Prototyping part 1: Scaling existing files

- [Instructor] In this second prototyping lesson…we build upon the prior lesson,…where we covered how to start a fresh, new file.…So, what happens if you don't take that great advice…and now your 3D model is totally off?…Well, hang on, I got a way to fix it.…First, let's check how big our file is.…Now this is actually pretty critical,…because, if you remember, we cannot tell how big it is…just by looking at it or counting grid squares.…You can never tell the size…because it could be gigantic or small,…and the squares could be completely arbitrary.…

So let's do a measurement and find out for sure.…I'm going to double click on the perspective menu…to get back to all four view ports.…So you typically want to measure…in one of the side or front views,…that's usually a good way to go.…I recommend using one of the drafting tools,…here it's on the drafting toolbar.…These are the same ones as under the dimension menu,…not sure why they have the different name,…but we're going to go select the vertical dimension here.…
