Expressing Cartesian, Cylindrical, or Spherical Coordinates
You have choices for expressing the coordinates for as Cartesian, Cylindrical, or Spherical. In each case, you also specify whether to enter the coordinates as Absolute or Relative to the working coordinate system. Click the cursor in the first text field to begin entering values or variables. Tab to the next fields, and press Enter when your are done. After you enter values or variables in the text fields, they are evaluated as Cartesian for the Properties window for that coordinate system.
- Cartesian, that is the point’s distance from the origin in the x, y, and z directions in the X, Y, and Z text boxes.
- Cylindrical, that is, the point’s radius, measured from the origin, in the R text box, the angle from the x-axis in the Theta text box, and the distance from the origin in the z direction in the Z text box.
- Spherical, that is, in the point’s radius, measured from the origin, in the Rho text box, the angle from the x-axis in the Theta text box, and the angle from the origin in the z direction in the Phi text box.
