Under the so-called category “notable lines” plane are those that are parallel to the planes of projection diedricos. These lines are very useful in the operation that we will develop in this system of representation.
One of the most important theorems of descriptive geometry is the so-called “Theorem of the three perpendicular”, It establishes a relation between two lines perpendicular when one of them is parallel to a plane of projection.
Can you get from a projection of a belonging to a flat point another projection on the plane dihedral to the full? For example, If give us the horizontal projection and vertical of a plane and a point in the latter as determinaríamos the projection on the horizontal plane?
Do you want to add a 3D object can be manipulated in your blog? Would you like to share your models with the community? Youtube-as it allows us to watch videos and incorporate them into our spaces of communication, There are tools to share 3D content.
We have seen some repository of 3D models dedicated to the world of space exploration as the “Celestia Motherlode” NASA, You can download these models in some relevant formats.
Sketchfab is a platform to host and share our 3D models, which allows to visualize them embedded in our blog.
A plane is determined by three unaligned points, so adding a new point to a straight line projections can define it. In this case we will give at least two related dimensions on each plane of projection in order to become independent projections of these plans support of representation. We will learn to represent maps and items belonging to them.
