1. 增加COM接口，把常用的建模函数封闭成 com对象
2. 编写c#调用例子，比如创建一个衣柜，窗户等
比如，创建衣框代码如下：
axMxDrawX3d1.ShowTexturize = true;
axMxDrawX3d1.Light = true;
MxDraw3dMakeShape make = new MxDraw3dMakeShape();
//第一块
MxDraw3dShape shap = make.DoBox(0,0,0,800, 300, 15);
MxDraw3dShapeTransformation s = new MxDraw3dShapeTransformation();
MxDraw3dPoint pt = new MxDraw3dPoint();
s.scale(pt, 1.0);
MxDraw3dShapeTransformation m = new MxDraw3dShapeTransformation();
MxDraw3dVector vec = new MxDraw3dVector();
vec.x = -400;
m.Move(vec);
m.multiply(s);
shap.TransformShape(m);
MxDraw3dTexturedShape ts = make.CreateTexturedShape(shap);
ts.SetTextureFileName("K:\\MxDraw3D6.0\\Bin\\vc100d\\Test\\wood01.bmp");
ts.SetTextureMap(true);
ts.SetTextureScale(true, 1, 1);
ts.SetTextureRepeat(true, 1, 1);
ts.SetTextureOrigin(true, 0, 0);
ts.SetDisplayMode(3);
axMxDrawX3d1.DrawEntity(ts);
.......
//第七块
MxDraw3dShape shape7 = make.DoBox(0, 0, 0, 1000, 290, 15);
MxDraw3dShapeTransformation r7 = new MxDraw3dShapeTransformation();
MxDraw3dPoint ptRot7 = new MxDraw3dPoint();
ptRot7.x = 1000;
ptRot7.y = 300;
ptRot7.z = 0;
MxDraw3dVector pvRot7 = new MxDraw3dVector();
pvRot7.x = 0;
pvRot7.y = 1;
pvRot7.z = 0;
r7.Rotation(ptRot7, pvRot7, 90 * 3.14159265 / 180.0);
MxDraw3dShapeTransformation s7 = new MxDraw3dShapeTransformation();
MxDraw3dPoint ptMove7 = new MxDraw3dPoint();
ptMove7.x = 0;
ptMove7.y = 0;
ptMove7.z = 0;
s7.scale(ptMove1, 1.0);
MxDraw3dVector pvMove7 = new MxDraw3dVector();
pvMove7.x = -1000;
pvMove7.y = 0;
pvMove7.z = 0;
MxDraw3dShapeTransformation m7 = new MxDraw3dShapeTransformation();
m7.Move(pvMove7);
m7.multiply(r7);
m7.multiply(s7);
shape7.TransformShape(m7);
MxDraw3dTexturedShape ts7 = make.CreateTexturedShape(shape7);
ts7.SetTextureFileName("K:\\MxDraw3D6.0\\Bin\\vc100d\\Test\\wood01.bmp");
ts7.SetTextureMap(true);
ts7.SetTextureScale(true, 1, 1);
ts7.SetTextureRepeat(true, 1, 1);
ts7.SetTextureOrigin(true, 0, 0);
ts7.SetDisplayMode(3);
axMxDrawX3d1.DrawEntity(ts7);
axMxDrawX3d1.ZoomAll();3. 控件运行效果抓图：
