At the moment of this writing many of these functions aren't included by default in regular distributions on Blender.org, so i've coded scripts to perform a few of the main features that I missed most. + +My scripts have shortnames: `VTX, V2X, XALL, BIX, CCEN` and are described separately in sections below. `Fillet` and `Offset` are written by zmj100 and can be found [here](http://blenderartists.org/forum/showthread.php?179375). + + +Since I started this repository: Vertex Fillet / Bevel was added to master. So no more need for a separate addon. (Ctrl+Shift+b) + +### VTX + +The VTX script has lived in contrib distributions of Blender since 2010, with relatively minor changes. The feedback from BlenderArtists has been [overwhelmingly positive](http://blenderartists.org/forum/showthread.php?204836-CAD-Addon-Edge-Tools-(blender-2-6x)). I'm not going to claim it's bug free, but finding any showstopping issues has proven difficult. It now performs V, T or X selection automatically. + +Expect full freedom of orientation, but stuff must really intersect within error margins (`1.5E-6` = tolerance). These kinds of functions are handy for drawing construction lines and fixing up geometry. + + - V : extending two edges towards their _calculated_ intersection point. +  + + - T : extending the path of one edge towards another edge. +  + + - X : two edges intersect, their intersection gets a weld vertex. You now have 4 edges and 5 vertices. +  + + +- Select two edges +- hit `Spacebar` and type `vtx` ..select `autoVTX` +- Bam. the rest is taken care of. + + +### X ALL + +Intersect all, it programatically goes through all selected edges and slices them all using any found intersections, then welds them. + + - XALL is fast! +  + - Select as many edges as you want to intersect. + - hit `spacebar` and type `xa` ..select `XALL intersect all edges` + +### V2X (Vertex to Intersection) + +This might be a niche accessory, but sometimes all you want is a vertex positioned on the intersection of two edges.
