目前支持autocad中DWG文件读写的源码除了用python写的phythonCAD，恐怕就只剩这个了。可是为什么该站要限定java和C才开通呢，其实有一些其他语言的源码也很经典啊-Currently supports autocad in the source code to read and write DWG files besides using python write phythonCAD, I am afraid the only place this has been. But why the station should be limited to java and C only to open it, in fact, have a number of other languages source code is also very classic ah
