Shapes, forms, and angled curves, all convey a feeling, or a mood to architectural illustration - conveying a feeling. The sharper edges of a building will cause one feel, as angled curves cause another, more of a softness. An architectural illustration tells the story from beginning to end. As the pages are turned to reveal each of the drawings, the story takes shape until the ending is revealed.
Materials also come into play. They form ideas in the mind, and the mood follows. Wood is soft and warm. Brick is uniform and serious. And stucco is uneven, uncertain, and the final color of it will add another sense.
Stone is sometimes uneven all over a building. Although it needs to be matched, so that angles can look like they fit together, they are not so uniform. There is much variation, and a lot to look at and take in with raw stone in the architecture.
The height of a building states its grandeur. As it towers over us, we have the feeling that it sees all, perhaps knows all. There is also a desire that one gets, to get to the top, to see what it sees.
Conical shapes of roofs convey a feeling of smooth, connected architecture. These are used in certain elegant building and home styles, and have a more subtle feel to them than straight lines of a flat roof. There are also very decorative edges to trim and some framework that adds the whimsical feel.
Architectural illustration - conveying a feeling is an art unlike any other. It shows the inside of the creation, as well as the outside. When all of the illustrations are put together, they form a complete project. And the completed building will tell a story in every section of it.
