Technical Drawing Software
My colleague wants to make some technical drawings like the one shown here.
He did this with PowerPoint 2003 (yes..he did..!!) and MS Paint.
But its time consuming and he is looking for a better solution.
Something which will allow you to draw tubes, cylinders, cones, cubes etc and also let you fit one into another.
Of course, AUTO CAD might help...but he dont want to involve measurements into it and besides its expensive too.
Any low cost or free software that will be of use for this?
