SHX File – What is .shx file and how to open it?

Definition and Use of SHX Files

SHX files are binary files that store character shape definitions or fonts used in AutoCAD, a computer-aided design (CAD) software. These files contain pre-compiled character data that enables AutoCAD to quickly display text within drawings. By storing the character shapes in a compiled format, SHX files reduce processing time compared to loading individual character definition files for each needed shape.

SHX files are typically associated with TrueType fonts, which are widely used in both Windows and macOS operating systems. AutoCAD uses SHX files to display TrueType fonts efficiently within its drawing environment, allowing users to create clear and legible text labels, annotations, and other text elements within their designs.

Opening SHX Files Overview

SHX files, short for AutoCAD Compiled Shape Files, are binary files created by AutoCAD to store shape definitions for symbols, text, and other graphical elements. These files are used to display custom shapes and symbols within AutoCAD drawings. Due to their binary nature, SHX files cannot be directly opened using standard text editors or image viewers. To access the contents of a SHX file, specialized software or utilities are required.

Using AutoCAD

The most straightforward method to open SHX files is through AutoCAD itself. AutoCAD is the software that created the SHX files, so it has the ability to read and render them. To open a SHX file in AutoCAD, simply navigate to the “Insert” tab, select “Symbol”, and then choose the “Browse” option. Locate the target SHX file and select “Open”. AutoCAD will then display the shape of the SHX file, allowing it to be added to drawings or further modified.

SHX File Format

SHX files are compiled shape files used in AutoCAD, a commercial computer-aided design (CAD) and drafting software application. They contain pre-compiled shape definitions, including lines, arcs, circles, text characters, and symbols, which are used to render geometric shapes and symbols within AutoCAD drawings. SHX files are binary files that use a proprietary format developed by Autodesk.

By compiling shape definitions into a binary format, SHX files significantly improve the efficiency of AutoCAD’s drawing display process. When an AutoCAD drawing is displayed, the software reads the SHX file and extracts the pre-compiled shape definitions for the specific characters and symbols used in the drawing. This greatly reduces the processing time required to render the shapes, as the calculations for generating the shapes have already been performed and stored in the SHX file. Additionally, SHX files are resolution-independent, meaning they can be scaled to any size without losing their clarity or detail.
