Defining Cylindrical Coordinates

To define a point using cylindrical coordinates, specify 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. When defining a second point, specify its distance from the previously selected point in the in dR, dTheta, and dZ text boxes.

1. After clicking the desired drawing command, select Cylindrical from the pull-down menu in the Status Bar.
2. Type the point's r, theta, and z coordinates in the R, Theta, and Z boxes.
   Tip:

   Press Tab to move from one coordinate text box to the next. Press Ctrl+Tab to move to the previous coordinate text box.

   • Alternatively, click the point in the Modeler window.
3. When drawing objects other than polylines and helices, the second point you select is relative to the first point. Type the second point's distance from the previously selected point in the dR, dTheta, and dZ text boxes.
