[求助]怎样把文本文件中的坐标值转换成cad中的坐标点

<div style="FONT-SIZE: 14px;"><div style="FONT-SIZE: 14px;"><span class="viewthreadtxt">搞线路勘察经常需要根据gps坐标绘图，可是gps坐标导出来是文本格式的，怎样才能把这些数值转换到cad中去并根据这些数值生成坐标点</div><div style="FONT-SIZE: 14px;">下边是gps导出来的数据，我只列举了其中三个点，格式如下，N后边的数表示北纬多少度，E后边的数表示东京多少度。哪位高手能给编一段程序能够自己读取txt文件中的坐标值，并自动在cad中生成坐标点。<br/>Grid&nbsp; &nbsp; &nbsp; &nbsp; Lat/Lon hddd癿m.mmm'<br/>Datum&nbsp; &nbsp; &nbsp; &nbsp; WGS 84<br/><br/>Header&nbsp; &nbsp; &nbsp; &nbsp; Name&nbsp; &nbsp; &nbsp; &nbsp; Description&nbsp; &nbsp; &nbsp; &nbsp; Type&nbsp; &nbsp; &nbsp; &nbsp; Position&nbsp; &nbsp; &nbsp; &nbsp; Altitude&nbsp; &nbsp; &nbsp; &nbsp; Depth&nbsp; &nbsp; &nbsp; &nbsp; Proximity&nbsp; &nbsp; &nbsp; &nbsp; Display Mode&nbsp; &nbsp; &nbsp; &nbsp; Color&nbsp; &nbsp; &nbsp; &nbsp; Symbol&nbsp; &nbsp; &nbsp; &nbsp; Facility&nbsp; &nbsp; &nbsp; &nbsp; City&nbsp; &nbsp; &nbsp; &nbsp; State&nbsp; &nbsp; &nbsp; &nbsp; Country<br/><br/>Waypoint&nbsp; &nbsp; &nbsp; &nbsp; 0001&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; User Waypoint&nbsp; &nbsp; &nbsp; &nbsp; N38 02.632 E114 36.133&nbsp; &nbsp; &nbsp; &nbsp; 245 ft&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Symbol &amp; Name&nbsp; &nbsp; &nbsp; &nbsp; Unknown&nbsp; &nbsp; &nbsp; &nbsp; Waypoint&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <br/>Waypoint&nbsp; &nbsp; &nbsp; &nbsp; 0002&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; User Waypoint&nbsp; &nbsp; &nbsp; &nbsp; N38 02.667 E114 36.124&nbsp; &nbsp; &nbsp; &nbsp; 203 ft&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Symbol &amp; Name&nbsp; &nbsp; &nbsp; &nbsp; Unknown&nbsp; &nbsp; &nbsp; &nbsp; Waypoint&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <br/>Waypoint&nbsp; &nbsp; &nbsp; &nbsp; 0003&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; User Waypoint&nbsp; &nbsp; &nbsp; &nbsp; N38 02.667 E114 36.125&nbsp; &nbsp; &nbsp; &nbsp; 205 ft&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Symbol &amp; Name&nbsp; &nbsp; &nbsp; &nbsp; Unknown&nbsp; &nbsp; &nbsp; &nbsp; Waypoint<br/></div></span></div>

用GPS带的专用软件即可

<p>不行啊，我们的gps带的软件只能倒成txt文件，并不能实现我说的功能啊，这位兄弟你如果有这个软件麻烦传上来好吗，拜托了。</p>

<p>好像有个快速生成点坐标的下软件吧，以前用过，到网上搜搜看！</p>

其实要编这个也不是很难，不过都能导成文本格式了，在导入到Excel里编辑一下形成11436.133，3802.632 样式（逗号为半角的），可接复制到CAD里的pline命令后（命令行里）粘贴就能绘出多线了，多线的各端点就是你要的点位！

如果是数量比较大的图形的话，楼上的方法似乎速度上没有什么优势哦！有别的更好的方法吗？

<p>是啊，是啊，</p><p>excel是生成了所有点的坐标，但是数据太多，上千上万，</p><p>而且不是单一的一个动作就完成了，要不断的复制A列的，生成一条曲线，然后又复制B列生成曲线，还要选曲线线形，C列、D列，不同表格的AB列、bc列、或某个单元格、等等，非常多。</p><p>现在就是要把这些所有的动作都一口气，一个动作完成了。</p>

<p>手输吧，更快</p><p>我用excel，你拿你的数据来，一个小时给你搞定</p>
