its always in front of d vertical plane..however there are 4 methods of projection 1st angle second angle 3rd angle and fourth angle..but 1st and 3rd are preffered as the views come distinct in second and forth the views are placed one over the other causing trouble in identifying d views
these projections have dimensions
Orthographic projections
because 2nd and 4th angle projection overlap each other
World maps come in a number of projections, each have their own uses and problems. These different projections include a globe, several types of Mercator projections, Robinson, Miller cylindrical, stereographic, orthographic, Sinusoidal, Gnomonic, several types of Azimuthal projections, and others. The US Geological Survey has comprehensive information on map projections available.
Orthographic Projection/Drawing is nothing but representing a 3-Dimensional Object into 2-Dimensional drawing. it is a form of parallel projection where all the projections are orthogonal to the projection plane resulting in every plane of the scene appearing in viewing plane so, Another name for Orthographic Drawing is "Multview Drawing"
the similartes between the drawing is the cow jumped over the moon and went home to his momma :) :) :D :D :P :P
what is orthographic sketching all about?
ISOMETRIC drawings are drawn at 60-30 degree angles. Orthographic projections are views of a 3D object, showing 3 faces of it. The 3 drawings are aligned so that if the page were folded, it would create part of the shape. Also called multiview projections. The 3 faces of an object consist of its plan view, front view and side view There are 2 types of orthographic projection which are 1st angle projection and 3rd angle projection.
orthographic
they help in moving the cell and changing its direction
Because if You can only use 2 planes of view X and Y (2D projection) You wouldnt be able to compare building with its surrounding buildings and area.
They dont have a particular direction,they can face any direction.
