Hello,
Maybe I've missed something really basic, but I always assumed that if you were in a sketch, you sketched according to the part coordinate system. So if you are in the Right Plane and create a line from the origin immediately to the right, it should be going in the Z direction. But its not. Until you actually place the line, the system bar at the bottom says that you are going in the X direction. See the attached picture to see what I mean.
Now what is really crazy is that once I place the line, and then select the end point, it then gives the coordinates with respect to the part.
Hope that makes sense. Is this always the way it has been?
Thanks,
Keith
