Parameters	Description
Shape	Choice between a single, double, or quadruple D-hole.
Diameter	Diameter of the D-hole
Width	Width of the single D-hole = diameter minus height of the recessed circle segment width of double and quadruple D-holes = diameter minus two times the height of the recessed circular segments
Height	Height of the quadruple D-hole = diameter minus two times the height of the two circular segments recessed at the top and bottom.
Rotation angle	Rotation angle of the D-hole around its reference point.
Tool	The 3 mm cutter is set by default. To produce smaller inner radii, uncheck the box next to Automatic selection (this may result in higher costs due to tool changes).
Cut after surface finishing	Only for powder-coated panels. Check the box next to this option if the D-hole is to be made after powder-coating. Additional information.
