This set of files comes in the following formats...WPC (Pazzles, Funtime Software) AI (for KNK) and  *GSD (Silhouette, Craft Robo, Wishblade)
There are 6 separate files that include both the outline of the castle and an inside piece already fit to attach to your acrylic.

*GSD files are smaller due to the size of the page output.  If you have a larger format cutter, simply take the complete castle and resize it all together to keep it matched.
