ViewEE is a software to view PCB layouts in various formats. Currently supported are Cadsoft Eagle
.kicad_pcb and gEDA
Parser and renderer are not ideal. Some problems can be fixed (pad, via shapes), some — not (I don’t have an access to the eagle font). At current stage you will definitely face problem with thru hole pad shapes, arcs, rotated elements and text. Eagle parser have best quality, Kicad renders ok and gEDA pcb parser is quite basic.
Currently only 2layer boards are supported.
Reference rendering in version 0.2.0, current version is much better.
