Drawings or pictures used to show the design effect of signs. In the process of designing signs, computer-aided design software or drawing tools are usually used to make sign renderings. These renderings can show the appearance, color, font, pattern and other design elements of the sign, helping customers or design teams to understand the final effect of the sign more intuitively. Through the sign effect diagram, the design can be confirmed, modified and communicated, so as to finally determine the best sign design scheme.
