Hi scott, so for removing the visible lines, if you go in "Line style options" and set the "Layer" option for Visible lines to "Custom", like this:



Then the visible lines will all be inside of a "visible lines" group and if you can load the SVG into something that can process it in more detail than MoI's own SVG import then you should probably be able to delete them all in one go like here in Inkscape:
