I am trying to create an extremely large area for mining tunnels.  I can put in my working points at the correct x,y locations but as soon as I try to insert a 3D sketch line on any plane I get this error.  Anyone know what the limits are?  My points can be over 250' to 300' apart.  I am running SW2015.

This shows a point location in x,y.  Then the error below that when I try to put in a 3D line.
