My experience with LSM in Washington, D.C. was incredible.  It was my first experience with a large international firm.  Our focus was on commercial interiors in urban settings, mostly skyscraper lobbies, elevators, bathrooms and rooftops.  My job throughout most of these projects was to manage the 3D files in Rhino, render them in Vray and Photoshop, and to develop and correct construction documents and redlines in Microstation.
