dxjt_toolkit

Author: bitbybit3d@163.com

dxjt_toolkit is a C++ API library, it provides applications with the capablity to:

• read a JT file (JT 8.0 - JT 10.5 format)
• write to a JT file (saved as JT 8.1 format)

Overview

Personal works, the code for libdxjt and dxjt_toolkit is not free, only open source about usage and demonstration cases.

libdxjt.dll is used to parse JT format from file content, while dxjt_toolkit will create a similar assembly organization structure like JtOpen Toolkit do.

dxjt_toolkit relies on libdxjt.dll, while libdxjt.dll relies on zlib.dll and liblzma.dll

Example
