With the pet palette’s Curve edge function, you can curve a segment of a straight element - such as a wall or beam - by dragging its edge or reference line.
Note: If the bent segment of a polygon intersects any of the other polygon edges, ARCHICAD will regularize the polygon’s shape, which may result in cutting the polygon into several parts.
To straighten a curved element edge, select the curved element, then select the Insert New Node command from the pet palette.
For more information on editing curved elements, see Stretching Curves.
