How to Find and Use the GD&T-FDD Font Keyboard Chart in Excel
Question details
The user is looking for a specific keyboard mapping chart to understand which keystrokes produce which engineering symbols when using the specialized GD&T-FDD font.

- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Typing specialized engineering and geometric dimensioning symbols directly into a spreadsheet.
- Observed behavior
- Standard keys (like a semicolon) generate specialized symbols (like a diameter symbol) when the GD&T-FDD font is applied, requiring a dedicated reference chart to know the exact keystroke mapping.
Ensure that the GD&T-FDD font is properly downloaded and installed on your computer's operating system so that it successfully appears in your spreadsheet program's font dropdown list.
Consult the Official Manufacturer Keyboard Reference
The most accurate way to map keystrokes to engineering symbols for the GD&T-FDD font is by obtaining the official manufacturer's reference guide.
Because GD&T-FDD is a specialized font, its character mapping replaces standard alphabetical and punctuation keys with specific geometric symbols. Unlike standard Alt-code insertions used by other fonts, you simply type regular keys while the GD&T-FDD font is active.
For example, pressing the semicolon key might generate a diameter symbol. Accessing the official documentation ensures you do not have to guess the correct keystrokes.
Search online for the 'CyberMetrics GD&T Font Manual' or the specific manufacturer's reference guide for the GD&T-FDD font.
Download or open the PDF manual and navigate to the keyboard shortcut mapping chart section.
Open your Excel spreadsheet, select the target cell, and change the font in the Home tab's font dropdown to 'GD&T-FDD'.
Press the standard keyboard key (such as a semicolon or specific letter) as indicated by the manual's chart to display your desired engineering symbol.

Use the Built-in Insert Symbol Feature
If you do not have the keyboard chart on hand, you can manually browse and insert the symbols directly from the software's symbol menu.
Easily Insert GD&T Symbols Using WPS Office
WPS Office flawlessly supports third-party custom fonts, including specialized engineering fonts like GD&T-FDD. You can easily map your keyboard charts and visually insert engineering symbols in WPS Spreadsheet.
- 1. Open your file: Launch WPS Spreadsheet and open a new or existing workbook.
- 2. Select the specialized font: Click on the target cell, go to the Home tab, and choose the 'GD&T-FDD' font from the standard font dropdown.
- 3. Enter the symbol: Type the standard keyboard character mapped to your desired engineering symbol based on your keyboard chart.
- 4. Use the Symbol tool: Alternatively, go to the Insert tab, click 'Symbol', select the 'GD&T-FDD' font, and double-click the visual symbol to insert it instantly.

Frequently Asked Questions
Why does my GD&T font show normal letters instead of engineering symbols?
This usually happens if the font is not correctly applied to the cell or if the font isn't installed properly on your operating system. Highlight the text and ensure the font dropdown explicitly shows 'GD&T-FDD'.
Can I use standard Excel Alt codes for the GD&T-FDD font?
Generally, the GD&T-FDD font relies on direct keyboard mapping (e.g., typing a standard letter or punctuation mark) rather than Alt codes. You should check your specific font manual to see if any specific Alt codes are supported.
How do I share an Excel file using the GD&T-FDD font with others?
To ensure the engineering symbols display correctly for other users, they must also have the GD&T-FDD font installed on their devices. If they do not have the font, you can export the spreadsheet as a PDF before sharing to preserve the visual symbols.
