TYPES OF PLANS OF THE ORTHOGONAL PROJECTION.
-. Horizontal plane parallel to the horizontal plane of projection and perpendicular to the vertical plane of projection. -.
MAP PIE. Perpendicular to the plane horizontal projection and vertical projection plane at an angle either. -.
Frontal plane: parallel to the vertical plane of projection and perpendicular to the horizontal plane of projection. -.
MAP PROFILE: parallel to the plane side of projection and perpendicular to the vertical and horizontal projection. -.
FLAT LINE PARALLEL TO THE GROUND: is oblique to the vertical and horizontal projection and their traces are parallel to the ground line and is perpendicular to the plane side of projection.
These projections have the advantage of the orthogonal projections as well as accurate and artistic perspective, clearly and quickly give a full picture of the object they represent and also the possibility to directly determine its size, thanks to a simple rule of interpretation of object which shows the object in three dimensions: height width and depth.
This procedure is based on a combination of three axes of direction, intersecting angles to each other, forming a rectangle trihedral angle, these three axes are the directions of width, length and height, from a certain point. The dimensions of the object that we represent are placed on guidelines. TYPES

ISOMETRIC: If the scales for the three axes are equal, have the same inclination, which is 120 degrees, and three dimensions are the same too. the axis ratio is: OX = 1; OY = 1; OZ = 1.

ORTHOGONAL PROJECTION
This system will can represent an object in three dimensions, horizontal, vertical and lateral plane, a plane that has only two dimensions.
This involves projecting the object perpendicular to the planes of a dihedral rectum. In this way we obtain a partial representation on each level and relating both projections, we get the total representation of the object.
to represent any object in orthogonal projection should be taken into account:
-. The objects to be projected is placed between the plane and the observer. -.
All points, lines and surfaces opposite to the projection plane are represented as bold and visible continuous. -.
On the projection plane are projected in real size, straight and flat surfaces, located in parallel to the plane of projection. -.
When a line is perpendicular to a plane of projection, its projection on this plane is a point. -.
Cota is the separation distance of the object with the vertical projection plane. Is projected onto the horizontal projection plane. -.
Flight: the height of a point, line or area on the horizontal plane. Is projected onto the vertical projection plane. -.
Draw a line: the point of intersection of the line with any of the planes of projection. The traces can be horizontal, vertical and lateral. -.
Trace of a plane is the horizontal, vertical or lateral, which is formed when a plane touches any projection planes.

In mathematics a multiset (also called a pocket or bag, in the original) differs from a set in which each member of it has an associated multiplicity (a natural number) indicating how often the item is a member of the group, for example, in the multiset {a, a, b, b, b, c}, the multiplicities members a, b and c are 2, 3 and 1, respectively. Formal definition
In set theory, a multiset is defined as the pair (A, m) where A is a set and m: A → N is an application of A to N (positive integers). A is called the underlying set of elements. For each to A, the multiplicity of a is the number m (a).
is common to write the function m as a set of ordered pairs {(a, m (a)): a ∈ A}. Since this is, without doubt, the definition (using set theory) of the function m. For example:
• The multiset written as {a, b, b} is defined as {(a, 1), (b, 2)}
• The next {a, a, b}, in turn, is defined as {(a, 2), (b, 1)}, and
• Finally, the multiset {a, b} is defined as {( a, 1), (b, 1)}.
If the set A is finite, the size or length of the multiset (A, m) is the sum of all multiplicities for each element of A:
A submulticonjunto (B, n) of the multiset (A, m) is a subset B ⊆ A and an application n: B → N such that n (a) ≤ m (a).

Descriptive Geometry is the science that aims to study the extent considered under its three dimensions: line, surface and volume. Descriptive Geometry is for the drawing that the grammar for a language.
PROJECTION: is a graphical representation, by whatever method of representing an object, such as we see it. The points of intersection between the plane and rays projection from the point of observation and go through the different points of view, are the projection of the object.
In any projection involves three elements:
- The surface of projection screen, flat box, etc.
1 .- Projection
The plans are named with Greek letters a, b, c, etc.
If two planes perpendicular to each cut are called dihedral angle, if there are three perpendicular planes which intersect or coincide at the same point, forming the trihedral angle. If more than three planes which coincide at one point, form the polyhedral angle.
projection planes can be infinite, but there are three major.
So far we have studied the known Plane Geometry. Then study what is the geometry, which is primarily intended to teach and must be represented in a flat projection on a three-dimensional object that can be derived from its shape, dimensions and elements that constitute it.
Descriptive Geometry is the science that aims to study the extent considered under its three dimensions: line, surface and volume. Descriptive Geometry is for the drawing that the grammar for a language.
PROJECTION: is a graphical representation, by whatever method of representing an object, such as we see it. The points of intersection between the plane and rays projection from the point of observation and go through the different points of view, are the projection of the object.
In any projection involves three elements:
- The point of observation, eye, light source or point of view. From the vantage point of projection rays are emitted, which passes through all the points of the object, penetrating the surface projection (projection of the object).
- The object being observed.
- The surface of projection screen, flat box, etc.
A. TYPES OF PROYCCIÓN.
By varying the point of observation:
By varying the point of observation:
1 .- Conic projection: when the observation point is in the finite (or relatively close to the object projected
), all projection rays start from the same point observation and form a kind of cone.
), all projection rays start from the same point observation and form a kind of cone. 2 .- Cylindrical Projection: is one in which the viewpoint is at infinity, all projection rays are parallel to each other and the cone obtained in the previous case
becomes a cylinder.
becomes a cylinder.
varying the projection surface:
1 .- Projection
Oblique projection when the rays of an angle either, other than 90 degrees with the plane of projection.
2 .- Orthogonal Projection: projection when the rays are at right angles (90 °) to the projection plane.
3 .- Projected Outlook: Every projection in one view represents a body in three dimensions, with the way ydisposición as we see in space.
B. Projection plane.
planes are undefined, but may be limited by their traces or lines of intersection with each other. The line of intersection of a vertical plane with a horizontal line called Earth.

- Horizontal Plane: plant also called object or floor plan.
- Plano Vertical: also called standard.
- Plano Side-view or profile, which can be left or right.
land lines or traces of the three planes are the three Cartesian axes X, Y, Z.

METHODS OF CONSTRUCTION OF GEOMETRIC CURVE:
1 .- Method to draw an ellipse given its two axes.
- Plot the major axis AB and CD the minor axis, perpendicular to each other by the middle of both axes.
- Making center in the middle "M", we draw two concentric circles with radii equal to MA and MC.
- then divide the two circles in a pair of equal parts. In this case were 12 equal parts.
- On the big points on the circle, draw lines parallel to the axis CD.
- For the points on the circle small to draw lines parallel to the axis AB.
- Where the lines belonging to the same point in two intersecting circles is a point through which passes the curve of the ellipse.
- Repeat this with all the points of two circles.
- Finally a staff of curves joining the points of the ellipse. 2 .-

- are marked several arbitrary points between O and F '.
- Making center F and F 'on OA opening and arches mark to cut the line perpendicular to AB, which results in points C and D, points of the minor axis of the ellipse.
