[chimerax-users] Measuring Tilt of Helices

Dear ChimeraX users,

I’m trying to measure the tilt of the helices with respect to the helical axis (i.e. the z-axis). As depicted in the image below, I was wondering if it would be possible to draw a line parallel to the z-axis, traversing through the stack of helices, and another perpendicular to the z-axis and finally measure the angle between the axis passing through the helix (generated by define axis command) and the perpendicular drawn to the z-axis.

Thanks in advance Abhi
