I'm trying to control the location where a projector projects a blueprint so the contact point is in a buildable position. I always thought the grid pivot defined the projector's reference point, but the location that's coming up seems random. I tried anchoring a few armor blocks into the ground to form a column of sufficient height for the ship to clear the ground, then pasted the ship on top of the column of blocks at a convenient location on the ship's bottom. The grid pivot showed to be at the center of the first block I placed in the ground, and the grid pivot still shows to be several blocks under the point where I want the projector to project the blueprint after I removed the column of blocks. However, when I bring up the saved blueprint in the projector, the reference point is at an entirely different location that appears to be random. Is there a way to tell a blueprint, "Hey, this is the place where I want the projector to contact the grid."? Or, put another way, what am I doing wrong?
