There are three tools under Revise: the first two allow you to move, resize and rescale an image (referred to as a Raster). The move and resize tools are excellent for repositioning images inserted from the on-line plant database so that they fit better into the drawing layout. The rescaling option is always used in conjunction with images entered from your computer, such as property surveys. Using this tool, you can take any image and, provided you know a distance or length of a line on the image, resize the image to match the scale of the prototype you have selected. This saves valuable time when tracing the information to create the base plan.
The last tool is the Raster Editor, which is what you can use to remove images from your drawing, or to change the look of your drawing by toggling the visibility of an image on and off, or to double-check what you are tracing to ensure you have all the objects included before you remove the raster.
