"We are very impressed with the ProtoTech team's unprompted willingness to always ‘go the extra mile’. They did an outstanding job dealing with our application-specific challenges (multiface texture export, the export of polyline entities, model tree hierarchy, etc.), and optimizing large files down to very compact ones, reducing them in some cases by almost 70%. Their strong understanding of current development practices and professional attention to detail make them a dependable development partner.”
