Quote:More clarification point: in a technic axle (but also in a bar and other \"clippable\" parts) connections are at discrete positions. There is not an axle connection at some position and long x Lego Units, but a serie of single connections each one oriented ad positioned at 1 LU from previous and next all along the part (for example the axle). Instead for sliding connections (IE in pistons, pneumatic and other parts) there is a starting and ending point of a continuos line of available connections oriented along the line.
Ah - does this mean that a technic axle cannot slide inside a technic brick with a hole? I would think the axle is a "fixed" connection (like the clips) for some holes (like the + shaped hole) but slide/translate for a round-shaped hole.
