Hello,

I am trying to compare the cryoEM structures of radial spoke from different organisms. In the mean time, I want to display the same structure from different views. 

I have trouble to adjust the size accurately and proportional within the same and between different models.​

For example, when I adjusted the structure from distal view and then rotated to the proximal view, the distance from screen changed and so the size changed. If I manually adjust the structure after rotation, I don't know how to make the structures from both views identical size.

Similar thing troubles me when I want to adjust the size of two independent structures proportionally.

Hope I made myself clear.

Thank you a lot!
