Hi Tarquin,

Thank you for mentioning TopoDroid, this could be a very good solution in
fact.

*> Perhaps by tapping repeatedly as you "draw" your stroke. *
You are right, in fact when I tested the drawing tablet this is how I drew
some lines. It was a bit like doing pointillism - especially on long walls.
It certainly works, it may just be a little impractical when the cave is
very long perhaps... Maybe it is just a matter of practicing.

Thank you

Francesco

[Therion] Drawing lines with graphic tablet

[Francesco Serafin]

Hi everyone,

I tried to draw the cave's walls in therion's map editor using a graphic
tablet to have a finer control over the lines' shape and obtain a more
realistic-looking cave shape.
This method didn't work because therion's map editor uses Bezier curves to
draw lines: when the pen touches the tablet, a new point is created - but
any further movement of the pen will only adjust the curve's tangent at
that point and doesn't extend the line. To create new points one must lift
the pen and press again so the result is again imprecise.

I was wondering if it would it be possible (and easy) to add a new line
type that is more similar to Illustrator's pencil tool? With the pencil
tool one can hand-draw a path by continuously moving the pen on the tablet
(without lifting it). When the pen is lifted, the software calculates a
Bezier curve from the path.

Thank you

Francesco
