Hi :)

If you open the catalogue file (that's the [Foldername].FSC file usually visible in the parent folder of the [Foldername] containing the symbols), you can export an FCW file with all the symbols arranged neatly and ready for printing using the "Create catalog thumbnail file..." option.

In this example I created a Test.FCW file on my desktop which looked like this when opened.

The blank space at the top left is a drawtool and not a symbol, so it's name is there but the sample line is not.

I then exported a jpg bitmap from this and got this result (this is only a 500 px export to preserve the copyright on these symbols on the forum, but you can set it any size you prefer using the Options button in the Save as dialog.

This works for each catalogue at a time, but it doesn't take too long to do, and if you print each one you can make a reference book of them for yourself.

Similarly, if you want 2.5 foot wide walls you will need to edit the 5ft snap grid (right click the Snap button to do this) and make 4 snap points instead of 2, then draw your room 1.75 ft larger than you want it on the first snap point outside the boundary of the floor space.

Or for 2 ft wide walls you need to use the 5 snap 5 ft grid.

That has little to no effect.

What usually causes the problem is if you have loads of House entities rather than symbols, because they are built from filled polygons and dramatically increase the node count.

You can work on a district at a time and then move a completed district to a layer of it's own and hide it until you need it later to check on how things look overall, or for rendering.

Use List in the Info menu to find out how many nodes you have in that large landmass. It's the node count that really slows CC3 down. over 10,000 is where it starts to get slow, while 30,000 is nearly impossible to work with. But do you really need that many? In most cases, not really.

If you can get away with it without losing something important, use SIMPLIFY to get rid of unnecessary nodes. Even if you use a very small factor with SIMPLIFY, it will still get rid of any nodes that are right on top of each other and not really doing much because they are too close to make any difference.

Fractalise is a high risk tool to use. If you use it too many times all you end up doing is making the coastline frilly and CC3 slow, neither of which are good things. I don't recommend fractalising anything large more than twice with the default settings and definitely no more than 3 times. You also have to consider that however many nodes you end up with in the coastline you will double that if you then trace the coastline with all your terrain fills.

If you want to be able to edit and trace your coastline, use a colour key for the central ocean instead of multipolying the two parts. A multipoly can't be traced, edited, or fractalised.

This is a bit different to entire toolbars vanishing, so it might be worth re-contacting Tech Support before you reinstall if it comes to that.
