I have been waiting on a cad app for the ipad. I looked at some apps out there but the reviews seem to be low on all of them. I saw this app for the iphone and they said they were working on one for the ipad and it used dfx files so I am thinking great. So.... I bought the app. I will say up front that they didn't lie about their app's functions. They said it would replace paper prints in the field however once I got it I found it didn't show dimenions so that was a killer for me, and most others I would think. You have to click on a line to get the sizes and if there isn't a line where you want an overall size you have to add it up.... hard sometimes. I gave the app 3 stars for a rating stating if it done dimenions it would be 5 stars. Did I do wrong on the rating? I don't want to cause developers to turn away and they didn't lie about their product. I also don't want to miss lead anyone looking to buy an app. What do you think???
