Defining Cylindrical Coordinates
To define a point using cylindrical coordinates, specify the point's radius, measured from the origin, in the R box, the angle from the x-axis in the Theta box, and the distance from the origin in the z direction in the Z box. When defining a second point, specify its distance from the previously defined point in the in dR, dTheta, and dZ boxes.
- After clicking the desired drawing command, select Cylindrical from the drop-down menu on the status bar.
- Type the point's r-, theta-, and z-coordinates in the R, Theta, and Z boxes.
- 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 boxes.
Tip: Press Tab to move from one coordinate box to
the next. Press Shift+Tab to move
to the previous coordinate box.
Alternatively, click the point in the view window.
