Thanks for your generous reply.

My tool of choice for the work I've been doing over the last 4 years has been Tinkercad, which is hardly a heavyweight program designed for industrial production mechanical part designers. Rather, it's designed for kids. I teach 3D modeling in K-12 environments, design curriculum for use in those settings, I run professional development sessions for teachers, and I support product designers on an advisory basis. Joinery, modular design and classical "3D sketching" are my primary areas of focus both as a teacher and advisor.

Michael, I'd encourage you to explore augmenting MOI to include a complete set of features necessary to support modular design practices, as I believe there's significant unmet market demand across numerous 3D modeling sectors. The features I believe are most valuable in this regard are outlined in an article I wrote late last year...

MOI is an inspiring product that I'll continue to watch. Is there some way to be kept up to date about new product releases?
