Techniques for Inserting the Plus or Minus Symbol

To add a plus or minus sign (±) in AutoCAD, follow these detailed steps:

  1. Access the Text Window: Begin by opening the text editing window where you want to insert the symbol.

  2. Right-Click to Access Symbols: Place your cursor in the text window. A right-click will bring up a context menu.

  3. Select ‘Symbol’: In the context menu, look for an option labeled “Symbol.” This section contains a variety of commonly used symbols.

Alternative Methods for Inserting the Symbol

For those who prefer using keyboard shortcuts:

  1. Using ALT Codes: Position your cursor where the Plus/Minus symbol is needed. Hold down the ALT key, and while doing so, type 0177 using the numeric keypad. Release the ALT key, and the symbol will be inserted.

  2. Character Map: If you cannot find the symbol directly in AutoCAD, consider using the Character Map application available on your computer. Open Character Map, search for the Plus/Minus symbol, copy it, and then paste it into your AutoCAD text window.

Inserting Various Symbols in AutoCAD

Beyond the Plus/Minus symbol, you may also need to insert other symbols such as electrical symbols or icons for drawings.

  1. Using the Ribbon Panel: Navigate to the ‘View’ tab in the Ribbon panel and select the ‘Palettes’ section. Here, you can access various symbol palettes.

  2. Keyboard Shortcut for Palettes: A convenient way to access symbol palettes is by pressing CTRL + 3.

  3. Icon Menu for Electrical Components: If you’re working with electrical designs:
    • Go to the ‘Schematic’ tab and select the ‘Insert Components’ pane.
    • Open the ‘Icon Menu’ to browse for electrical symbols.
    • Select the desired symbol, which will then follow your cursor for easy placement within the drawing.

Creating Custom Symbols in AutoCAD

If you need a specific symbol that doesn’t exist in the standard library, consider building a custom one.

  1. Open Symbol Builder: From the Schematic tab, access the ‘Other Tools’ panel and find the ‘Symbol Builder’ option.

  2. Setting Up Symbol Properties: In the Symbol Builder menu, you can choose various attributes, templates, and types needed for your custom symbol.

  3. Finalize Your Symbol: After making your selections, click OK to enter the block editor. You can design and save your custom symbol here.
