Hi, In Robert Lang's article about diagramming conventions that can be read at his webpage www.langorigami.com<http://www.langorigami.com> next to Figure 4, it reads "Crease lines should not contact the edges that the creases end upon. They do touch edges that they go under". Does anyone know a justification for this? I find it odd that creases should not be shown in their full extent. The practice dates from the pen-and-ink days and low-res reproduction, where there was not much visual distinction between crease lines and folded edges. Leaving gaps at the end of crease lines makes clearer the distinction between a crease and a folded edge. It’s less necessary now that high-res displays and high-res printing can display clear distinction between (say) a 0.25pt crease line and a 1.0pt edge line. Robert
