PHEV - Pluggable Hybrid Electric Vehicle
Made as part of G.hn technology presentation. While not really a stencil per se, I thought it illustrated use of bezier curves and having semitransparent objects overlaid on others. Feel free to add/modify and update this thing. EVSE = Electric Vehicle Supply Equipment

Markov chains
Simple self-looping arcs and two-way arcs with custom circles, to allow links and self-links with the correct angles and spacing. (16 radially spaced magnets per circle - two magnets at each of the four cardinal directions, and two at each of the multiples of pi/4 45 degrees).

Regular polygons
Regular polygons, all set and ready to go, from 3 to 15 sides.
Chemical Engineering 3
A basic stencil for chemical engineering diagrams (Stencil 3).
Conversational Architecture
A stencil for the Conversational Architecture design language, used to specify multi-channel, multi-modal and multi-directional web and mobile applications.
ArchiMate 2.0: Behaviour
Stencil for the ArchiMate modelling language from The Open Group. This is one of the four stencils comprising the core models for ArchiMate 2.0. This stencil specifically contains the behavioural concepts. For more information on ArchiMate, see the website of The Open Group.
