I also make a lot of use of Symbols in area.

This may also help in setting up your own catalogues for using Symbols in area.

And this explains how to use exclusion commands as well for Symbols in area, and Fill with symbols.

Exclusion Commands

Ever needed to fill a polygon with symbols, but exclude the area overlapping with another polygon? CC3+ now includes a couple of exclusion commands that lets you do just this; CONTOURSMX, FORESTX and SYMFILLX. These three commands all behave exactly as their normal counterpart, the only difference is that they will ask you to select entities two times. The first set of entities you select are the ones to be affected by the command, and the second set defines those entities that will be excluded from the command. Below is an example using the Fill with Symbols (FOREST) command. The first image shows three polygons (A forest area with two lakes) before filling anything. The second image shows what happens when using the regular Fill with Symbols on the forest polygon, while the third shows what happens if we use FORESTX instead and define the two lakes as excluded. Except for the fact that you are asked to select entities twice with FORESTX, it behaves the same as the regular Fill with Symbols command. (To change settings for FORESTX, go to Draw -> Fill With Symbols first to load whatever setting you wish to use, but click close instead of Run Now).

I used a symbol for a post (I think from CSUAC) and did symbols along command (some trial and error to get it 'right')

The beach is a smooth as opposed to straight tool - just change the fill to Straight, and it will be fine

Guards' House should be custodum Domus; The plural of Stable is Stabulae. Love the design.
