Problem getting the Distance property in a DistanceChamfer via API

[Anonymous]

Hi there,

I am using Inventor 2018 and programming an addin in C++. I would like to access the 'Distance' property in a DistanceChamferDefPtr object but I am getting a _com_error exception.

 Snippet

ChamferFeaturePtr chamferFeature = chamferColl->GetItem(itChamfer);
if (chamferFeature == NULL)
    return;
 
ChamferDefinitionPtr chamferDef = chamferFeature->GetDefinition();
if (chamferDef->Type == kDistanceChamferDefObject) {
    DistanceChamferDefPtr distanceChamfer = chamferDef;
    if (distanceChamfer) {
        ParameterPtr distanceParam = distanceChamfer->Distance;
        double value1 = (double)distanceParam->Value;
 
        VARIANT_BOOL setBack = VARIANT_FALSE;
        setBack = distanceChamfer->CornerSetback;
        double angle = 45.000;
    }
} 

When I try to get the Distance or CornerSetback ParameterPtr is when the program raises the exception. Any clue where my problem could be located?

Regards
