30, 60, and 90
A plane in autocad is where you begin to draw it is the x and y coordinates if you want to call them coordinates or x and y lines. if your in 3D than it would consist of x y z planes.
x,y and z are rectangular coordinates, start at 0,0,0 move right, this is x direction, turn 90 deg. left, this is y direction, turn vertical this is z direction
That refers to the three coordinates in space.
The x axis comes first! The Y axis is second!Remember: X,Y,Z!
Cartesian, cylindrical, or spherical coordinates locate points when you are creating objects in 3D.Enter X.Y.Z coordinate3D Cartesian coordinates specify a precise location by using three coordinate values: X, Y, and Z.Entering 3D Cartesian coordinate values (X,Y,Z) is similar to entering 2D coordinate values (X,Y). In addition to specifying X and Y values, you also specify a Z value using the following format:X,Y,Z
Usually, cylindrical coordinates refers to the transformation x = r cos(theta), y = r sin(theta), z = z, although x, y, and z can be permuted. Cylindrical coordinates (r, theta, z) are very useful for describing three-dimensional objects whose cross-sections are easy to express in polar coordinates. Circular cylinders are a good example.
(x,y,z)
Points on a grid? It would then be x,y and z coordinates
You can locate a point by associating it to coordinates, either in a two dimension plan, x, y, or three dimensional, x, y, z.
The X and Y axes meet at 0,0. X,Y, Z intersect at 0,0,0.
If x = y and y = z then x = z
