Step 10
After selecting Cube you can create it by dragging in viewport, or by typing values in the fields in the bottom left corner. The values I typed are values I found on Wikipedia. As I said earlier, precision isn’t important. The important part is realistic proportions. Since we can use real values we don’t have to guess though.
To create a box with those dimensions, type the values like in the image (be careful which axis is which. If your axis doesn’t match, change the values accordingly) and press the ‘Apply’ button (if you can’t see the ‘Apply’ button, search for the button with ‘>>’, which will expand your Cube properties). You can see our backdrops are way to big. Since we want the Jeep to keep those dimensions, we will have to re-size the backdrop items.
