Quick Measurements on Untraced X-Rays
Users can make quick linear and angular measurements on any x-ray in Quick Ceph, even if it has not been traced. If an x-ray is calibrated, linear measurements can be made accurately. To make a linear measurement, hold down the “option” key on the keyboard, then click and drag the mouse on the screen.
You can make an angular measurement after making a linear measurement by clicking and holding the mouse button elsewhere on the screen. The first line will become the first vertex of the angle and the cursor defines the second vertex.
