What is GkLevel?
Surely you have a block with attributes that represent an elevation label. Probably you insert the
block, and manualy edit the attribute to reflect the distance from a base plane (ref. 0.00).
Or maybe you use a dimension object with custom arrow, or you have a lisp or vba routine to
"automaticaly" calculate the value.
Well, GkLevel do that. But as a custom object. You no longer need to manualy calculate the
attribute value, or check for the dimension origin plane when you move or stretch it. The GkLevel
object always reflects the true value from its origin/base plane, even as you move or stretch it.
How it works?
Draw your base line as you always do, and simply execute the command LevelAdd and place it.
By default all new objects have the origin point at y=0.00 (the WCS origin), and the orientation
is horizontal (along the x axis).
