There are several ways to add a fill style to an object. The main method, I guess it’s the main method because it is the default setting for fill, is the AREA FILL POINT tool. This fill tool will apply a fill to a single defined area, or shape. The user selects a point, the fill point, and the fill will, well, fill until it comes to linework. If there is a square, it will fill the square. If the shape is some type of polygon, it will fill the polygon. You get the idea. This method works great for filling shapes, one at a time.
AREA FILL LINE. This method allows the user to fill multiple objects at a time. Draw a line and every object it intersects will be filled, similar to a crossing window in AutoCAD. Actually it is more like a fence line in AutoCAD.
AREA FILL WINDOW. This has two methods to it. It works just like a crossing window in AutoCAD. Drag a window from right to left to fill all shapes the window crosses. Drag a window from left to right to fill objects that are fully inside the window. These methods work great for filling objects close together with the same style.
AREA FILL FREEHAND. This method is similar to the fill line tool. The user draws a freehand polyline, essentially, having all shapes it crosses filled.
POWER FILL. I need more power Captain (said in a Scottish accent.) This tool will fill shapes that are similar, all at once! It looks for repeating areas that are bound by objects. Similar windows on the side of a building will all be filled with just one click.
There are many ways to apply a style in Impression; some give you more detailed control while others allow for speed. Choose which method suits your needs best for the task at hand.
