Colour by Altitude Is it possible to colour by altitude along the wall edges only ? I do not want the scrap filled with colour, just a colour edging along the walls, either inside or outside and preferably able to define the colour width. Perhaps add a feature to the colour fill function to allow the user to specify complete fill or edge width plus inside/outside ? Cross Sections I have a major cave system in Survex with lots of splays that help define cross sections and I am in the process of converting it all to Therion again - was not happy with the first conversion due to my inexperience with Therion. Is it possible to create a cross section within Xtherion by selecting the station and only the splays that define the cross section ? That is, either the software automatically grabs the splays within a certain threshold perpendicular to the centreline or the software allows manual selection of which splays to use. My current method of manually creating cross section data subsets is time consuming. Thanks, Kevin

Perhaps add a feature to the colour fill function to allow the user to specify complete fill or edge width plus inside/outside ? Have a look at the metapost for the built in line definitions. It might be possible (once you have deciphered how metapost works) for you to replace the standard wall definition with a custom one of your own. There are examples that show how to create an offset line in the existing code, (line wall subtype pit, and subtype over or underlying) so this could be modified to create a narrow boundary to fill with the map-fg colour (altitude in this case). See http://therion.speleo.sk/wiki/doku.php/metapost to get started. Bruce

The code of topParser is there for selecting the sprays within x degrees of a cross section, but I have not finished the implementation or tested it, unfortunately limited time to progress this at the moment, also only works for top files Andrew
Thanks,
