My experience was with winged nymphs made in Poseur [that's the version with the foppish Hollywood wardrobe.]. They took an eternity to open as 3Ds in Archicad.
But when i opened the 3Ds in Cinema [virtually instantly] recomposed the group of them and saved them, the group opened quickly in Archicad.
It was like a magical streamlining. In Canada's Newfoundland they catch food by "jigging the cod." I imagine this to be "jigging the code."
