Q - question

iLogic rule - check whether iProperties are overridden.

A - answer iProperties in Inventor documents allow to manually override values of Mass and Volume. These values are also used for the automatic iProperty "Density".

Overrides of true values can be useful in many cases (purchased parts, dummy parts in assemblies), but they can also be source of problems if you e.g. forget to update or replace the overridden value.

With the following simple macro you can quickly check if the iProperties "mass" and "volume" are manually overridden in the current document (IPT part):

oPartDoc = ThisApplication.ActiveDocument  
oMassProps = oPartDoc.ComponentDefinition.MassProperties  
uom = oPartDoc.ComponentDefinition.Document.UnitsOfMeasure  
voverridden = oMassProps.VolumeOverridden  
moverridden = oMassProps.MassOverridden  
voLunits = uom.GetStringFromType(uom.LengthUnits) & "^3"  
MsgBox ("MassOverridden=" & moverridden & vbTab & " [" & uom.GetStringFromValue(oMassProps.Mass,uom.MassUnits) & "]" &  
vbCrLf &  
"VolumeOverridden=" & voverridden & vbTab & " [" & uom.GetStringFromValue(oMassProps.Volume, volunits) & "]" , _  
MessageBoxIcon.Information, _  
"iProp Overrides")
