Building an ellipse bank

In the last two lessons, we dug deep into some fairly advanced perspective and determined this ellipse was our master elipse. The elipse we would base all of the other ellipses off of. This elipse is around 18.5%. And let's review how to find the percentage of an elipse. Select the Ellipse path tool or press shift u on the keyboard to cycle through the path shapes. And make sure that path is selected in the top drop down menu. Let's zoom in so we can be really precise. Then holding down the shift key to constrain the shape to a circle draw a circle the size of the master elipse. Press Cmd or Ctrl+T to transform the shape and scale the height until it matches the elipse. You can see in this top height readout that this is around 18.5%. Photoshop can be rather jumpy while working with this and it's hard to get a precise number so settle for something close to that. I should mention for those of you who skipped the last two lessons, that if you have a background in geometry, you'll be…
