有个天大的难题，考验高手的时候到了

萧秋水

是的我也有过，从PROE转到2004CAD中会出现这个问题！请教解决办法

我没试过

真实的谎言

我也没有见过呀,很感兴趣!

應該是小段大徑之圓弧出現該情況，該問題的出現除了與proe本身精度設置有關，還與不同格式文件的轉換會出現偏差有關（如同*.igs格式文件轉入proe會出現破孔是類似的道理），我們也不必為此而大驚小怪。所以先改proe之Accuracy試試看，若無效果那只有在autocad里手工改了！！ok??

从proe里的drawing图转到autocad时，有时圆弧或曲线会变成直线（我在autocad里regen后也一样）？为什么？我没找到解决方法，有谁能告诉我？？[em00][em00]

我帮他传上图片
大家给看看
我也没碰见过这现象

有时是会成为n段直线，精度是一方面，有时也可能你的圆弧是空间线，经过投影当然不会是一条弧了。

先谢谢兄弟
我做的是平面内的curve线，没做投影，

你的怎么解决的？？？

ease

这种问题还是显示问题,你打印下,肯定不是直线,我也常见到这问题,我就是这样处理的,不知是否正确.

上传个档上来看看

我也碰到过，当时是一小段大径圆弧变成直线，跟28楼兄弟说的一样。

lisi780025

有，有时给线割图遇到了，好烦人的

我也遇到过，至今未解决呢

没有的事

kfkfyzh

可能是精确度问题。我同意30楼兄弟看法
