am working with the following exported inventor user parameters that the BOM will look for:
output_D (for Depth)
output_W (for Width)
output_L (for Lenth)

inside the IPT files, an Ilogic rule set to the event trigger 'BeforeSaveDocument':

========
'save the AllWorkFeatures status to reset once run
AWF = (ThisApplication.activedocument.ObjectVisibility.AllWorkFeatures)
ThisDoc.Document.ObjectVisibility.AllWorkFeatures = (False)
'save the ConstructionSurfaces status to reset once run
CSURF = (ThisApplication.activedocument.ObjectVisibility.ConstructionSurfaces)
ThisDoc.Document.ObjectVisibility.ConstructionSurfaces = (False)

'get max dimension
Dim i As String
i = MaxOfMany(Measure.ExtentsLength, Measure.ExtentsWidth, Measure.ExtentsHeight)
'get min dimension
Dim j As String
j = MinOfMany(Measure.ExtentsLength, Measure.ExtentsWidth, Measure.ExtentsHeight)
'set max and min to output parameters
Parameter("output_L") = i
Parameter("output_W") = j
'get the remaining dimension
Dim k As String
k = Measure.ExtentsLength + Measure.ExtentsWidth + Measure.ExtentsHeight - i - j
'set the remaining dimension
Parameter("output_D") = k

'reset the AllWorkFeatures/ConstructionSurfaces statuses... statusii?
ThisDoc.Document.ObjectVisibility.AllWorkFeatures = (AWF)
ThisDoc.Document.ObjectVisibility.ConstructionSurfaces = (CSURF)
==========

I have a very similar rule being triggered inside the Assembly files also. The issue I am running into is that if the assembly file contains a part that has a construction surface that is visible inside it, the values for the extents of the assembly return the extents of that surface instead of the solids only. As you can see I have suspended the visability for the constructionsurfaces inside the IPT files while writing the values to the parameters but I reset them to as they were before so as to not interupt the user. This means I must also accomplish this goal in the IAM files too.

How do I control the visibility of the 'ConstructionSurfaces' inside the assembly?

Thanks in advance.
