In AutoCAD 2011: Tips, Tricks, and Industry Secrets, Jeff Bartels shows AutoCAD users how to become more efficient power users, reducing the amount of time it takes to accomplish a task, increasing profit margins, and strengthening marketplace competitiveness. The course covers everything from shortcuts used in geometry creation, to program customization, to real world solutions to common problems. Interface customization, block and reference management skills, and express tool usage are also covered. Exercise files are included with the course.
When it comes to creating multiline text, there's one formatting option that's very helpful, but it's not very easy to find. That's because there isn't a button for it anywhere. I'm speaking about superscript and subscript text. In this lesson we are going to learn how to create these raised and lowered characters. On my screen I have some examples of superscript text. Superscript text is typically used in formulas or exponential notation. It's also used as a shorthand method of representing position or dates. The trick to creating superscript text is using the caret key.
Let me show you what I mean. I would like to represent this number, 5,900,000, in scientific notation. So I'll double click to edit this text and I will all type 5.9 times 10 to the sixth power. To raise the six I'm going to enter a caret symbol. I will do that by pressing Shift+6. I will then drag to select this text, I'll right-click and I'll choose Stack, and then I'll click on screen to close the editor. Placing the caret after the number pushes the value up when you use the Stack option.
Technically speaking, superscript text is simply a stacked fraction without a lower value. Let's pan this up and we'll look at some example of subscript text. Subscript text is typically used in molecular formulas and algebraic equations. To create subscript text we will also use the caret key. I'm going to double click to edit this text and I will drag to select these characters. Now the molecular formula that represents propane is C3H8, three carbon atoms and eight hydrogen atoms.
Since I'd like to push these numbers down, I'm going to place the caret in front of the number. I will then drag to select the characters. I'll right-click and I'll choose Stack. Let's do the same thing for the other side. Let's do the same thing for the other number. Subscript text is simply a stacked fraction without an upper value. Knowing this, I am going to pan the drawing again and let's see if we can put these concepts together to represent the formula that will give us the area of a triangle. Let's bring back the text editor and I will select this text and I will type Area equals the base times the height divided by two.
I will then click and place a caret between my upper and lower values. I will select these, I will right click, and I will choose Stack. Now this looks pretty good. Let's take the concept a little bit farther. I am going to drag and select this text and then I will right-click and choose Stack Properties. Notice right here in the Stack Properties dialog box, I can see the upper and lower values. I also have the option of editing these values. Let's take a look at Appearance. Right now my Stack Style is set to Tolerance.
Tolerance is simply a fraction with no dividing line. I am going to open this and I will select a horizontal fraction. Note that I can also adjust the position of the fraction in relation to the text around it. I am going to leave this set as Center. Finally, I am going to open up Text size and I will set this to 100%. This will ensure that my stacked text has the same text type as the other text. And I will click OK. As you can see, by exploiting the stacked fraction feature in the text editor, we can create superscript text, subscript text, or virtually any mathematical equation we might need.
