As much as I just 'love workarounds', and a sort of script does appear to exist, has this feature been forgotten?

This was back 2007. :'(

I'd donate a kidney for a line divide tool in MoI3d!

Edit: I just tried the link workaround with a line, and the result was nothing short of terrible.
Does it have to be this hard? SketchUp dealt with line division perfectly. QCad really good too.
MoI3d should be just as good!
