Große Verbesserung für die Zusammenführung der Teamarbeit:

Messlinien und Zeichenelemente können per Strg+C/Strg+V zwischen zwei geöffneten CaveRenderPro-Instanzen kopiert und eingefügt werden (über den Windows-Zwischenablagenspeicher als XML)

Kommt in Release 25.8.0

I found the cause of the problem. It is in the project settings:

When importing PocketTopo data, CaveRenderPro assigns a device number to each survey leg - either the number
configured for 360° devices or for 400 gon devices. If both of these numbers are set to 0 in your project settings,
the import assigns device number 0 to every leg.

During the cave network calculation, a device number of 0 has a special meaning: it tells CaveRenderPro that the
coordinates of that leg are already known, and it tries to back-calculate length, azimuth and inclination
from the (not yet computed) coordinates. Since those coordinates are all zero at that point, the result is length = 0,
azimuth = 0, inclination = 0 for every leg.

Please let me know if you need any further help!

Hi Thomas,

for my better understanding, could you please give me an example of how you would cut out lines with a polygon? Do you need more than one cut plane?

Regards

Jochen

I will ask my new agent, Claude Code, for some solutions. However, due to vacation, not before April.

This is ChatGPTs suitable answer:

In CaveRenderPro you can keep your surface approach survey for positioning, but exclude it from cave length/depth statistics and from the generated survey skeleton.

There are two clean ways to do it.

Method 1 — Use deactivated survey lines

This keeps the surface line for positioning, but removes it from:
- total cave length
- total depth
- skeleton image
- exports

How to do it
- Open the Data table
- Tab: Data
- Select all surface approach survey shots
(shift-click or filter by station name, passage number, etc.)
- Right-click on the selected rows → Deactivate

Now those shots are:
- shown in blue in the table
- ignored by:
length calculation
depth calculation
skeleton generation
exports
statistics

But they are still available for:
- positioning the cave
- reference coordinates
- visualization if needed

You can reactivate them at any time.


Method 2 — Put surface lines on a separate level

This allows you to switch them on/off via filters.

How to do it
- Assign a dedicated level number to your surface lines
- Example:Level = 9 (Surface survey)
- Go to:Visualization→ Survey Shots → Filter
- Exclude level 9 from the filter

Now surface lines are:
- hidden in graphics
- excluded from skeleton
- excluded from statistics (if filter is active for calculation)

This is useful if you sometimes want to show the approach route.

Splitting of passage and station comes with release 25.1.1

To add splays to the first station you have to add a reference point (1/0-1/0)
