The model to be used seamlessly over the spline should consist of 3 objects, named as Top, Bottom, and Middle. The Middle object is the one that will be constantly tiled along the curve. It has vertices approximately in the range [0..1] along Y-axis. Top and bottom of the Middle object should be open and opposite vertices positions should differ exactly by 1 along Y. Here’s an example of the Middle object:

There may be several objects named “Middle_anything”. They should get identical open edges, but in the middle the geometry may be different. 3DCoat will use random middle objects to place them along the curve. 

The Top object is placed exactly over the Middle object and has an approximate [1..2] range of Y-coordinate. This object is open at the bottom, the vertices should get exactly the same values as on the Middle top vertices. An example of the Top object, marked red:

The Bottom object is placed exactly under the Middle object and has an approximate [-1..0] range of Y-coordinate. This object is open at the top, the vertices should get exactly the same values as on the Middle bottom vertices. Here’s an example of the Bottom object, marked red:

The whole curve will be tiled with Middle sections, the first section is Bottom, the last one is Top. If the curve is closed, only the Middle sections will be used. Open edges will be welded with nearby sections, so if you made everything correctly, the whole object will be closed. So, the final model looks like this:
