That CAD Blocks site has a lot of good stuff. I've added it to the list in the Free Symbols resource thread.

These CAD blocks are actually ready to use symbol catalogs, which is very neat. I first thought I would have to resort to just copy/paste from the drawing, but load them up as a symbol catalog, and they show up as proper symbols.

I'll probably never to cities as competions. The most common thing I hear every time someone announce a challenge or competition is "sorry, I just don't have time right now, working on this other map/real life/etc...". And cities are one of the most time-consuming things out there, which certainly wouldn't help with people having time to take part. (And while you can do something like a Watabou city really quick, that wouldn't be much of a mapping challenge considering most of the work is just changing properties on the import, especially when all the entries are like that)

And for that two-parter idea to work, I would have to put really strict rules into place regarding how to build the city for part 1 for it to be suitable, I don't think that is really going to work out well.

The tools are all set up with a mirror line of 0 degrees as default which results in the ship being mirrored along the X-axis

If you wish to draw a ship withe the nose pointing up, right click :COSHULL:, look for the tool to use, note the name mentally, then hit the Advanced button and select the tool you wanted in the list to the left.

Now, hit the Options button, and set the mirror line angle to 90 degrees. (Obviosuly, this is only possible for tools that have Mirrored Polygon as the draw method)

Hit OK, and then Hit OK again to start drawing. Say no when it asks you to save your changes, otherwise the tool will be permanently modified.

Then just draw your hull.

It's the snap setting. Snap and Cursor snap is on, but for some reason, no grid is selected. This basically causes everything to snap to 0,0 and nowhere else.

Right click the snap button in the lower right, and click on one of the existing snap grids in the list (or create a new one)

The change doesn't change anything in the actual map, just changes some parameters for how CC3+ does the rendering of it.

The setting is persistent in CC3+ until you close and reopen the program, so it will affect any maps you open in that instance of CC3+.

To always have it load for a particular map, you can put DELAYDRAWSYM 0 into the OnOpenMacro of the map file. (Obviously, this will keep it active for the lifetime of the instance and not just for that map)
