Duplicate along path with uniform spacing I'm trying to create tank tracks and I've followed the steps outlined in the answer of this question How can I duplicate a mesh along a curve?

As long as the curve is somewhat straight the tracks align quite perfectly, but as soon as there is bend in the tracks, the connector thingy of the tracks do not want to align (red arrow in image) 

I've tried moving the pivot of the individual track but I didn't improve the situation much.. 

How can I make sure that all my tracks align even if there's a curve in the path they follow?
There are generally three possibilities to cause such problem in this particular case:


The resolution of the curve path, which is the least possible factor here;
It seems that you are using Dupliface, it will also be curved by the Curve modifier see Figure 1;
The edge of per panel should better coincide with the joint, in order to minimize the disjoint look. See Figure 2.





I think the most accurate way is to use rigid body constraints, but that would be way too complicated comparing to this way. Hope it helps.
