Precison arcs in Rhino 7?

how do I draw precise arc lengths (ie: 4.6258" or 16.915°) in Rhino 7 ??


Command _Arc, set center point, set start point (you can type a number and Enter to set the radius), then type in the angle - or - click the _Length option and type in the length.


thanks, huge help!! it’s clearly going to take me some time to learn the Rhino “vocabulary” to the point the help function actually provides help. my CAD vocabulary isn’t getting the job done…
