遇到一个问题，请大家帮个忙，谢谢
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();
}
谢谢，楼上，我再研究研究
