I'm trying to get a grasp on entering objects in parallel views but I am confused about something that I would think would be pretty simple process. Lets say that I want to enter a 3D line from the front view using absolute cartesian and I use 0,0 as my starting point. Why does Dcad start the 3d line somewhere other that absolute zero? When I am in plan view that's the point that is always used so why would it be any different in parallel views.

Thank you,

Can anyone shed some light please or tell me where in the manual this is explained? I'd really appreciate some insight.

I've never understood how 3D lines work, sorry

Thanks for responding Josh. I'm not interested in the 3D line itself. We could be talking about locating any 3D object. What I am trying to get at is that you would think, regardless of the parallel view, that the 0 X-point and the 0 Y-point would be the same location as it is in an ortho view. But when you go the front or a left view and input an object starting at 0,0 using absolute cartesian it starts the object at some random point in space. That's where I need the help. I was hoping that maybe Mark or one of the Dcad guys would respond at some point.
