http://www.zwsoft.com/forum/viewthread.php?tid=1962 Hello, Some weeks ago I downloaded ZWcad 2012 and was able to install my autolisp program within hours. It's great, it's what I was waiting for for almost ten years now. Today I try ZW3D, which is a 2011 version. Actually I was thinking to adapt my program from 2D to 3D. But ZW3D seems to be a totally different program than the 2D: -nothing to do with 2D interface -no easy way to load user menu -no way to load (auto)lisp programm Am I right saying that ? Is there any possibility to write and run specific programm within ZW3D ? maurice 2012-01-28 05:24:30 http://www.zwsoft.com/forum/viewthread.php?tid=1962&pid=14237 Hi, Maurice, Just FYI, if you would like to develop any application in ZW3D, you should use C++, there is the built-in library located in the installation folder such as X:\Program Files (x86)\ZWSOFT\ZW3D 2012 Eng\api. colinchuang2008 2012-02-03 10:10:09 http://www.zwsoft.com/forum/viewthread.php?tid=1962&pid=14196 [b]Reply [url=http://www.zwsoft.com/forum/redirect.php?goto=findpost&pid=14191&ptid=1962]2#[/url] [i]tmarkoski[/i] [/b] Thank you for the answer. It's clear. I'll stick with the 2D and forget about 3D maurice 2012-01-28 22:01:38 http://www.zwsoft.com/forum/viewthread.php?tid=1962&pid=14191 AutoLISP and VBA are not supported in ZW3D. ZW3D still supports the old VX Macro language so it is possible to automate some design tasks. tmarkoski 2012-01-28 05:40:46
