Question

简单的实体布尔运算：

            MxDraw3dMakeShape make = new MxDraw3dMakeShape();
            //绘制圆球(0,0,0)球的原点,40球的半径
            MxDraw3dShape Sphere = make.DoSphere(0, 0, 0, 40);
            //绘制方块(-10, -50, -10) 方块的原点,(20,100,20)方块的长宽高
            MxDraw3dShape Box = make.DoBox(-10, -50, -10, 20,100,20);
            //进行布尔相加运算
            MxDraw3dShape ShapeAdd = make.DoAdd(Sphere, Box);
            //设置实体的颜色和材质
            ShapeAdd.Mx3dColorIndex = MxDrawX3dLib.MX_3DCOLORINDEX.Mx3dSLATEGRAY4;
            ShapeAdd.Mx3dMaterial = MxDrawX3dLib.MX_3DMATERIAL.Mx3dBRASS;
            //设置显示模式
            ShapeAdd.SetDisplayMode(1);
            //绘制得到的实体 
            axMxDrawX3d1.DrawEntity(ShapeAdd);
            //居中显示
            axMxDrawX3d1.ZoomAll();
 
            MxDraw3dShape Sphere1 = make.DoSphere(100, 0, 0, 40);
            MxDraw3dShape Box1 = make.DoBox(90, -50, -10, 20, 100, 20);
            MxDraw3dShape ShapeCut = make.DoCut(Sphere1, Box1);
            ShapeCut.Mx3dColorIndex = MxDrawX3dLib.MX_3DCOLORINDEX.Mx3dMATRABLUE;
            ShapeCut.Mx3dMaterial = MxDrawX3dLib.MX_3DMATERIAL.Mx3dBRASS;
            ShapeCut.SetDisplayMode(1);
            axMxDrawX3d1.DrawEntity(ShapeCut);
            axMxDrawX3d1.ZoomAll();

运行效果如下：
