Not sure what you mean by vertex info. Do you mean the transformation matrix
applied to each part or the details of the parts themselves? If the latter you
can't get at them but the former is all stored in the zipped XML file in the LXF
file (just unzip it with any program). They're stored as a vector normal and
angle IIRC so you'll need
http://en.wikipedia.org/wiki/Rotation_matrix#Exponential_map that.
