I have 13.5 now in windows 7 drawing works in Dolphincad and when i send it to machining mill module the cam package opens but the drawing doesnt show the direction arrows do show when you hover over them , I have tried to figure out if a setting is wrong, but can not get the drawing to show up. Therefore can not pick a function even if I assign tool and try to assign functions still no drawing. It will say while assigning a function such as contoure or go-round, even though you assign an end mill and spec it out , you click ok it says you cant use that function you must use an end mill ?
