Hi Michael,

> Yeah I think that will be possible. Probably by default the hidden lines on PDF export will not be displayed but I'll put in an option for having them and when they are enabled it would make sense to give them a faint dashed line style in the PDF file as well I think.

Will you keep this option on final release, or you drop it? In some cases this can be quite usefull. If it means no extra work i suggest you keep.

Another question, will you consider making a 3D PDF export, or it is a monster task? Maybe for v4 : ))
