Adding and deleting lines with the Mesh tool

In this movie, I'll show you how to manually assign rows and columns to a…gradient mesh so that you have as much…control over the process as much as possible.…As I was saying in the previous movie, I…want to specifically add more column lines around the outer edges…of the shape, as this volumetric object is declining away…from us, and you do that using the Mesh tool.…So go ahead and select the Mesh tool, either by clicking on its icon or pressing…the U key.…Next, to add a new column line, you want…to click on an existing row line because you…always end up adding a line perpendicular to the…one that you click on, so I'll go ahead and…click right there in order to add this kind…of contour, and then I'll go ahead and click over…here in order to add a column line to…that location, and I want to add another one right here.…

Now, if you need more row lines, then you click on an existing column line.…For example, I'm going to create a new row line…right about there and one up here, as well.…Now, at some point you may want to move an existing line around.…
