IFC export scale issues in AC15

Anonymous
Not applicable
I am having trouble when exporting my model as an IFC. When I bring the IFC into another program (Tekla Structures, Tekla BIMsight, Solibri), the scale is multiplied by a factor of 3.658.

I wasn't having trouble exporting IFC files in AC14, but once i installed AC15 this started happening.

Is there some kind of export setting in AC that I need to change to fix this?

Can it be an inch/feet/Meter problem?
Have you checked the Translator settings?

I don't think it is an inch/feet/meter problem because the conversion factor doesn't work for any situation. These are my Export IFC Model Units:

Length Unit: Inch
Angle Unit: Degree
Area Unit: Square Foot
Volumne Unit: Cubic Foot
