When you create objects in 3D, Cartesian, cylindrical or spherical coordinates are used to locate points.
Enter X.Y.Z coordinates
3D Cartesian coordinates determine 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
Enter Spherical Coordinates
3D spherical coordinates specify a location by a distance from the origin of the current UCS, an angle from the X axis in the XY plane and an angle from the XY plane.
You specify a point using absolute spherical coordinates with the following syntax:
X\<[angle from X axis]\<[angle from XY plane]
Enter the @ sign followed by the relative spherical coordinate values, if you need to define a point based on a previous point.
Enter Cylindrical Coordinates
3D cylindrical coordinates describe a precise location by a distance from the UCS origin on the XY plane, an angle from the X axis in the XY plane, and a Z value.
You specify a point using absolute cylindrical coordinates with the following syntax:
X\<[angle from X axis],Z
When you need to define a point based on a previous point , you can enter relative cylindrical coordinate values with the @ prefix. For example, @5\<30,3 specifies a point 5 units on the XY plane from the last point entered, at an angle of 30 degrees from the positive X direction, and extending 3units in the positive Z direction.
