[Therion] Coloring on a altitude basis

[Marco Menchise]

Hello, I searched in the archives and I didn't find an answer.

I like to make plan and extended sections colored by altitude because this
is a way to add a "3rd dimension" to a plan drawing. I also like to have
the same color in the same cave region either in plan and extended section.
This way makes very easy to identify same portions of a cave in both
projections.

Because Therion colors on scrap basis, I'm forced to draw plan and extended
section using the same scrap subdivision. This is a very complex operation
and it's not always simple to have the same scrap structure in both
projections.

Is there a way or a trick to color by altitude, maybe defining an "altitude
step" to change colors?

Thanks,
Marco

[Therion] Coloring on a altitude basis

[Bruce Mutton]

I don't have a specific solution for you, except to say that I adjusted my 
expectations in this regard early in my Therion career. I also like to match 
plan and elevation colours. I am always conscious when drawing plan and 
elevation scraps of any slight changes in elevation. When there is a change, I 
start a new scrap.  I found it quite easy to adjust to this way of working,  
although it probably helps to have multiple monitors (as with any drawing 
package). There is not a precise match between plan and elevation but I have 
learned to accept it. Short scraps have other advantages if you ever need to 
rearrange map configurations in the future.Bruce
