Here's a "quick and dirty" way to get your fill styles that you create in one FCW map file into a new FCW map file:

1. Start your new FCW map.
2. On the menu, go to Draw -> Insert File
3. In the Insert File... dialog box that pops up, navigate to and select the FCW file with the bitmap fill(s) you want in the new drawing.
4. A cursor with an outline of that map will appear. Click anywhere in the new drawing to place the image of the file. You will see what looks like the original map file on top of the new map file.
5. *Immediately* go to the menu and select Edit -> Undo. That file will disappear BUT all the fill styles you created in the original drawing will now be in the new drawing.

This method is, again, quick and dirty, but easier than trying to create your own templates in CC3. Hope that helps.
