The XYZ origin is causing quite a bit of trouble when assembling blueprinted arms. Here is what happens:
I build an arm in creative mode. Using LCDs in game I write instructions on building the arm since you cant print multigrid arm in survival. I build it in survival and it doesnt work because the origin of axis orientation is not the same in survival as it was in creative mode.

How do I get around this?
In creative I build the arm on rotor head and save blueprint. When buidling in survival I set the projector on rotor head which is going to align origin axis orientation same as it was in creative for the arm to work. building a rotor and building arm on rotor head sets the axis orientation of a grid.

Proposal:
I work as machinist and I can tell you many 5axis CNC machines have the option to rotate origin axes orientation:
Rotate origin around Z axis
Rotate origin around X axis
Rotate origin around Y axis
usualy in this specific order, but this would be mind boggling for general users of SE

I wish you could insert command for this so I dont have to do the rotor head trick or manually change all axes in in variables...
OR
Use arm controller as reference for setting the axis orientation.

What are your thoughts about this?
Is there maybe this feature implemented but I just havent seen it?
