SHX file extension - AutoCAD shape compiled data

What is shx file? How to open shx files?

File type specification:

3d graphics, CAD-CAM-CAE file type icon 3d graphics, CAD-CAM-CAE file type

shx file icon: shx filetype icon

File extension shx is associated with AutoCAD, a CAD development platform, developed and sold by Autodesk, Inc.

A .shx file contains compiled shape data (building blocks, fonts) in form of  the machine language compiled version of an shp file.

It loads much faster than an ASCII file, and all shape files are compiled for use with AutoCAD.

All the vector fonts used by AutoCAD (romans, txt, and so on) in CAD projects are compiled shape files with names like romans.shx.

AutoCAD supports Type 1 PostScript fonts (pfb) and TrueType fonts (ttf) and it is able to transform them to compiled shapes.

OpenType fonts (otf and sometimes stored as ttf) are not supported.
