Geometry. From them, generated, such as segments, curves, surfaces, polyhedrons, etc. Representation systems can be separated into three different groups: orthogonal cylindrical projections: 1. Dihedral system. Inesem business school course in interpretation of plans more information 2. Bounded system. 3. Axonometric system. Oblique cylindrical projections: 4. Knight perspective system. Conical projections: 5. Conical system. Representation of planes 1: dihedral or monge system the dihedral system is also known as that of monge, a french mathematician (xviii-xix), compiler and guide of descriptive geometry.
This system is based on orthogonal cylindrical projections on two planes that form an angle of 90ยบ. These two planes are called the vertical and the e commerce photo editing horizontal. The intersecting line is called the ground line. The horizontal plane collapses on the vertical, or vice versa, taking the ground line as a hinge. The two planes are converted into one. These two projections give us the plan and the elevation. The profile gives us the projection on a plane perpendicular to the ground line, which gives us another projection, the profis based on orthogonal projections on a plane. The projection plane (picture plane, horizontal, reference, main), is the only one used in this system.
This system is mainly used in topography or topographic drawing , whose most direct applications are: path layout, embankments, clearing...; and in general the lifting of a topographic map. In architecture they are used to calculate roof slopes. Representation of plans 3: axonometric system the axonometric system is based on orthogonal cylindrical projections, on a main plane and three auxiliary ones. The planes make up a trirectangular trihedron, limited by the x, y and z axes. Its main objective is to provide as complete a view of an object as possible.
