.... You can come back to principles later? Wow I really misread something in there, I thought you had to prepare a Principle enough times to create/affect whatever you wanted to affect/create consecutively.
That's fine then.
Second nitpick, in BIOY 101, you can create affect cubic foot per preparation, but the HD of the biostructure created is keyed of the thickness of the structure. Does this mean I could prepare the Principle 100 times and create a wall 1 foot by 1 foot by 100 foot long and key the thickness of the 100 foot length, so it would have 100HD?
