I've branched this from Converting Inkscape Drawings of very large caves intoTherion:
I have experienced the stretch using 2 points, and where I have tried this is always solved by adding more points and scraps were needed, but the inside out part I do get more often. I have tried splitting into more scraps, and splitting the lines. The former works totally or reduces the incorrect bit, however a side affect is that the model is not as neat as it should be as the lox model has a 'step' on the scrap join. As demonstrated by the 2 attached set of files. But currently all this is a bit random, and the moving to a new scrap is very tedious, it would be good to have some understanding of the problems, so they could be avoided?
