A few years back before SolidWorks bought "ToolBox" from CimLogic and dropped ACAD from their support, the program was very handy for generating all kinds of parametric 3D holes, threads, drills, counterbores, countersink's & much more. Just fill in the blanks and place in the drawing, subtract from the solid and all done complete & accurate. All this in acad14 and 2000, now I have looked just about everywhere to find another program to do the same in 2004, not sure about "DX" can't find a thing. I don't want to go to Inventor just to easily put a tapped hole in a solid. Anyone know of another program. Gene
