My favorite feature of dimensioning software is that you can import in your drawings and know they are correct because it shows you the dimensions as soon as you open it. It doesn't have a lot of bells and whistles but what I like most about this program is that it is very simple and straight forward. The user interface could be better sometimes but once you get used to it, it works well. You can upload your drawing from anywhere. I am able to use it anywhere no matter where I am or if I am at my computer or using my phone.
