You have just created an interesting new round object by using REVSURF to revolve a complex curve around an axis. However you find there are only 6 faces around the perimeter leaving it very rough looking. What variable do you change to correct this?
Set SURFTAB2 to 18
Set TABSURF1 to 18
Set SPLINESEGS to 12
Set TABSURF2 to 18
Set SURFTAB1 to 18

The purpose of the
UCSICON
command is to:?
Permit a user to move the UCS system.
Permit a user to redefine the location of 0,0.
Permit a user to control the placement and appearance of the icon to help you understand your orientation in the XYZ coordinate system.
Provide a working plane to draw on.
Change to the desired working units from decimal to feet and inches.
