FYI: Tips on "Making New House Symbols"

For some time I've been wanting to convert a building design of mine to a house symbol using Sue Daniel's "Making New House Symbols in CC3+" blogs but it has roofs on wings at odd angles (4:3 or 3:4) to the usual compass directions. I discovered that if you

LIST a shaded polygon entity the listing will show the RGB color numbers for "*Angle:" (RED) and "Pitch:" (BLUE) so you can easily add the appropriate colors to your palette for your MAP entities.Now I only have to figure out how to map the central tower (with a crenelated roof) that the house is built around.

If the crenelations are flat, then it should have a blue value of 255, and the direction don't really matter, or if it is sloped, map each crenelation as you would a sloping roof.
If there is a central round roof, the mapping for the roof will look something like this.
You will have to modify the colour palette to get the red and blue right.
PRESETS]. I just had to rebuild 12 custom map colors to my palette for the roofs of the wings. I was going to attach the resulting map file but it is kind of large.
