[0002] Construction cost refers to the process of comprehensively calculating and managing the costs of a construction project at all stages of the project, from planning and design to construction and completion. Architectural drawings are essential in construction cost work. Architectural drawings usually contain a large amount of detailed information, including floor plans, elevations, sections, detail drawings, etc., which require a cutting device to adjust the size of the drawings to a more manageable size for viewing and use on the construction site or in the office. In addition, there are many sites that need to be changed in a project, so they need to be easy to carry.
