3d STL height differences

[jerryhalstead]

I'm creating two versions of (ideally) the same terrain stl, except one of them has a gpx file. Even though they have the same settings, the STLs aren't the same height: the "plain" stl being 47.09391mm while the one with gpx "notch" (using negative gpxPathHeight) ends up taller at 47.45476mm.

What I end up doing with them is bringing into Blender to perform a boolean subtraction that extracts the gpx "trails" (image attached). Then I can combine that with the "notched" terrain file in 3dPrinter slicer to print in separate colors.

I can get it working, with some manual tweaking and post processing of the STLs, just thought I'd report the issue in case it's something that can be fixed or controlled (like passing in a max height in mm?).

Or, even better, an option to output two STLs: the base "notched" terrain and the part that was removed (i.e. the trail). That would be sweet.
