Dear John,

Is your problem in visualization of the xvi or in the produced pdf?

When you warp background images into a xvi in an elevation, there is indeed a bug: the warped sections are correctly warped but they are incorrectly placed with respect to the centerline/splay shots. If you look carefully outside the drawing area (usually in the upper-left corner after a proper extension of the visualization area). See the example in the joint email I sent one year ago.
A workaround is to double click on the sketch with the right button to translate the sketch were it should be with respect to the xvi, but one has to do that every time one opens the file in xtherion.

I have produced a section on a bearing using

export map -proj [elevation 075 deg] abc.xvi

Using this I have created sections across a cave showing passages at different levels along a sectional line.

These sections are scraps

es1

es2

es3

and create a map

map es

es1

es2

es3

endmap

export map -proj [elevation 075 deg] abc.pdf

export map -proj elevation abcd.pdf

But when this map is selected and a pdf is created, all is produces is a pdf version of the xvi file (abc.pdf,)(but not drawn sections just the centrelines/splays)

or an extended section but not on the bearing abcd.pdf. (ie the sections are produced but not in the correct places)

I have tried changing the scrap projection settings to no avail.

Any ideas
