Every word the man said is true,,V23,V24 is great but i have to say V25 pro is the fastest and most capable of all of the versions in my opinion ,, i had to laugh when he said 1985, it was 1987 1st-year vo-tech for me,,,, ive tool pathed some pretty wild shapes and so far there hasnt been one thing bobcad couldnt toolpath,,V23 was my favorite at one time,V24 is excellent but i gotta admit V25 is the king, the 4th-axis portion is excellent,, just the opinion of a "hobbiest" !
