I like that it's easy enough so as an average person, you can use guidedesign without any problems at all! It has saved me time when inserting implants since they are placed exactly where i want them with much less effort than if using traditional methods (screws). The only thing about this program would be its price tag but considering how powerful/easy toolbox 2 works compared too - not sure why anyone wouldn't consider buying both programs? This does everything needed by most people who needs bone grafting or placement etc.. The best thing about guidedesign, it's speed! It can be used with any platform (CAD/CAE), without problems or limitations that could slow you down at work day after days during your projects' development phases when using other softwares like Solidworks / Creo etc.. I have no complaints so far from my experience developing several dental prosthesis cases - only good things coming out this toolbox!!
