[Therion] Flowstone problems

[Joke Vansweevelt]

I'm working on a topo of a water-cave and I have two questions. 

- How can I stop a flowstone-feature to be filled with water? 
(In the water, defined by "area-water", I sometimes  have features that I would like to stay clear of the water-filling-stripes. If I try to include the borders of this feature as borderlines of my "area-water", usually my whole image gets distorted (not-water areas suddenly  become partly filled with water-filling-stripes etc.). It doesn't work either by defining these features as an area within the area-water (error). 
Objects defined by rock-border don't have to be specified as area border. Rocks are automatically not filled with water-filling-stripes. However, in the case of flowstone features, I would like to be able to define whether they should or should not be filled with water-filling-stripes. In case it isn't possible so far, a solution could maybe be to define flowstone that doesn't need to be filled with water as "line-rock-subtype flowstone"?!?)

- How can I get the borders of "line-flowstone" in my X-Therion drawing to match the borders of my flowstone-feature in the produced pdf-file?
(When some of my area borders are defined as "line-flowstone", in the produced pdf-file, the water tends to invade my flowstone (as far as the borders of the "line-flowstone" that I set within X-Therion). The problem here is that the produced drawing of the flowstone lines is larger than the borders one sets in X-Therion (the scale that I work with for the pdf-file is 1 1000).

Regards,

Joke
