Flooring Take off

I am completely new to Draftsight. This is my first attempt at any drafting software. I am an estimator for a flooring company and was curious if there is a way to down load a pdf. print from my customer. Then from that pdf calculate the sf of flooring around cabinets and walls for e ach individual room. Also be able to shade certain areas and print patterns in those areas.

Thanks for the help
