If you use the symbol catalog template, it starts with basically nothing to be able to create clean catalogs.

I've always found it best to just think about what you have good ideas for. A map always ends up best if it starts with a good idea, rather than just start with a random area. So just go through the map in your head, think a little about what you would put there if making a map. Then decide if you have a good enough idea for the larger area or not.

You can create a new map the normal way, and then just use clipboard copy to copy over the entities you want, and then trimming away the parts you don't need with tools like :CC2BREAK:/:CC2SPLIT:.

Lots of information here:

Ralf also did a live stream:

Yea. The tools are only a quick way top draw polygons using the fill, but they are just the same as regular polygons and affected by changes in the fill setting the same way.

Note that by turning OFF scaling, it means CC3+ won't keep a consistent scale between zoom levels, and screen and export. With scaling off, what looks nice on screen may not look as nice on export.

Resolution of 5000x5000 with an antialias of 75 is not going to work for most people. That high of an antialiasing setting is generating a work image of over 11000x11000. Pushing it that high can work if the stars are aligned just right, but is not recommended.

For the sake of testing the script, try something more reasonable, such as a resolution of 2500x2500 and antialias of 20%. You can try to increase it when you know things work at that level.

When I test the scripts, I usually just set the res to 1000x1000 without antialias. The final result won't be great, but it runs through things that much faster.
