我想画一个三维空间的线框，类似长方体的12条边组成的一个空间盒子，现在我已知该盒子的8个顶点坐标，请问操作才能画出该空间盒子，请大家指点，谢谢

简单的写一下.取其中一个面的四点,厚度取四点以外的点到这个平面距离

AcDbObjectId AddEntity(AcDbEntity * pEnt)
{
 AcDbBlockTable *pBlockTable = NULL;
    acdbHostApplicationServices()->workingDatabase()
        ->getSymbolTable(pBlockTable, AcDb::kForRead);
 assert(pBlockTable);
    AcDbBlockTableRecord *pBlockTableRecord = NULL;
    pBlockTable->getAt(ACDB_MODEL_SPACE, pBlockTableRecord,
        AcDb::kForWrite);
 assert(pBlockTableRecord);
    pBlockTable->close();

    AcDbObjectId lineId;
    pBlockTableRecord->appendAcDbEntity(lineId, pEnt);

    pBlockTableRecord->close();
 return lineId;
}

void test()
{
 AcGePoint3d pt1(0,0,0);
 AcGePoint3d pt2(100,0,0);
 AcGePoint3d pt3(0,100,0);
 AcGePoint3d pt4(100,100,0);

 AcDbSolid *sold = new AcDbSolid(pt1,pt2,pt3,pt4);
 sold->setThickness(100);
 AddEntity(sold);
 sold->close(); 
}
