Descriere

Traiectoria de prelucrare din forme nu se potrivește cu fluxul curent de lucru Path. Din acest motiv, este mutat la funcții experimentale.

Acest instrument generează traiectorii de unelte de la marginile unui obiect Path.

Traiectoria uneltelor nu sunt compensate pentru raza sculei. Nici un controler de unelte nu este asociat cu traiectoriile de unelte generate.

Utilizare

Toate muchiile asociate cu selecția Modelului 3D vor fi incluse.

Selectați muchiile prin selectarea întregului obiect din vizualizarea 3D sau din arborescența document, sau prin selectarea muchiilor individuale, sau a Fațetelor din vizualizarea 3D
apăsați butonul From Shape

Traiectoria de ieșire a sculei este adăugată în afara traiectoriei de lucru.

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).

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

sort_mode(1): 0=None,1=2D5,2=3D,3=Greedy. Wire sorting mode to optimize travel distance.
- '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'.

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

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

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

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

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

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

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

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

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

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

feedrate(0.0): Normal move feed rate.

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

verbose(true): If true, each motion G-code will contain full coordinate and feedrate.

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

preamble(true): Emit preambles.

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

Example:

shapes = [Box.Shape]
Path.fromShapes(shapes, start=Vector(), return_end=False, arc_plane=1, sort_mode=1, min_dist=0.0, abscissa=3.0, nearest_k=3, orientation=0, direction=0, threshold=0.0, retract_axis=2, retraction=0.0, resume_height=0.0, segmentation=0.0, feedrate=0.0, feedrate_v=0.0, verbose=True, abs_center=False, preamble=True, deflection=0.01)
