Haven't used it and have no desire to.You don't have to post the same question multiple times.

From what I saw this program originates with a company in China... making it a good fit for the OP.  But it also looks a like a reverse engineering job on AutoCAD.  How well it would play with AutoCAD is an open question.  Like a lot of these look-alikes, it would depend on how you used it.  If you could get it to do everything you needed, and you never needed to swap files back and forth with "real" AutoCAD DWG files, it might be fine.  The problems will come in when going back and forth.  That's where I'd expect a lot of issues.Just depends on what you do, what you need, and how you plan to use the program.  It might be fine in the right circumstances.  Most of us here wouldn't need it.  We already have valid Autodesk licenses.Dave.

Why do Nancy and cherry sound like the same person?Are we running an infommercial here?

Yes, I think the two of you are one in the same and are just here to promote your product.  You are a shill for the software company and have no interest in assisting people at this forum, or any other CAD forum, with their CAD related questions.Is this plain enough for you?
