This function allows workings to be applied with the currently mounted milling cutter to the selected cut, whether a curve or a line, in order to create drain board flutes.

Parameters

The result varies depending on the value of the following parameters:

Number of drain board flutes	Indicates how many drain board flutes are to be applied to the current working on the selected cut. NOTE This parameter is visible only when the number-based drain board flute insertion mode is selected.
	Recalculate number Recalculates the number of drain board flutes to fill the selected cut. NOTE This parameter is visible only when the number-based drain board flute insertion mode is selected.
Length	Indicates how far the drain board flutes will extend into the cut.
Distance	This value represents the distance between the drain board flutes and takes the diameter of the mounted tool into account.
Start Distance	This value defines the distance between the vertices of the drain board flutes inside the piece, adjusting the empty space that separates them.
Internal extension	Indicates how far the drain board flutes will extend beyond the reference cut.
Start depth	Penetration into the material at the starting point of the drain board flute.
Final depth	Penetration into the material at the end point of the drain board flute.
Drain board flute type on arcs	Three modes are available for drain board flutes on curves, as shown below. NOTE This parameter is visible only when a curved cut is selected.
Cut thickness	For drain board flutes inserted in disk mode, the cut thickness variable is available. NOTE This parameter is visible only when disk mode is selected for inserting drain board flutes.
Overlay on Drip System	For drain board flutes inserted in fill mode, the percentage can be changed. NOTE This parameter is visible only when fill mode is selected for inserting drain board flutes.

Recalculate number

Pressing the button to the right of the number of drain board flutes fills the selected cut with as many drain board flutes as possible, according to the values of the other parameters.
The following example image shows the result of filling with drain board flutes, in contrast to the first image at the beginning of the chapter.

Drain board flute insertion mode

The drain board flute insertion options are:

	Insertion by number The drain board flutes are inserted according to the entered number. NOTE If this insertion method is selected, fill insertion cannot be used, and vice versa.
	Fill insertion The drain board flutes are inserted according to the entered distance.
	Disk mode The disk is used to cut the drain board flutes. NOTE If this mode is selected, milling cutter mode cannot be used, and vice versa.
	Milling cutter mode The milling cutter is used to cut the drain board flutes.

Drain board flute mode on arcs

When a curved cut of a polygon is selected, a new parameter is displayed and must be set to one of three values:

	Radial The drain board flutes are arranged along the curve so that they point towards the centre of the arc.
	Arc alignment The drain board flutes are arranged parallel along the curve and have equal length.
	Tangent alignment The drain board flutes are arranged parallel along the curve. Their length varies so that all ends inside the piece lie on the same line, while respecting the extension of the ends outside the piece.

Mode 1: Radial

In this mode, the drain board flutes share an origin point and are perpendicular to the corresponding tangent on the selected curved cut.

Mode 2: Arc alignment

In this mode, the drain board flutes are parallel to each other and arc-aligned for both the distance and the internal extension.

Mode 3: Tangent alignment

In this mode, the drain board flutes are parallel to each other and arc-aligned for the internal extension, while they are extended until they reach the tangent at the distance specified by the length value.

Executing the working

Once the desired result has been obtained, displayed and continuously updated in the working preview, the operator can confirm the operation by pressing the green “OK” button located just below the set parameters.
The drain board flutes shown in the preview are then applied to the selected cut: their colour changes to dark green, both in the preview and subsequently in the work area, indicating that they have been applied.

The cut list on the left is also updated according to the newly applied working and the drain board flute parameters.
Multiple workings of this type can be applied to a single cut, provided their parameters are not repeated.
