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.

最早的版本v2.0.5：https://sourceforge.net/projects/qcadbin-win/

QCAD v2.2.2.1 最后一个v2.x系列的版本

QCAD v3.0.9.0 从v3.x开始使用ECMA Script interface

qcad的dxf读取在\src\io\dxf\RDxfImporter.cpp
void RDxfImporter::endEntity()
{
QSharedPointer<RSplineEntity> entity(new RSplineEntity(document, RSplineData(spline)));
importEntity(entity);
}

qcad的样条曲线的绘图在/src/core/RPainterPath.cpp
void RPainterPath::addSpline(const RSpline& spline) {
int degree = spline.getDegree();
if (degree<=3) {
moveTo(spline.getStartPoint());
}

QList<RSpline> list = spline.getBezierSegments();

for (int i=0; i<list.count(); i++) {
QList<RVector> cps = list[i].getControlPoints();
// very rare splines of degree >= 4:
if ((cps.size()>=5 && degree==cps.size()-1)) {
QList<QSharedPointer<RShape> > segments = spline.getExploded(16);
for (int k=0; k<segments.length(); k++) {
QSharedPointer<RLine> l = segments[k].dynamicCast<RLine>();
if (k==0) {
moveTo(l->getStartPoint());
}
lineTo(l->getEndPoint());
}
}
else if (cps.size()==4 && degree==3) {
cubicTo(cps[1], cps[2], cps[3]);
}
else if (cps.size()==3 && degree==2) {
quadTo(cps[1], cps[2]);
}
else if (cps.size()==2 && degree==1) {
lineTo(cps[1]);
}
else {
qWarning() << "RPainterPath::addSpline: invalid bezier segment: " << list[i];
continue;
}
}
}

//\src\core\RPainterPath.h

QPainterPath::cubicTo(ctrlPt1x, ctrlPt1y, ctrlPt2x, ctrlPt2y, endPtx, endPty);
}

//QPainterPath源码来自Qt官方\Qt\Qt5.12.7\5.12.7\Src\qtbase\src\gui\painting

//cubicTo和quadTo都是用来实现贝塞尔曲线的，那有什么不一样呢？
官方是这么说的：
Same as cubicTo, but the coordinates are considered relative to the current point on this contour.
说白了，就是多了一个控制点而已。

2、LibreCAD

LibreCAD 是一款开源免费的 2D CAD 制图软件，原名为 CADuntu 。它是基于社区版本 QCad 构建，并利用 Qt4 进行了重构，原生支持 Mac OSX, Windows 和 Linux 。它提供了基于 GPL 协议的读取/修改/创建 CAD 文件 (.dxf ) 方案。

LibreCAD最早源自QCad的老版本，v2.0.5，using mingw-5.1.4 and qt-3.3.x-p8.

SoftPLC, IEC 61131-3
按照工业控制领域常用的IEC61131-3标准来看，工业控制领域程序语言被分为了两大类五种语言，两大类是指图形化编程和代码编程，图形化编程中有Ladder（梯形图），FBD（Function Block Diagram，功能块图）和SFC（Sequential Function Chart，序列功能表），而代码编程有IL（Instruction List，指令集）和ST（Structured Text，结构化文本）。

几个著名的开源项目：

PLCEdit：完全按照IEC61131标准开发，所有五种语言均支持，使用Python开发，故可以做到跨平台。
Beremiz：一套完整的开源PLC解决方案，不过放在这里主要是因为它不但使用了上面说的PLCEdit，同时还对其进行了增强，使得其增加了重要的在线调试功能。推荐！！！
SoapBox Snap：使用C#+WPF开发的，仅支持梯形图一种语言，不过却已经支持了在线调试功能，含模拟器。
