Plugin request - part line geometry

[gaganraj]

Would it be possible to create a 'part line maker?'

basically, when doing a lot of props and vehicles I add part lines in photoshop post. It would be cool to draw your part lines in with the 'tools on surface' plugin, then hit a button and have the part line geometry created. It could be 'V' shaped or 'U' shaped etc.

thanks!
