LDCad 1.5 Alpha 1 (win+linux)

[Philippe Hurbain]

I made a tread using 57518 part (for 42042 model) using LDCad template. When properly placed over the sprockets and guiding wheels, the tread was 45 links long (the correct value) but there was a gap of maybe 1/2 link wide. I guess that in the real model, play at each link attachment allows to properly close the loop. What I want is to close the gap by making all the links a tad further apart.
