aaaahhhhh for date you might be right! probably my colour blindness do me some tricks. (maybe using blue to red color scale would be best)
for surveyors, maybe adding a rule so the same color cannot be used for connected or overlapping (plan view) sessions.

not too sure of the spherical selection as it would be impossible to display exactly what you want to display. Polygonal or free-form selection would definitely be perfect or rectangle with the possibility to add several rectangle (i.e. using shift key + mouse graphical selection) but it is probably easier said than done.

tested with a new contours file and it works great!
thanks.

Hi Jochen,
sorry, I'm away from home for a while, will try first opportunity.

Thanks, it does the trick!

Hi Jochen,
Did you had a chance to look further into this?
I think one filter feature should be enough instead of the existing 2: Visualization & Drawings. It would improve the experience to have only one filter feature to deal with. At the moment, the most efficient filter is in my opinion the Visualization one (full colorscale span applied to filtered shots).

Hi Mark,

You can export to drawing layer the followings :
- The survey shoots and stations (but no LRDUs, Volumes or Splays),
- Cave title
- Stations NUMBER, DEPTH, TITLE, INFO, MATERIAL and TASKS (but not the ones assigned to splays)
- Survey shoot colour (as defined in Layout e.g. depth, adjustment, surveyor)

In order to do this
1 - In Layout, select what and how you want to display
2 - In Drawings tab : create a new/blank layer (Drawings). This is to avoid mixing them with your own drawings.
3 - In Drawings tab : in Survey shots, enable "Display", then click on the "Transfer" icon right next to it.

You should get a prompt to confirm you really want to do this... and that should be it...

this is great thanks very much!

Definitly better than it was before but one problem remains. I draw sinter pool with wavy line, and if a wave has a slightly "sharp" angle, then the dashed line behaviour isn't good and give stranger render : the dashed line crosses the plain line. Same behaviour is observered with entrance double-line and show clearly the issue.

Is there something that can be done to prevent this? using a buffer instead of an offset?

Do you mean keeping only the filter feature in Visualisation to set filtering for every tabs (visualisation, drawing, elements, etc) and get the colorscale applied to the filtered data? I think this would be a good idea.

Hi Jochen,
this is primarily when Drawing/Elements that I need the altitude colorscale to be applied to the filtered data. With many splays, ti is a lot of data often overlaying and it would be very useful to have the colors scale always applied to the filtered/displayed data and not the whole set of data... that would be great!
Surveying in Laos at the moment :)

Never used Sexytopo. However looking into the import format available into CRP, I see Sexytopo (*.txt). If this doesn't work maybe there is a bug that Jochen could fix.
Otherwise, CRP can import Therion *.th files. And I'm sure Sexytopo exports survey to *.th format (you might find *th2 file but these are not survey data files).
