Select the part you want it to pivot around then select the rest.
It will always pivot around the pivot point of the first item selected.

You can make it visible and draggable with the mouse.

| (...) But, rotations are limited to parallel to the X,Y and Z planes, so I don't think you are addressing what I'm talking about. Imagin you had an axle that is at 45 degrees in the XY plane, and you have a biped leg you want to rotate around the (...) (19 years ago, 7-Jun-05, to lugnet.cad.mlcad)

| (...) Hi Eduardo, All the models I enter are technic. Compared to brick building, technic is much harder. With the standard bricks, everthing is turned multiples of 90 degrees, and studs line up parallel to the x,y, or z axis. Jaco is right, it (...) (19 years ago, 6-Jun-05, to lugnet.cad)
