I've not used the loft tool much but in my experience problems in the Vertex Modeler are often caused because a vertex is not exactly where you think it is. So for lofting it probably helps to make sure all vertices for a single cross-section are on the same plane. Using one of the 'plane' views (Front, Top etc.) is a safer bet for moving/adding vertices than the Director's View. Having said that, I'm not sure that the Spline Modeller isn't a quicker and more versitile way of doing anything involving cross-sections. And if you need to use the VM, link the vertices by hand and then fill the polys. HTH Mark
