<div dir="ltr">I am not seeing this Bruce. I just tested with 5.3.16. My survey imports the centreline from a Survex .3d file however, so that might make a difference? Or maybe I am not understanding what you mean by including the centreline in the map. I turned off the centreline using 'symbol-hide line survey'. If I comment that out in my layout then the centreline is drawn in the map, but my altitude range still covers only the range of my scraps.<div><br></div><div>Footleg</div></div><div class="gmail_extra"><br><div class="gmail_quote">On 5 January 2015 at 22:40, Bruce <span dir="ltr"><<a href="mailto:bruce@tomo.co.nz" target="_blank">bruce@tomo.co.nz</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
