I have a model i need to put in established xyz coordinates so the points can be located by survey. The coordinates are big numbers and the system is used for a large area that includes a power plant. To start modeling at the correct point, i drew a line from 0,0,0 using the [x,y,z] system. Then i started cutting and pasting the components to that know position. To determine the coordinates i selected label and pointed to the location. the lines drawn from the origin to a coordinate display that coordinate. using the label tool and selecting a point on the drawn geometry don't locate correctly. I have spent quite a lot of time trying to understand it. Attached is a very simplified version of what i'm trying to do. lines drawn from the origin to the corners label correctly. labels on the drawn geometry are incorrect. I can add more components if it helps.
thanks, Pat
