The 'Split' function allows to cut the piece using the reference, the side, a perpendicular line or a customized line.
The interface for this function resembles the following image:

Parameters

To use this working, it is necessary first to choose one of the three available modes, selecting the corresponding button:

	Parallel cut Selecting this mode, the cut for the division will be made along the longitudinal axis of the selected side.
	Orthogonal Cut Selecting this mode, the cut for the division will be performed obliquely with respect to the selected side, with the starting point coinciding with the center of the same side.
	Cut passing through two points Selecting this mode, the cut for division is defined by manually specifying the coordinates of the two extreme points that determine the separation line between the pieces.

Parameters for 'Parallel Cut' and 'Orthogonal Cut'

For the next two buttons below there is the possibility to enable or not this function clicking on the checkbox on the right of the writing 'Extension cut'.

Parameters for 'Through cut for two points'

For the next key there is the possibility to go to define the coordinates of the two points that constitute the division line.

Setting parameters points line of division	Upon activation of the function, four parametric fields will be available in which the operator can specify the coordinates (X, Y) of the initial and final points of the cutting line.
	Cutting orientation Through the pressure of the dedicated command, the user has the possibility to choose the cut orientation, horizontal, vertical or free, with respect to the starting point of the previously set line.
	Corner hooking When you select the free cut in the previous parameter, an additional parameter is displayed to its right that, if activated, facilitates the intercepting of the vertices of the figure for the definition of the cutting line points.

Execution working

Parallel cut

In the following image a parallel cut has been executed on the piece already visualized in the cover of the chapter:

Orthogonal cut

In the following image a cut orthogonal has been executed on piece already visible in cover of chapter:

Cut through two points

In the following image has been executed a through cut for two points using the hooking function of the vertices on the piece already visible in the cover of the chapter:

In the following image a cut through has been done for two points without using any particular function on the piece already displayed in the cover of the chapter:

Division of pieces

When to the selected piece one or more pieces have been associated through Division workings, a specific button for the management of the associated pieces appears in the upper part of the 'Modify Piece' panel.

	Split pieces Button that allows to separate the pieces divided from the original piece.

Before the split, the associated pieces are managed in a unified way inside the work area. In this state, a block composed of multiple elements is created that will undergo the same operations, without yet being divided.

For example, when one of the pieces generated through division is added to the working area from the piece list, also all the other associated elements are automatically inserted.

At the pressure of the button Divide Pieces, each piece generated through divide will be dissociated from the original piece and treated as an independent element.

Subsequently, both the list of pieces associated, previously visible above the preview in the Edit piece panel, and the button for the division of pieces will disappear from the interface.
