As for the final project of detailing drawing, we need to produce a series of working drawing of our design. those working drawing include: setting out plan, reflected ceiling plan, furniture plan, electric plan, section and furniture details. From this project, I learnt that the actual working drawing that i need to produces when I work as an interior designer. Which I need to use these communicate with the contractor. Its important that produce a right working drawing, if produce wrongly then will occur construction failure.
