CIRCLE+
This drawing tool allows the user draw a circle on the floor plane or a face using three
points. Note that the Sketchup circle tool requires two points: the center and radius. This,
however, is not helpful when tracing the 2D footprint of a column since the center of a column
in the photo may not be visible. However, the user can see half of the column and three
extreme outer points on the circle’s arc.
