The only difference between regular image exporting and rectangular section is that after you have clicked save in the save as dialog, instead of starting the export immediately, you will be prompted (on the CC3+ command line) to pick two opposite corners of your export (by clicking your mouse in the drawing or typing in the coordinates, either works). CC3+ will then export only the parts that is within the area defined by those points instead of the entire map.

The export process is explained in detail with images in the user manual, starting on page 47.

If you are printing, there is a tiling option right in the print dialog, just set the desired scale (battle maps for miniatures are usually 1' = 5" (as long as your map is mapped to scale in the first place)) and set the horizontal and vertical number of tiles. Check page 47 of the user manual for details.

If you are exporting it to image files first, you can use the "Rectangular section" file type exports. This will cause CC3+ to ask you for coordinates after hitting save, and this way you can save just a piece of your map. Just use this to export your map one piece at a time.

Ouch. Sounds bad, been a little while since your last post. Good to hear you're feeling better though. Hopefully you're back to full health soon.

Much better, but the shadows from the furniture still seems a bit on the longish side....

No. The viewer product was discontinued. The problems with a viewer for CC3/CC3+ is that maps rely on artwork installed on the users computer, the .fcw files themselves doesn't have this embedded. This means a viewer would require the exact same installation of artwork as the actual product, which has rendered the concept of a viewer a bit difficult. The original viewer concept was from back in the CC2 days where all artwork were vector artwork that could be embedded into the map files themselves.

To view .fcw files you will need to have CC3+ installed, as well as the same add-ons that were used to create the maps so that you have the same art resources avilable.

If you're interested in trying out CC3+, there is a 14-day money back guarantee, but otherwise I recommend you ask the person sending you the files to export them as an image or print them to a pdf file instead.
