Someone gave me a sheet of plexiglass that I need to
cut into smaller pieces. It's approximately 1/16" thick.
What's the best way to cut it without damaging it?
Thanks in advance,

There are several tricks used. I have been successful scoring it with a
knife and snapping it (sometimes) and I have also been successful using an
assortment of power saws, very slowly feed fine tooth blades.
Well, cutting is damaging it...
It can be cut pretty much like glass, you score it and then crack
Some report good success with this method.
I tend to clamp a nice guide to the sheet and score with a stanley knife.
Repeat several times until you'r at least half way through, then slowly
bending will cause it to break off neatly.
As somebody else said, scoring and snapping (as for glass) -- but
perhaps rather than the Stanley knife suggested, perhaps the tool that
is sold for cutting/scoring Lexan would be better: more robust. (I
bought one at HD to use with Lexan, but I've never tried it on Plexiglass.)

My son says the only way to do it is use a RotoZip. It does
seem to work well. You could also use a RotoZip bit in a
MotoTool with a router platform. I thought the high speed
would cause major melting, however, with the right bit it
leaves a clean cutoff.

I've used my table saw, sabre saw, all kinds of miscellaneous power tools. The
trick is to use a sharp blade
with plenty of set (relief) to the teeth. This permits the chips to be removed
without dragging them past the cut edges where friction will melt them back
into the base material.
Most larger cities have specialty stores that sell plastic materials. Its worth
a visit to see what they use back in the shop for fabricating the various
Near the ceiling light panel plastics at the box store is a small
knife with a hook that works quite well. I've used a strip of wood
clamped to the plastic and pull the knife several times and then lay
the mark over an edge like the guide just used and a little leverage
snaps it nicely.

I cut lots of plexiglass on a tablesaw. It is a high polymer and will
stink--use plenty of ventilation. You don't say if you are cutting
curves or not, but a bandsaw will do that too. Any wood-cutting tools
should work okay. Wear eye protection!
I've cut plexiglass with a table saw and a skill saw. But I use a 'plywood'
blade (lots of teeth) and I turn the blade around so it spins backwards.
Never had any problems. It's the same method I use for cutting aluminum
1/16" Plexiglas (it only has one 's') is pretty thin. If it lacks the
protective film or paper covers, lay it on a clean cotton towel and score it
with one of those special plastic scoring knives. They are inexpensive at
the hardware store. With the help of a straight edge (considering your need
straight cuts) score it several times. I find that scoring it lightly the
first few times gets a nice start that doesn't get off the intended line.

As far as the best tool to use, I can't say. I've used plexiglass knives
and they take a long time but look nice if you have the patience. I've
also used a jig saw with a blade meant for cutting plexiglass and the
like. It melted the plexiglass along the edge, but was very fast. Since
then I've heard that a little 10W30 oil on the blade and along the cut
lines of the plexiglass (both sides) cuts down the friction and thereby
reduces the heat. Haven't had the need to try it yet.
Good luck, Carolyn
