3、PythonOCC

Python wrapper for Open CASCADE Technology.

4、cadquery

CadQuery2.0是pythonocc的高级封装库，使用了Qt语言作为界面语言，是一款正在起步的命令行建模软件，由于pythonocc的使命在于封装opencascade而非关注界面，那么对于有界面需求的开发人员，便可以好好关注一下cadquery。

5、OpenShapefactory

OpenShapefactory is a Qt-based Geometry Factory that provides a single-point of entry to the most of OCCT geometrical operations.It is a Middle-Man between you, OpenCascade and QT, it serves as a Geometry Factory wrapping OpenCascade, and providing a single-point of entry to the creation of most geometrical operations.

7、mayo

https://github.com/fougue/mayo -- 3D viewer based on OpenCascade，Support of STEP/IGES assemblies (colors and tree structure)

https://github.com/cbernardo/libIGES -- IGES解析

编译源码之前，需要在mayo源工程的opencascade.pri文件手动添加OpenCascade路径：

# Declare pure QMake variables out of OCC envvars

COMMON_PATH = "D:/My Resources/OpenCASCADE-7.5.0-vc14-64/opencascade-7.5.0"#注意斜杆的方向;引号;

CASCADE_INC_DIR = $${COMMON_PATH}/inc

CASCADE_LIB_DIR = $${COMMON_PATH}/win64/vc14/lib

CASCADE_BIN_DIR = $${COMMON_PATH}/win64/vc14/bin

CASCADE_SRC_DIR = $${COMMON_PATH}/src
