How To Use a Copier to Convert Scale Drawings
Like many modelers, every once in a while I work from scale drawings. The drawings are most effective when printed in the exact scale of the model. If done so, they can be used directly for dimensional measurements by laying the model parts on top of the drawings. They can also be used to check the outline accuracy of the parts. Or to cut masks for camouflage designs or markings.
On the contrary, having even the most detailed drawing in a wrong scale is much less useful since it can only serve as a general reference.

The rates are given in percent, which is common scaling notation for photocopiers throughout the world. As they are also rounded off to a full percent, all you need to do is enter a given value on the photocopier and start copying.
Scale Conversion Chart Transposes
Any form of modeling is dependant upon the proper conversion of real "live" dimensions to the scale you are working in.
This particular conversion chart was put together for the International Plastic Modeler's Society and it provides modelers with the ability to scale about any object accurately.
