今天好像搞明白了，ecilpse的python開發環境如何使用的問題。基本步驟如下

1）打開ecilpse和UGNX

2）啟動ecilpse的調試服務（debug server）并打開需要測試的腳本

3）在UGNX中運行腳本回放功能（運行步驟2的腳本），這時UGNX界面會出現類似卡住的現象（應該實在等待ecilpse命令）

4）切換到ecilpse，然后就可以單步調試運行了，UG界面就會根據腳本內容變化了。

個人感覺這個ecilpse的開發環境最大的好處，可以進行命令的補全。程序調試方面感覺并沒有那么順手，可能是我用的不熟練的原因吧。

下面來一段測試代碼吧，畫兩個點，然后兩點連成直線，希望對想學習UG-python開發的有用

associativeLineBuilder1.Destroy()
#print("this is nx test")

mysession.LogFile.WriteLine(what)
mysession.ListingWindow.Open()
mysession.ListingWindow.WriteFullline(what)
