Path Cavidade Shape
|Localização do menu|
|Path → Pocket Shape → Cavidade|
This tool creates a pocketing operation from selected bottom faces or walls of one ore more pockets of the jobs base object.
The Path Pocket Shape object is made to be part of a Path Job.
- Select the bottom or the wall(s) of a pocket. While it is usually easier to select the bottom, the walls have to be selected when a pocket goes through all.
- Invoke the Pocket Shape command using several methods:
- Pressing the button in the toolbar.
- Using the then keyboard shortcut.
- Using the → entry from the top menu.
- Adjust the desired properties
Note : Not all of these Properties are available in the Task Window Editor. Some are only accessible in the Data tab of the Properties View panel for this Operation.
Note: It is suggested that you do not edit the Placement property of path operations. Rather, move or rotate the Path Job model as needed.
- DataPlacement: Overall placement[position and rotation] of the object - with respect to the origin (or origin of parent object container)
- DataAngle: Angle in degrees applied to rotation of the object around Axis property value
- DataAxis: Axis(one or multiple) around which to rotate the object, set in sub-properties: x, y, z
- DataX: x axis value
- DataY: y axis value
- DataZ: z axis value
- DataPosition: Position of the object, set in sub-properties: x, y, z - with respect to the origin (or origin of parent object container)
- DataX: x distance value
- DataY: y distance value
- DataZ: z distance value
- DataLabel: User-provided name of the object (UTF-8)
- DataClearance Height: The height needed to clear clamps and obstructions
- DataFinal Depth: Final Depth of Tool- lowest value in Z
- DataFinish Depth: Maximum material removed on final pass. The height (thickness) of the last cutting level - set for a better finish.
- DataSafe Height: The height above which Rapid motions are allowed. (Rapid safety height between locations)
- DataStart Depth: Starting depth of Tool - first cut depth in Z
- DataStep Down: Incremental step down of Tool during operation
Visual reference for Depth properties (settings)
- DataExtension Corners: When enabled connected extension edges are combined to wires.
- DataExtension Length Default: Default length of extensions.
- DataOffset Pattern: Clearing pattern to use. (Select in which manner the horizontal movements should be done.)
- DataActive: make False, to prevent operation from generating code
- DataComment: An optional comment for this Operation
- DataUser Label: User assigned label
- DataTool Controller: Defines the Tool controller used in the Operation
- DataCut Mode: Specifies a CW or CCW move for the cut
- DataExtra Offset: Extra offset to apply to the operation. Direction is operation dependent. (Extra value to stay away from final profile- good for roughing toolpath)
- DataKeep Tool Down: Attempts to avoid unnecessary retractions.
- DataMin Travel: Use 3D Sorting of Path (when multiple base geometries used).
- DataStart At: Start pocketing at center or boundary
- DataStep Over: Select the horizontal step over (Percent of tool diameter: 100% = tool diameter)
- DataUse Outline: Uses the outline of the base geometry.
- DataZig Zag Angle: Angle of the zigzag pattern. (Select the path angle relative to X axis.)
- DataAttempt Inverse Angle: Automatically attempt Inverse Angle if initial rotation is incorrect.
DataB_Axis Error Override: Visually orient B(y) rotations to model (error in FreeCAD rendering).
- DataEnable Rotation: Enable rotation to gain access to pockets or areas not normal to Z axis.
- DataInverse Angle: Inverse the angle of the rotation. Example: change a rotation from -22.5 to 22.5 degrees.
- DataReverse Direction: Reverse orientation of Operation by 180 degrees.
- DataStart Point: The start point of this path
- DataUse Start Point: make True, if manually specifying a Start Point, then enter Start Points in the property data Start Points field

Descriptions for the settings are provided in the Properties list above. This section is simply a layout map of the settings in the window editor for the Operation.
- Add: adds selected element(s) which should be the base(s) for the path(s)
- Delete: delete the selected item(s) in the Base Geometry list
- Clear: clear all items in the Base Geometry list
- DataShow All: If selected, all potential extensions are visualized. Enabled extensions in purple, disabled extensions in yellow.
- DataExtension Corners
- DataExtension Length Default
- DataStart Depth
- DataFinal Depth
- DataStep Down
- DataSafe Height
- DataClearance Height
- DataTool Controller
- DataCut Mode
- DataPattern (Offset Pattern)
- DataAngle (Zig Zag Angle)
- DataStep Over Percent (Step Over)
