Hi everyone,

I am currently using MoI to design a model of a ship which I intend to create in physical form using paper card. Things are going quite well. I've managed to work out how to unfold my MoI model to flat shapes via Google Sketchup using a free Ruby script and also how to create a pdf file with correctly scaled parts by using a freeware pdf driver.

The ship's hull in the attached image was 171m long in reality but is 219m long in MoI. I need some help to resize my MoI model to match its real world dimensions, or better, to make MoI recognise that my ship is 171m long by resetting its internal scale to match my model. The reason this is a problem is that I have several plan images which do not rescale with the rescale of my model. The images took me ages to arrange and I don't want to upset their relationship to my partially completed model.

Any ideas would be much appreciated.
