Dimension Lines

READ ME

OK Based on TinyWeenie's code for dimensioning in inches script for adobe illustrator, I tweaked it a bit and did the following CHANGES:

1. Set default swatch to black so that you guys don't need to create a "cutter" swatch.

2. Restricted the numbers after the decimal to only three instead of infinite since illustrator's precision only goes three numbers after the decimal.

3. Tidied up the code to make file smaller, feel free to delete all comments /**/ and use JavaScript Minifier to paste the code below to further make the file size even smaller.

BELOW IS THE SOURCE CODE:

/*

Dimensioning - Nick Blakey 2007

This will add measurement marks and dimensions to any selected item.

This script requires that a swatch already exist for the colour "Cutter" (or "cutter")
