I’m using Ultiboard v11.0 to design PCBs as I don’t like Eagle but am having some problems getting boards made by Batch PCB. If anyone is using Ultiboard can you post your settings so I don’t have to keep submitting files over and over again until I get them right? Right now the current issue is that all my layers are apparently infinitely sized. I’m not really sure how to fix this as the code clearly states that they are finite. 
I don’t know Ultiboard, but I suggest feeding your files to gerbv to give another view of what your software is producing.
