Description

Technical Field

[0001] The utility model relates to the technical field of building design, in particular to a building design drawing device. Background Art

[0002] When designing an architecture, although the final design can be done by computer, in the process of sorting out the design ideas, most designers are more accustomed to hand-drawing design sketches. However, in the process of modifying the sketch design, the existing design drawing devices include traditional tools such as paper, pen, and ruler, which cannot record the drawing steps and the sketch modification process, making it difficult for designers to review the design drafts before and after the modification, resulting in a long architectural design cycle. To this end, we propose an architectural design drawing device that can record the drawing steps. Utility Model Content
