RA, Fill Rectangle Absolute This command defines and fills a rectangle using absolute coordinates. Use RA to fill rectangular shapes in drawings. (To outline a rectangle using absolute coordinates, use the EA command.) RA X,Y[;] Note Parameter Format Functional Range Default X,Y coordinates current units -230 to 230 - 1 no default The RA command defines and fills a rectangle using the current pen, the current line and fill types, and absolute X,Y coordinates. The RA 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 Coordinates - Specify the corner of the rectangle that is diagonally opposite from the current pen location (the starting point of the rectangle). Coordinates are interpreted in current units: as user-units when scaling is on; as plotter units when scaling is off. The following illustration shows the current pen location in the lower-left corner and the command's X,Y coordinates in the upper-right corner. Depending on the X,Y coordinates used, these points can be in any two diagonally opposite corners. Figure 21-22Fill Rectangle Absolute EN RA, Fill Rectangle Absolute 21-39
