I suppose you need a full circle. First mark four points N,S,E,W of
column correctly. If possible,weld a very small 1/8" steel hook or
drill a tiny hole at center of H-column. Draw arc of circle, as much
as it is possible not obstructed by flange of H-sectioned beam. (They
can be cut/filled up later on).For the remaining part transfer from
the already drawn circle using cardboard or canvas or thick paper.
