hi got a circle, looking to find how to project a line with known radius from the circle center to the perimeter at an angle of 60degs? (although, the book I'm reading from is showing that the line of 60degs is 120degs from point '0' as far as I can see it...... I know it all ends up in the same place, but I dont know two things:::;
1)why my book is showing an angle of 60degs when in fact its 120degs from zero
2)how the heck I tell a/cad to draw a line from center of circle to a point 'x' amount of degrees for a radius length.
searched 'help', but got nowhere. ( too much other info offered, rather than sticking to an elemetary question.)
