Hi,

I got this error message when re-starting SU after having Curviloft installed:

"You must install LibFredo6 version 6.9 or higher to run Fredo6_Curviloft"

LibFredo6 is installed correctly. Another Plugin, e.g. Bezier Spline is running without any such error message during starting SU.

Maybe anyone could help me how to fix it?

Regards,

Thanx a lot! That helps!!!

How to move around one end point of a line keeping other end point fixed and without changing length of line?

E.g.: a line from [0,0,0] to [5,5,5]. End point [5,5,5] should be moved/rotated around in 3D-space without changing start point of line (i.e. [0,0,0]) and line's length. In other words point [5,5,5] is moved around on a virtual sphere with center [0,0,0] and radius of 5.
