EN ER, Edge Rectangle Relative 21-23
ER, Edge Rectangle Relative
This command defines and outlines a rectangle using relative
coordinates. Use ER when drawing charts or schematic diagrams
that require rectangles.
ER X,Y[;]
The ER command defines and edges a rectangle using relative
coordinates and the current pen, line type, and line attributes. The
ER command includes an automatic pen down. When the command
operation is complete, the original pen location and up/down status
are restored.
z X,Y Increments — Specify the opposite corner of the rectangle
from the current pen location. The current pen location is the
starting point of the rectangle. Increments are interpreted in
current units: as user-units when scaling is on; as plotter units
when scaling is off.
Note The following illustration shows the current pen location in the lower
left corner and the command’s X,Y increment location in the upper
right corner. When drawing a rectangle, these points can be in any
two diagonally opposite corners.
