Scaling and locking points in Illustrator

[ETrapp]

Is there any way to lock some points in an Illustrator shape when scaling? 

I have a series of technical wood laser cut puzzles that I need to scale up to a larger size but keep the same distance for the cutouts to slot into. Is there a simple way to do this? 

Thank you!

ETrapp,

As I (mis)understand it, if you are using stroked paths as the basis for the division into puzzle pieces, you can just scale up with Scale Strokes & Effects unticked.

If you have started out by creating stroked paths as the basis for the division into puzzle pieces, and then outlined those paths, I believe the straightforward way is to go back to the original stroked paths and scale up, with Scale Strokes & Effects unticked.

In case Jacob's suggestion does not work with your files, I'd recommend to provide at least one sample Illustrator file, so one may have a look at it.

Also, which version of Illustrator are you using?
