Today, the Beta 3 allows to compute the orientation of light sources bound to the part(s) of a light able to rotate or translate.



It also introduces the two following prefixes for simple ball-arm joints:
[font=courier new]sweethome3d_ball_[/font]
[font=courier new]sweethome3d_arm_on_ball_[/font]
these prefixes are used in the light sources of the track lights to give more freedom on lights rotations.

To let you run tests on orientable lights as well as on more doors and windows with movable parts, I finally updated the Kator Legaz and Scopia SH3F libraries, that you can download with these temporary links:
