My experience matches what Martin describes.

Since about version 5.2.8+- -outline in/out does not seem to have affected pdf outputs much if at all.  However it is still of critical importance for .lox and .kml

Your example would make a nice addition to the therion projects page http://therion.speleo.sk/wiki/doku.php?id=projeurope

>Lots of the 'smearing' is from made up surveys, constructed from old plans.

I have had this effect where drawings extend beyond the influence of survey stations (both 'real' and 'made-up' surveys).  Any tips as to how to prevent or minimise this?

The Longwood cave (in the Charterhouse set above, screenshot below) seems to have a matching survey centreline and model when viewed in plan, but the model is still smeared and the elevations of the smeared 3d model do not match the survey centreline.  I assume this is because the drawing is not ‘connected’ to the centreline by way of point ‘survey-station’s, and if it were, presumably this view would become the more realistic 3d tube we are accustomed to.
