This works best for smaller cuts. You can do this for larger cuts, but make sure that the score is deep enough. Plexi likes to "run off course" if the score line is not sufficiently deep. You may want to score both side of the sheet to help prevent this, but unless you are extremely careful, this tends to make for less-than-flat edges. Also, what sometimes helps is to score the edges of the sheet with the file on the ends of the score line, this helps to "start" the break when you strike it. Also, I've found that what works well to hold plastic is hot glue (ala hot glue "gun"). It holds really well, but if for some reason you need to seperate parts, you can usually cool down the area (freezer or ice cubes work well) and pry them apart. Doesn't look real nice, tho, so you may want to keep the hot glue joints out of sight. -- Disclaimer: All spelling and/or grammer in this document are guaranteed to be correct; any exseptions is the is wurk uv intter-net deemuns.
