Gerber lines in ground plane

I finally found a solution to this problem.

Well I don't know if I can really call this a solution because I had to switch software.

Before to switch I tried multiples cam files, I exported from Windows and Linux (Ubuntu). I started a topic in the autodesk forum. Some of the users were able to replicate my problem and others not. The Autodesk representatives were not interested in helping me, so I still don't know what is really happening. They answered but there is not a solution yet (01/2018) (see autodesk topic)

I must say that in Viewmate the problem wasn't present, but my manufacturer wasn't using that software, so wasn't a solution for me. Now with KiCAD the gerber files looks good in any platform or viewer.

My solution was download KiCAD, at this moment the last version is: 4.0.7, and import the brd file.

The steps to open the brd file are:

1. open the pcbnew.exe file in the bin folder located in C:\Program Files\KiCad\ (I don't know how this works in the others platforms)

You have to do it that way, otherwise you won't have the open file option.

2. Go to File > Open File and select XML PCB File from Eagle ver.6.x (*.brd)

When you select your file it will be imported in KiCAD. In my case I had to make the ground planes (zones) again, but I solved that in less than 5 minutes.
