Video: Scaling elements

If you have ever used a Copy Machine to make enlargements or reductions of images, you are already familiar with the concept of Scale. Just like we can make our images larger or smaller by using Copy Machine, we can make our geometry larger or smaller, by using the Scale command. On my screen, I have a drawing of three chairs. Let's reduce this chair on the left down to half its current size. To do that I will use the Scale command. Scale is located in the Modify Panel of the Ribbon. After I launch the command, I will select the objects I'd like to resize and then I will right-click.

Scaling elements

If you have ever used a Copy Machine to make enlargements or reductions of images, you are already familiar with the concept of Scale. Just like we can make our images larger or smaller by using Copy Machine, we can make our geometry larger or smaller, by using the Scale command. On my screen, I have a drawing of three chairs. Let's reduce this chair on the left down to half its current size. To do that I will use the Scale command. Scale is located in the Modify Panel of the Ribbon. After I launch the command, I will select the objects I'd like to resize and then I will right-click.

Next, I will select my Base Point. The Base Point is the point about which my part is going to get larger or smaller. I am going to select the end point right here, and notice as I drag my Cursor, I get the Rubberband effect, at this point I could free pick a point on screen to resize this geometry, or I could enter a value. Now the Default value is 1, and 1 represents no change. it's a one-to-one scale. To make this geometry half as big, I am going to use a Scale Factor of 0.5 and I will hit Enter.

Let's make another change. This time I am going to make this chair on the right, twice as big as its current size. To do that I will press the Spacebar to re-launch the Scale command, I will then select the objects I'd like to resize and right-click and then I will choose my Base Point, I am going to select the end point right here this time. Notice that the Base Point is the only part of the object that doesn't move. By choosing my Base Point at the end of this leg, I can ensure that my chair will always remain sitting on this horizontal line.

Now to make this chair twice as big, I am going to use a Scale Factor of 2 and I will hit Enter. As you can see the Scale command can make quick work out of design changes. The Scale command also comes in handy, if we have trouble with our drawing units. Let's look at an example. I am going to close this drawing. I won't save changes and then I will move up and click the Open icon, we will look inside the Exercise Files folder and it will go inside the chapter_09 directory and I'd like to open these two drawings, I will select racquet and then I will hold my Shift key and I will select court, and then I will click Open.

This opens both drawings in my interface and now that they are both open, I'd like to view them side-by-side. To do that I will click the View tab, then I will come down to the Windows Panel and I will select Tile Vertically. Alright, let's clean up our screen a little bit. Currently the focus is on this drawing on the left. So I am going to pan this over and center it a little bit better, then I will click in this Window to put the focus over here. I will zoom out a little bit and I will pan this drawing over.

Now this drawing on the right represents a standard tennis court and this drawing was created such that each unit equals one foot. Let's verify that quickly. I will open up the Application Menu, I will come over to Drawing Utilities and I will select Units. We can see that right there. Each unit equals a foot. Let's click OK. Now I will click in this drawing on the left. We will take a look at this one. This drawing represents a standard tennis racquet and this drawing was created such that each unit equals one inch.

Once again we will verify that quickly, we can see that right there. I am going to click to select this geometry and then I will click-and-hold on a highlighted portion and I will drag this into the other drawing and notice the problem. The tennis racquet is huge. AutoCAD only sees units. In this drawing the racquet measured 26, well that 26 represented 26 inches. When the racquet came over it still measures 26, except in this drawing it's 26 feet which is 12 times larger than it needs to be.

To correct this geometry, I am going to use the Scale command. So I am going to jump back to the Home tab, I will launch Scale and I will select my racquet and right-click. I will use the End Point down here for my Base Point and for my Scale Factor, I am going to type 1 over 12, and I will hit Enter. Then I will launch the Move command and I will select my racquet and right-click, I will pick it up from any end point and then I will zoom over on the right side of the drawing because I have another racquet over here and I will click and place my scaled racquet right next to it.

And as you can see the geometry is now appropriately sized for this drawing. Whether we need to resize our entities as part of a design change or to correct the difference in drawing units we can accurately make our geometry larger or smaller by using the Scale command.
