A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes. [4] The contour interval of a contour map is the difference in elevation between successive contour lines. [5] The gradient of the function is always perpendicular to the contour ...
In a continuous-line drawing, the artist looks both at the subject and the paper, moving the medium over the paper, and creating a silhouette of the object. Like blind contour drawing, contour drawing is an artful experience that relies more on sensation than perception; it's important to be guided by instinct. [2]

Most of this information will be derived from the topographic features on the site. A contour map of this magnitude can be located from the survey engineer. Drainage problems as well as existing natural features of trees, ground cover, ground texture, and soil conditions on the site should be directly observed.
The various features shown on the map are represented by conventional signs or symbols. For example, colors can be used to indicate a classification of roads. These signs are usually explained in the margin of the map, or on a separately published characteristic sheet. [17] [18] [19] Topographic maps are also commonly called contour maps or ...

(The image plane is parallel to the y-z-plane.) The left and the far right images look more like prolonged cuboids instead of a cube. Axonometry (cavalier perspective) of a house on checked pattern paper. In order to keep the drawing simple, one should choose simple foreshortenings, for example or .
