How To Put Superscript In AutoCAD?

Understanding Superscripts in AutoCAD

Superscripts are commonly used in various engineering and architectural documents to denote units squared, mathematical notations, and more. Properly displaying these in your designs can enhance readability and professionalism. Here’s a comprehensive guide on how to implement superscripts in AutoCAD.

Accessing the Mtext Editor

1. Start the MTEXT Command: Begin by initiating the MTEXT command. This can be done by typing MTEXT into the command line or selecting the Multiline Text tool from the toolbar.

2. Input Your Text: Type the desired text in the Mtext editor. This could be anything from measurements to chemical formulas.

Applying Superscript

1. Select the Text: Once you have typed the plain text, highlight the part you wish to change to a superscript. For example, if you’re entering "m2", you would highlight "2".

2. Utilize the Superscript Option:
   • In more recent versions of AutoCAD (including AutoCAD 2025), locate the text formatting toolbar within the Mtext editor.
   • Look for the superscript icon, which often resembles an "X" with a small number beside it (similar to ‘x²’).
   • Click this icon to convert the highlighted portion into superscript.

Using Shortcuts

An alternative to using the graphical interface is to employ keyboard shortcuts:

1. For Superscript: Hold down the Ctrl and Shift keys together, then press the + key. This will superscript the selected text.
2. For Returning to Normal Text: Simply press the shortcut again to revert back to regular text formatting.

Inserting Superscripts via Unicode

In cases where the graphical techniques are not suitable, you can insert superscripts using Unicode:

1. Identify the Character: For example, the Unicode for the squared symbol is U+00B2.
2. Input the Code: In the text editor, type the backslash followed by the Unicode (e.g., \u00B2). Press enter, and it will display as a superscript.

Creating Superscript in Specific Contexts

Example: Writing Square Meters (mm²)

1. Initiate the MTEXT Command: As before, start with the MTEXT command.
2. Type the Base Unit: Input "mm2".
3. Highlight the Superscript: Select the "2".
4. Use the ‘Stack’ Button: Look for the ‘Stack’ function, which typically has an icon resembling ‘a/b’. Click it to convert the selected number to superscript.
5. Result: You will see "mm²" displayed properly.

FAQ

Q1: Can I use AutoCAD to create other types of mathematical notation, like fractions?
A1: Yes, AutoCAD’s MTEXT editor allows for stacked fractions through the ‘Stack’ command, similar to how you would create superscripts. Simply highlight the two parts of the fraction and apply the stack option.

Q2: Are there special shortcuts for inserting other superscript characters like cubed?
A2: While the method is the same for creating cubic superscripts (³), you can directly insert it by using the respective Unicode or through similar formatting options in the MTEXT.

Q3: What if my version of AutoCAD does not support Mtext?
A3: If you’re using an older version without the Mtext feature, consider using single-line text and manually inserting superscripts as needed using available symbols or special characters. It’s advisable to upgrade to the latest version for enhanced functionality.
