I need to edit the vertices of about 30 polygons in an equal way, how would I go about this? Alternatively is there some method to just increase the size of a group of polygons 200%?

Good question. I hadn't heard of scaling before - it should be part of the buffer tool in my opinion. – Ian May 1 '12 at 0:20

I believe this is possible using the scale tool:

It might not be enabled by default, so you can turn it on.

Here's a tutorial of how it works:

Failing this you could always do a buffer and then union the output with the original file, although this a bit of a 'dirty fix'

I can't find scale in 10? – sni Apr 30 '12 at 23:52
I think one way I can get around it - not preffered though - is as I am using data driven pages I can change the extent of my grids..I think – sni May 1 '12 at 0:13
10: To use the Scale tool, you must first add it to an ArcMap toolbar from the Commands tab of the Customize dialog box. The Scale tool is found in the Editor category. Click the Edit tool on the Editor toolbar. Click the feature that you want to scale. Click the Scale tool on the toolbar to which you added it. Move the selection anchor (the x), if necessary, since the feature is scaled based on the selection anchor's location. Drag the pointer over the feature to scale it, or press the F key to set a scale factor. Release the mouse button when you are finished scaling the feature. – Ian May 1 '12 at 0:19
I can't seem to add it? nothing happens when I click the scale button and check my editor box – sni May 1 '12 at 1:21
