Use this command to place repellors (you may still place repellors using the flags for genr8). When you have placed the repellor, you may move it around just like an ordinary Maya-cylinder. If you use this command it is a good idea to remove the repellors with degenr8, since it cleans up the MEL-variables that are generated. If that is not done, things may behave strangely later. If you select a repellor when this command is executed, you will be able to edit the values of the repellor.
The repellors that are being drawn are ordinary polyCylinders and as long as you do not change the name of the repellor, feel free to alter the position and the size.
If you select a repellor and use the repellor command, you will be able to edit the parameters. Whenever you change a value, you should hit enter while the cursor remains is in that field. If you edit a repellor, you will get the GUI, regardless of the presence of the -g flag.
