I've many years history of graphic design, technical writing and technical illustration; my life-long abiding interest in sustainable design led to my returning to school and changing careers to architectural design & architectural illustration; recently I've added Unity development into the mix, to develop a specific set of arch viz tools for VR/AR and realtime explorable environments for my clients.
Architectural visualisations, BIM coaching and consulting, illustrations and more; I've also expanded my original technical writing toolset (which was DTP based) to include topic-based, multi-target type authoring using MadCap Flare, and of course this workflow and data structural concept is easily transferrable to other topic-based authoring tools - Paligo for example.
In terms of BIM authoring tools, though I have moderate Revit exposure (and in fact am to some minor extent supporting its use in my current tech writing role) ArchiCAD is the application with which I'm intimately familiar, and which I consider my main strength; I've also considerable experience with BIMx, some experience with Telka BIMsight, AutoDesk Glue 360, and other such integration tools.
Amongst my 3D Generalist tools, modo is by far my favourite, being powerful, fast, artist-friendly and effective; in many way the procedural modeling system there is a direct match for the kinds of parametric modeling I can do in Grasshopper, but more fluent. I'm very comfortable with modo's various toolsets, from direct modeling through procedural (though still learning a lot there), rigging, animating, materials / shaders, lighting and rendering. Though I know enough Blender to put it in my list, it's not my strength; similarly, though I know just enough Rhino to run Rhino for Grasshopper, I'm no Rhino guru.
