How Do I Create a SHX File in AutoCAD?

by

AutoCAD is a powerful software used by architects, engineers, and designers to create precise and detailed drawings. One of the key features of AutoCAD is the ability to use custom fonts for text and annotations.

These custom fonts are stored in SHX files. In this tutorial, we will explore how to create a SHX file in AutoCAD.

What is an SHX file?

Before we dive into creating an SHX file, let’s understand what it actually is. An SHX (compiled shape) file is a specially formatted file that contains information about custom fonts used in AutoCAD. It stores the shape definitions, line styles, and other attributes of the font.

Why create a custom SHX file?

AutoCAD provides a wide range of standard fonts that can be used for text and annotations in drawings. However, there may be situations where you need to use a specific font that is not available in the standard library. In such cases, creating a custom SHX file allows you to use any TrueType or OpenType font of your choice.

Steps to create an SHX file:

Now let’s get into the steps involved in creating an SHX file:

  1. Create or select a font: The first step is to choose a TrueType or OpenType font that you want to use in AutoCAD. You can either create your own custom font using third-party software or select an existing font from your system.
  2. Convert the font: Once you have chosen the font, you need to convert it into a format compatible with AutoCAD. To do this, you can use specialized tools like ‘FontCreator’ or ‘AutoCAD SHX Font Creator’. These tools allow you to convert TrueType or OpenType fonts into the SHX format.
  3. Create the shape definitions: After converting the font, you need to define the shapes for each character. This involves drawing the outlines or contours of each letter, number, and symbol in your chosen font. AutoCAD provides various tools and commands to create these shapes accurately.
  4. Compile the SHX file: Once you have defined all the shape definitions, you need to compile them into a single SHX file. AutoCAD has a built-in tool called ‘Compile Shape’ that allows you to compile and save your custom font as an SHX file.
  5. Load the SHX file: After compiling the SHX file, you can load it into AutoCAD using the ‘Shape File’ option in the ‘Text Style’ dialog box. Once loaded, you can use your custom font for text and annotations in your drawings.

Tips for creating an effective custom SHX file:

Creating a custom SHX file requires attention to detail and precision. Here are some tips to help you create an effective custom font:

  • Simplify shapes: Keep your shapes simple and clean. Avoid overly complex contours that may cause issues during conversion or display incorrectly in AutoCAD.
  • Consistent stroke width: Maintain a consistent stroke width throughout your custom font to ensure uniformity in appearance.
  • Avoid overlaps: Ensure that there are no overlapping lines or shapes within each character. Overlaps can lead to rendering issues and inaccuracies in text display.
  • Test and refine: After creating your custom SHX file, test it thoroughly in different scenarios to ensure it behaves as expected. Make necessary adjustments or refinements to improve the readability and appearance of your font.

Conclusion

Creating a custom SHX file in AutoCAD allows you to use any TrueType or OpenType font of your choice for text and annotations. By following the steps outlined in this tutorial and adhering to best practices, you can create an effective custom font that enhances the visual appeal of your AutoCAD drawings.
