Hi ushumgal Hi everybody, @ushumgal said: Thanks for the links to the plugins, Simon...TIG's extrude edges by rails is amazing!! I'm having some success with it, but I do have a question. I divided the arrowhead into 3 segments (which all have somewhat different sections). When using this tool, how do you merge one segment into the next? Tig has is own explanation about that: Here But In fact it was very uneasy to skin the middle segment with EEBR for it was not possible to skin directly 4 joining curves. I said "IT WAS" because ExtrudeEdgesByRail V2 is out and this limitation has now expired Segmented arrow: [image: Arrow2nd_001_th.jpg] [image: Arrow2nd_002_th.jpg] [image: Arrow2nd_003_th.jpg] You can also use Soap Skin & Bubble Which add the possibility to inflate or depress the skined faces. The process need to be initiate with Weld operation for SS&B works with two joining curves. Some small fails may happen and need to be repaired. Something a bit difficult for newbies. [image: Arrow2nd_004_th.jpg] The two different skins: [image: Arrow2nd_005_th.jpg] .../ I see you are doing skins manually to join your curves (good thing). This can be made with plugins. Unfortunately, powerful ArchitectBoy's Skin.rb (& see also& skin thread) only skin separate curves, but Rick Wilson Curve Stitcher does it very simply (you can throw a glance on my little skin reminder here even if it must be updated) ++simon
