Hello YGYL, and thank you for your contribution [:)]
I have added the translation to the latest versions of my 3 plugins; all of them have a new baseline version, which is 3.0.
I've made just small changes to your files:

• For 3D dimension lines and Wirings I've changed the minimum required version of Pan3dView from 1.7 to 3.0 and
• I've added the translation for some new strings in the properties files;
• for Wirings the remove point modifier keys have changed from SHIFT to CTRL+SHIFT due to a conflict with the draw on ceiling modifier, and
• I have also changed the related sentence in the help because it stated to press DEL to remove points, but in fact is CTRL+SHIFT+click;
• for 3D dimension lines I've added a sentence to the help file which explains how the new drawing aid works.

All addition/changes have been automatically translated from English, please forgive me if they aren't accurate, of course you can always propose corrections.
I've seen you credited yourself on the help buttons, I've taken one step further by crediting you on the release posts on SourceForge too.
