AcadX Has Been Discontinued
The AcadX ActiveX Extension Library was created to serve as a tool for use by myself in my private consulting work. Not long after it was put into use, it became clear that others could benefit from this tool as well. And so I made AcadX freely available to anyone, subject to the restriction that it be used for private use in their own work, and that they not distribute copies of it with an application, outside of their organization.
As a free resource, AcadX became extremely popular and widely used. The burden of maintaining AcadX was borne entirely by myself, and while contributions from a few who desired to distribute it and were willing to pay for support helped to some extent, it did not come close to offsetting the expense of maintenance and support.
When 2004 was released, I was faced with the significant burden of updating AcadX to run on that product. Not long after that work was started it became clear that it was going to involve much more work than I had anticipated (mainly as a result of many new defects that were caused undocumented changes and defects in the product and APIs that AcadX was dependent on). That work took over 6 months, and was done entirely at my own expense.
Once the 2004 version of AcadX was complete, I decided to offer site licenses for a fee. To date, only a handful of licenses have been sold, and it has become clear that there is no potential for recovering the expense of maintaining and updating AcadX. For this reason, I have decided that licensing AcadX for a fee is an unprofitable venture, and because of the emergence of a new programming model (the .NET API for AutoCAD 2005), the demand for AcadX is and will continue to decline.
Therefore, as of this date, I have decided to discontinue AcadX entirely. I will continue to provide whatever support I can to the handful of AcadX for AutoCAD 2004 licensees, as well.
Tony Tanzillo,
Design Automation Consulting这里的意思就是说，作者开发了将近半年时间，由于很辛苦，所以决定收费。
但交费的人太少了，没钱可赚。
再加上2005支持.net技术，作者所开发的这些功能在2005中都可以自己实现。
所以决定停止开发acadx.arx，而且也停止注册。
呵呵，一直在找，但还是得不到。有些可惜。 |
