You can also select just a node and delete that also.
Delete the node at the end and that last dimension will disappear.
Delete a node inside of the dimension and the two adjoining dimensions will merge into one.
Also look at all of the options in the pet palette when you click on a dimension.
Where you click will bring up different options.
The places you can click on a dimension are the nodes, the centre of the line between two nodes, anywhere else in the line or the text.
Experiment a little (and read the manual) - you may be surprised at what you are missing.
