Hi Jochen,

I am Eric DAVID, programmer of Visual Topo software, I tried the Visual Topo import with Cave Render Pro, and I found some issues :

- There is always an error message at the end of the import, caused by the last lines in the .tro files ([Configuration ...), you should stop importation when you encounter this line.

- The cave is not imported correctly in some cases, especially when the start station is i star (*). A star (*) means "no data entered", so in this case the start station name is the same as the end station name of the previous shot.

I send you a sample file which can help you to improve Visual Topo import.

Best regards.

Eric DAVID

Meanwhile I have implemented following improvements:

1) All survey shots become imported between first appearance of "Param" and "[Configuration"

2) For all survey shots after "Param Topof" the import uses "Start" and "End", else "Length" --> Instrument configuration in CaveRenderPro needs divider 100.

3) Start station with * will filled with the latest station number.

Planned for release 7.5.1
