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.

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.

You can't put symbols along just some of the edges of a shape. Symbols along will put them along all edges. I guess you can write a complex macro that figures out which are short and long edges, and calculates positions and puts symbols along them, but that is getting a bit complicated.

To make lines that doesn't change appearance as you zoom in/out, make sure they are using line styles that do not have paper scale enabled:

To align fill in a drawing tool, check out the macros in the Garden tools in the Annual Ferraris city style, it does exactly that.

The master filter is loaded in the OnOpenMacro map note in each individual map. (The SYMICONFLOAD command)
