 You should now see the right hand segment on your standing model. The right hand segment coordinate system and graphic are not oriented correctly. If you do not see the hand segment after clicking Build Model, double check the values you entered in the last step. We need to rotate the coordinate system to the correct orientation. You should now see the right hand segment on your standing model.
