Thank you for the help. I had done what you suggested. Ive also pasted this with Jaco van der Molen from lpub and we have just solved it. For some reason after I had done an edge only pic of my truck model for my son to colour in then reverted back to the original settings, lpub decided that that was too good of an idea and not except the "reverted" settings no matter what I tried. The only thing that stopped it was reinstalling LDview, which I upgraded to the 4.2 64 bit beta version. Upon opening lpub it wanted (finally) the ldview path dir. and would no longer crash when you open the preference window. Now opening the models that were made as a line drawing it was just a matter of pressing the redraw button and this fixed those models. So all is well now. Thank you for you time Travis.
