Elaine Kim wrote: Im an Interior Designer at the Library of Congress. I use Microsoft with Software called Intergraph. I do space planning for the Library staff and also for public spaces in the Library, using a Computer-aided Design and Drafting system (CADD). I used to spend a lot of time on the drawing board with parallel bars to draw and to plan out office spaces, furniture, and electrical and telephone outlet locations. Now I use the CADD system to do all the drawings. I also use it to specify all the furniture items to be ordered. The project scheduling I also do with my computer. For printing out these drawings I use 8 1/2 x 11 and 11x17 paper size. I can also use 36 X 30 or even longer paper for drawings using a plotter.
