In engineering its got to be used when making buildings and stuff like that. Even when making computers or cars, you got to make parts. Shapes and measurements are huge parts of that. Its also important for model designs. Geometry is used everywhere. Lets say you are trying to figure out the logo sign for a new business you are setting up in town. You are trying to figure out the size, shape, and where to put it on the building. Anything involving creation, such as fashion, technology, engineering, etc., uses geometry as a guide in the process of making something. I don't know if this was the answer you were looking for, but this was my understanding of the question. Hopefully this helps.
