I'll tell you this. Trimble is not getting the money for Pro out of me until it's 64 bit and multithreading. I am sure I am not alone. Let the market decide if it's quicker and let us find out for ourselves if it will quit crashing on humongous projects instead of feeding us all the reasons it won't be. I'm tired of the thing crashing during every thea render and I don't want to break my projects up into pieces old technology can handle, and I'm tired of excuses, and I'm really tired of script writers who don't want to rewrite their scripts for 64 bit. If music and video programs can do it and Thea Render could do it, sketchup can certainly do it. If not for performance, for mere market appeal.
