it works like a charm here. Attached screenshot and example data (rabbit cave). caveats: - be sure to add "-clip off" option to the area (see screenshot!) - you can even use the wall as second line, so the it clips perfectly there. Am 2020-04-19 13:46, schrieb Roger Schuster:
Hi all,
thank you for your answer. The problem with the direction arrow at section lines is solved. I had missed the explanation in the Therion book because I always just checked the documentation in foot note 27.
Last night I had the idea to solve the problem with hatching using an area. If I draw one invisible border (with -clip off) around the profile and use this as area (type water for example, with -clip off) the pattern also fills the inner part of the profile which I don't like to have. Next I tried to draw a second invisible border just outside of the profile and applied the area to the "gap" between the inner and outer border but this results in really weird patterns. I guess it's because the inner border behaves like a pillar. Of course I played around with different orientations of the borders. It never works as expected.
Best regards,
Roger

Hello, for the hatches: maybe you could do a custom area symbol and use it with "clip off" option. I don't know if this is supported, but it might work. You could try it with some other area first...
And the section arrows are easy by a line option (see thbook p. 29): "direction <begin/end/both/none/point> ▷ can be used only with the section type. It indicates where to put a direction arrow on the section line. None is default."

Hello cavers,
at least in Germany it is/was usual to add hatching to extended elevations and profiles (cross sections) like in the following example:
I guess it will be difficult to do this in Therion because the hatching is outside of the passage and will be clipped but anyway: Is there a way to achieve this?
Is it possible to add an arrow to lines of type section indicating the viewing direction like in this example:
Thank you!
Best regards,
