Dedicated CAD software speeds up drafting significantly with functions like: Extend, Trim, Intersect, Fillet /w radius and Offset /w distance. 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.

Since I started this repository: Vertex Fillet / Bevel was added to master. So no more need for a separate addon. (Ctrl+Shift+b)
