The .dwg format is useful because it is readable by more applications than the .dwf format. The .dwg format is also more portable than .dwf because the .dwg stores references to external images rather than storing the images within the .dwf file.
You can run most Draftsight commands from both the menu and the command window.
When you run SNAP from the command window, you can set the spacing of a grid. You can use this grid to help you create the point of the arrow with precision.
It does not matter where on the plot you create the arrow. You can move it, rotate it, or scale it, later if necessary.
The points you create snap to an invisible grid.
The arrow is coloured red.
The arrow is now an object you can reuse in other plots.
Because the arrow is too large for this plot, next you will reduce its size using the Scale command.
The arrow is rotated 225 degrees in an anti-clockwise direction.
