You're products are so cool and great SW surfacing manipulations. I am reviewing my surfacing again, since I barely use those features for current "cost down" projects at work. I am always impressed with your "tool details" that typically only the injection molding tool designer need to focus onto. I'm curious have you ever had to redesign a feature, because the injection molders were having problems with mold defects, or worse somebody is running a mold simulation software and wants you to make a change for better flow(these guys don't care about the product, just fast cycle time and multiple cavities).

Thank you! Yes I've been designing and building pretty complex forms for lacrosse equipment for the past 12 years. All of my builds have to be built with draft and ready for tooling, so I am used to building for flow, draft, and all of the other details needed for meeting tooling needs while building beautiful surfaces.
