Try

No, points symbols are scaled, although not linear. In the 1:600 scale they
are exactly half the size of symbols in 1:200 scale.

 Is there anyway to scale the  point symbols,

If you'd like to have more control, you may use

1) base-scale command in layout (see thbook)
2) directly change the size of symbols using following code in layout
(undocumented and not recommended)

code metapost
  u:=5pt; %%% or any other value

Both commands change the apperance of line symbols as well. Map symbols were
not yet optimized for different scales (we mostly use 1:200 and 1:2000 /
1:5000 without symbols). Suggestions are welcome.

u: = 5pt really helps! It doesnt seem to effect the line water-flow arrow 
heads.  As there anyway to scale them down with a simple metapost line?

Thank you for all your hard work! :)

[Therion] Point scaling.

I am drawing a large map and had to in increase the scale from 1:200 to 1:600.  
Therion seems to scale walls and lines really well but the point symbols stay 
the same size for any scale.  Is there anyway to scale the  point symbols, 
other then typing -scale tiny |small | normal | large | huge for each point 
symbol?
