You can use TOFFSET in a macro, but it is a bit tricky since it uses single entity pick instead of a regular selection. Means you cannot select with prior, but you can select it if you know the coordinates of the entity (But these are tricky to get for an entity drawn with a drawtool)

Depending on the kind of offset and lines you need, the double lines [DBLN] command may be easier to use in a macro.

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.

It doesn't matter at all. Units in CC3+ are meant to represent real world sizes, so you make the map in 240 x 180 if it is 240 by 180 miles (or feet/meters/kilometers depending on map type) or 2400 x 1800 if it is 2400x1800 miles.

For an overland map, symbol scale will vary, as you pointed out yourself, and many drawing tools have line width expressed as fraction of map size, meaning they will vary too.

For dungeon/city maps, the larger map will give you a larger area to work with, since symbol scale don't vary with map size.

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.

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

Here's Joachim's tutorial: https://forum.profantasy.com/discussion/comment/8891/#Comment_8891

In :CC2PRESETS:, make sure to pick the correct draw tools (These are the names of the folder the tools reside in). Obviously, you should do this in the template to ensure new maps crated from it will work properly

The file Ralf referred to above is still located in the same location for CC3+, just look in the CC3+ data directory and follow the path. This is a Cosmographer supplied filed though, so you need to have Cos3 installed, there isn't one available for "plain" CC3+.

It is a template file, so it won't show in the CC3+ open dialog unless you change the file type filter to show templates instead of maps. You would normally using the new map wizard (choose a pre-defined template) to create a map from it though, not opening it directly

Nice use of the color key effect there. Very elegant solution to the problem.
