Now you can own an AutoCAD LT clone for free. It even comes with more features than the $1000 LT.
It's called the DoubleCAD XT and it is an AutoCAD LT work-alike. But free.
Less than 60 MB in size, the DoubleCAD XT will make you feel at home, the interface is similar to that of the LT's, it even has sketch constrains unlike the LT.
If you want a version with more features they also have the DoubleCAD XT Pro for almost half the price of the XT.
You can check out DoubleCAD's website for more information & download.
