The need for a 0,0 point was removed some versions ago. There's still an entity on each sheet, but it is a special entity you won't see in your map.

Good point @roflo1 . Inserting and then exploding it is perfectly fine. What you don't want is a symbol reference inside a symbol definition, but exploding it takes care of that.

Just to clean up, you can finish up by going into symbol manager (with your symbol editing window open and active) and hit purge to purge the symbol from the definition, since the definition will still remain behind even after exploding

There are trees in regular DD3 style too. Just click the :DD2SKIRMISH: button. CA50 also added additional trees and vegations for this style.

When saving as an image, FT3 uses your currently selected projection. Just switch the projection to Orthographic first, then use save as to create an image.

Seems to be some weirdness with how the drawing tools makes these shapes. Normally, when you draw something, it is made available as the last selection, which is why you can select it with SELBYP and then apply various commands to it. Unfortunately, the rectangle drawing option doesn't seem to be doing this, which means the entity won't be selected, and thus won't have the commands applied to it. Not really a good workaround around that if you can't use the polygon shape, as there isn't a way to figure out what you just drew which is what a macro like this needs to do.
