Though there is not much to setup here it can be essential to change some settings when working with large models. These settings are Global which means they are applied to all pages and only to those with only one step. Pages with more steps use settings from the Step Group Setup.
The default value of the Scale is 1,000000 which means 100%. In theory if you print your building instructions, 100% means that your printed model will be the same size as your real model. For models that are larger than your paper, you will need to change the scale to less than one. Again this is a global setting so if you change the scale here the scale of all Assemblies is changed. You can also change the local scale which means you can change the scale of an individual Assembly on a page. This will be explained later.
