I spent several months helping James Gavey Architecture in Castel, Guernsey to level up their ArchiCAD use and create a new template file for their evolving workflow, and during that time also helped with both BIM modeling techniques and some special modeling tasks accomplished in a mix of tools, to get needed higher-complexity items for use in client-facing renders, and in some cases investor-facing renders. These included some high detail (for BIM) guitar models, some motorcycle models, and a number of context buildings and sites.
On the BIM coaching and development side, I helped JGA go from an almost exclusively 2D set of workflows of ArchiCAD, with no layer management to a modeling-centric, BIM automated tool focussed set of workflows, designed to position JGA for future growth, more complex project types, and better overall consistency of both design and output. We explored (and I coached) basic BIM modeling, more advanced techniques, and use of hotlinked modules; we added profile-based workflows for parapet wall conditions frequently found here in Guernsey, and I delivered two pre-final templates showing JGA layer combinations, graphic overrides and a wide range of more effective tools.
I also developed a series of bespoke materials using Substance tools for their use in renders and in ArchiCAD documentation, whilst encouraging JGA to explore a wider range of rendering tools, as they had hit a severe bottleneck in their current rendering workflow - in specific I proposed their exploring realtime rendering options - hence my supplying these materials in a PBR centric method. I had started developing a series of textures for material development for JGA based on scanned materials from JGA projects - using Substance Bitmap to Material to develop high quality delighted maps, with displacement, normal, specular and diffuse for use in a range of tools - this effort has been for the moment put on hold.
