Hi all,

In the process of creating piece 6643 (technic flex system connector), I've
noticed the lack of several official primitive that I need. Included in this
message is the first. Please notice that I am stil somewhat green in Ldraw
(but I have significant CAD experience). I think everything is correct, but
I encourage you to leave any feedback.

Next, I'm going to be working on is 2-4cyli2.dat.

Thanks

This look OK, but is not consistent with the other 2-4ring* primitives. Yours
comprises the two quadrants in the -z direction - for consistency I believe it
should comprise the two quadrants in the +z direction.

This already exists in the unoffcial parts download, as I needed to make it for
the Classic Space bendy arm holder bricks

I'm not sure why you would need a 2-4cyli2.dat - how would this differ from a
scaled up 2-4cyli.dat ?
