Path FromShapes/fr

Description
Parcours d'usinage à partir de formes ne correspond pas au flux de travail Path actuel. Pour cette raison, il est déplacé vers les fonctionnalités expérimentales.

Cet outil génère des parcours d'outils à partir des bords d'un objet Parcours.

Les parcours d'outils ne sont pas compensés pour le rayon d'outil. Aucun contrôleur d'outil n'est associé aux parcours d'outils générés.



Utilisation
Toutes les arêtes associées à la sélection du modèle 3D seront incluses.
 * 1) Sélectionnez les arêtes en sélectionnant l'objet entier à partir de la vue 3D ou de l'arborescence du document, ou en sélectionnant des arêtes individuelles, ou par Faces à partir de la vue 3D.
 * 2) Appuyez sur le bouton

Le parcours d'outil est ajouté en dehors du travail de Path.

Options
Toutes les options fournies sont disponibles uniquement à partir de la vue FromShape.Property.Data et incluent:
 * Axe de rétraction
 * Hauteur de rétraction
 * Reprendre la hauteur
 * Vitesse d'avance
 * Vitesse d'avance verticale

DocString Info
Returns a Path object from a list of shapes


 * shapes: input list of shapes.


 * start (Vector): feed start position, and also serves as a hint of path entry.


 * return_end (False): if True, returns tuple (path, endPosition).

If not 'None', the output wires will be transformed to align with the selected plane, and the corresponding GCode will be inserted. 'Auto' means the plane is determined by the first encountered arc plane. If the found plane does not align to any GCode plane, XY plane is used. 'Variable' means the arc plane can be changed during operation to align to the arc encountered.
 * arc_plane(1): 0=None,1=Auto,2=XY,3=ZX,4=YZ,5=Variable. Arc drawing plane, corresponding to G17, G18, and G19.

'2D5' explode shapes into wires, and groups the shapes by its plane. The 'start' position chooses the first plane to start. The algorithm will then sort within the plane and then move on to the next nearest plane. '3D' makes no assumption of planarity. The sorting is done across 3D space. 'Greedy' like '2D5' but will try to minimize travel by searching for nearest path below the current milling layer. The path in lower layer is only selected if the moving distance is within the value given in 'threshold'.
 * sort_mode(1): 0=None,1=2D5,2=3D,3=Greedy. Wire sorting mode to optimize travel distance.

algorithm see fits. Set to zero to disable wire breaking.
 * min_dist(0.0): minimum distance for the generated new wires. Wires maybe broken if the

The sampling is dong using OCC GCPnts_UniformAbscissa
 * abscissa(3.0): Controls vertex sampling on wire for nearest point searching


 * nearest_k(3): Nearest k sampling vertices are considered during sorting

'Normal' means CCW for outer wires when looking against the positive axis direction, and CW for inner wires. 'Reversed' means the other way round
 * orientation(0): 0=Normal,1=Reversed. Enforce loop orientation


 * direction(0): 0=None,1=XPositive,2=XNegative,3=YPositive,4=YNegative,5=ZPositive,6=ZNegative. Enforce open path direction

as connected. You may want to set this to the tool diameter to keep the tool down.
 * threshold(0.0): If two wire's end points are separated within this threshold, they are consider


 * retract_axis(2): 0=X,1=Y,2=Z. Tool retraction axis


 * retraction(0.0): Tool retraction absolute coordinate along retraction axis

value of the next move.
 * resume_height(0.0): When return from last retraction, this gives the pause height relative to the Z

so that more correction points can be inserted
 * segmentation(0.0): Break long curves into segments of this length. One use case is for PCB autolevel,


 * feedrate(0.0): Normal move feed rate


 * feedrate_v(0.0): Vertical only (step down) move feed rate


 * verbose(true): If true, each motion GCode will contain full coordinate and feedrate


 * abs_center(false): Use absolute arc center mode (G90.1)


 * preamble(true): Emit preambles

discretizing circular wires when you 'Explode' the shape for wire operations
 * deflection(0.01): Deflection for non circular curve discretization. It also also used for
