How do I generate full GDS using Encounter 2014 and osu_soc_v2.7 libraries?

Hi there, 

I am self studying some place & route with Encounter 14. My background are design and synthesis.

The library I use is from this directory. 

https://vlsiarch.ecen.okstate.edu/flows/MOSIS_SCMOS/osu_soc_v2.7/cadence/lib/

I managed to load netlist and LEF, create power ring, rail and stripes, place and route. The GDS I export doesn't contain the poly layers. 

I suppose it's caused by the LEF file is abstract module which only contains the metal layers. I dont have virtusso to use. 

Is it possible and how do I create a full gds with every layers out of Encounter alone?
