I would like to ask two question about paths Sorry for my poor English first, and hard to describe my question just in few words in title. thus I display a schematic diagram below. The first one is how to move a node on a line along another parallel path Actually I know how to generate series of parallel lines with mutiple nodes, and I know that pressing ctrl while moving the nodes can let that node move horizontally or vertically. But I want to do is as the diagram, that is, the node move along the path and make the interval unchanged.
The second question is that, is it possible to make two intersected segment into one path just like the diagram? I could only zoom my file to very large scale and move nodes by mouse, it is hard to find un-parallel with normal scale but this is still a stupid way anyway.
