#6 shop drawing

this is one of the works of my own hands.
to build a house, surely we need a plan, both in terms of drawing sketches, cost budget plans, and others. in terms of drawing sketches, we need special precision both in terms of size and image scale. the goal is to facilitate and easily understood by the workers for the house that we plan in accordance with the design drawings.
