This would only have meaning if you could import real items into Bryce for comparison. Assigning 'real world' measurement units to a model in one program won't give them meaning in another. Bryce imports every mesh (or group) with the longest dimension at 40.96 'Bryce units'. This is the case whether it's a model of a mouse or an elephant. In a thread a few below, there is a model of a cathedral (a whole compound) mentioned. This comes in at 40.96 'Bryce units' too. If one foot equals 0.4 'Bryce units', that's a pretty small big church. ;-)
