You may read altitudes of points from GoogleEarth. A macro may help. Grey and white PDF you may create from dummy scrap and then crop the final PDF file. M. S. Odesláno z iPhonu 31. 8. 2013 v 21:50, Bruce <bruce@tomo.co.nz>:
Steve I'll be interested to see if anyone has managed to create a ground line as you describe. I assume it is not possible to make it a boundary for the background colour.
I have just tried taking a 3d gps trail with 2m resolution and then including it as a survey line and this can be included to give context in Loch, Aven and pdf outputs. Not sure how well it would work with extended elevations though - I have only tried it with projected elevations. It adds interesting context to plans and elevations, but best with a white background in elevations.
It is quick to produce, but seems a little clunky. If anyone has a better way to include gps trails in therion data I would like to learn of it.
Some snippets below to show what I mean. Bruce
