style='font-style:italic'>No. Nothing wrong with join, although join does add
an extra layer of complexity when you are trying to debug problems, because the
morphing disguises other things that may be going on. It is more likely a
poor choice of projection view angle. From your earlier post (below) it
sounds like you have extended profiles, so if your projected elevation angle
looks ‘end on’ to the passage you will get a real mess.<o:p></o:p></span></i></span></font></p>

style='font-size:10.0pt;font-family:"Courier New"'>>The profiles for the
real cave I am working on were sketched along the survey line. That means
they bend and twist as the survey line bends. In this case the survey
line is very close to running down the center of the cave, but that is not always
the case. One leg from the T-Junction has a "dog leg" bend in
it. At one station it goes from north to almost east for about 70 feet,
then it turns back to almost straight north. The profile sketches follow
the centerline and so make the same twist.<o:p></o:p></span></font></p>

exactly, however if the passage is traveling towards or away from (or close to)
the projection angle, the morphing will be very messy – hence the

your elevations are –projection extended, then all selected extended maps
will be exported each time. I should test it now, but am too lazy,
however my experience from several versions back is that Martins suggestion of
sequential selections and exports does not result in the segregation of map
outputs you are looking for. Either Martin is right, or will need to
modify th-config between runs (or use indexes – not a good idea in this
circumstance – constrains your options later on for rearranging maps). <o:p></o:p></span></font></i></p>

though of using offset in your extended elevations as an alternative to

<p class=MsoPlainText><i><font size=2 face="Courier New"><span
style='font-size:10.0pt;font-style:italic'>You can use offset to separate passages
that would otherwise overlie each other. This would give you segregated
