关于openGL中调用，3ds模型的问题！我要做机器交互式仿真

我在solidworks或者用autocad绘制复杂的三维机器零件，然后转化到3dmax里面渲染，并设置好坐标，但是导出.3ds文件，在opengl里调用，但是坐标混乱了，怎么回事啊？急急啊，请高手们帮一下！
LoadT8("木地板027.bmp", g_cactus[0]); //地面帖图
m_3ds=new CLoad3DS();                            //创建3DS类
load3dobj("3ds/","x1.3DS",0);             //调入底座(A)
load3dobj("3ds/","x2.3DS",1);
load3dobj("3ds/","x3.3DS",2);
以上是我调入3d的程序
怎么组装起来呢，就是重绘后要把各个零件组装起来，因为我在3dmax里面我已经设置好坐标原点
现在：static float shoulder=0;                      //加入三个模块
    static float elbow=0;
    static float wrist=0;

glPushMatrix();
     //加入三个模块
/*glTranslatef(0.0f,0.0f,0.0f);
glRotatef(shoulder,0.0,0.0,1.0);
glPushMatrix();
    m_baiscobj->Scene(0,0,0,0,0, 0,0.1f);     //0.01f代表此时单位比例为100mm=1.0f
glPopMatrix();*/

    glTranslatef(0.0f,3.0f,0.0f);
    glRotatef(elbow,0.0,1.0,0.0);
    glPushMatrix();
m_baiscobj->Scene(1,0,0,0,0,0,0.1f);
glPopMatrix();

    glTranslatef(0.5f,1.7f,-2.0f);
    glRotatef(wrist,1.0,0.0,0.0);
    glPushMatrix();
m_baiscobj->Scene(2,0,0,0,0,0,0.1f);
大家可以看到，用坐标移动tanslate，和旋转rote等，可是一调到opengl漫游里来，原来的坐标乱了！！请求帮助
