关于坐标系统

<P>各位大虾，我将cad数据load到datebase中，出现错误提示：</P>
<P>objects from polyline did not load because of error.do you want to see the object ids and the error.</P>
<P>yes后</P>
<P>the operation was attempted on an empty geometry。</P>
<P>请各位帮忙!!!!!先谢谢了</P>

<P>这个不是坐标系统的错误</P>
<P>是因为你的图层中有的记录topo关系有问题</P>

<P>谢谢，难到不是出范围了</P>
