SolidShell

Description

This is a component that generates shell deposition toolpaths from a closed solid geometry. It allows you to configure detailed settings such as the starting position, spacing, height, and tilting degree of the target planes. If the geometry is large, it can export the operation data by dividing it into partitions.

Input

Name	Type	Description
Geometry	Geometry	Target geometry for slicing. Accepts Brep or Mesh.
Reference Plane	Plane	Reference plane for slicing. Set parallel to the build plate direction. Layers are generated along the Z-axis of the plane. Default: WorldXY.
Seams	Curve	Guide curve that determines the starting point (Seam) position for each layer’s outer contour path. The intersection between the curve and the outer path is set as the layer starting point.
Edges	Curve	Guide curve used to tilt target planes formed around the geometry’s edges along the edge’s tangent direction.

Required Parameter

Name	Type	Description
Setback	Number	Inner/outer offset distance (mm) of the shell path relative to the input geometry boundary.
Shell Count	Integer	Number of shell paths to generate along the outer boundary of the input geometry.
Layer Width	Number	Width of a single deposition path (bead width, mm).
Layer Height	Number	Height of a single deposition layer (layer thickness, mm).
First Layer Height	Number	Height of the first deposition layer contacting the build plate (mm).
Tolerance	Number	Approximation tolerance for the path.

Name	Type	Description
Tilt Weight	Number	Weight to tilt the target Z-axis toward the surface slope (overhang) direction in overhang geometries. Used to align the torch or extruder with the surface inclination.
Edge Tilt Weight	Number	Weight to tilt targets toward the tangent direction of the edge in geometries with edges. Edge reference curves utilize the component’s Edges input.
Edge Tilt Ramp	Number	Distance (mm) to blend the Edge Tilt effect. Gradually applies and releases Edge Tilt over this distance before and after the edge to smooth path movements caused by sudden edge tangent direction changes.
Incremental Tilt Steps	Number	Number of layers (N) to gradually reach the configured Tilt Weight. Applies tilting step-by-step starting from initial layers near the build plate to prevent collisions and excessive robot motion caused by abrupt initial tilting.

Name	Type	Description
Wipe Distance	Number	Nozzle wiping distance. • Positive (+): Continues past the outer path completion point by the specified distance with an overlapping path. • Negative (-): Terminates early before the outer path end point by the specified distance.
Seam Spread	Number	Distributes seam start points across N cycles to prevent seams from concentrating at a single location. Shifts path parameters by 1/N per layer and returns to the original position every N layers. • Example: N = 4 → Layer 1 = 0.0, Layer 2 = 0.25, Layer 3 = 0.75, Layer 4 = 0.0 (repeating).
Seam Offset	Integer	Offset to collectively adjust the seam positions of all layers. Uniformly shifts the entire structure while maintaining relative positions between layers set by Seam Spread.

Partition

Name	Type	Description
Part Count	Integer	Number of parts to divide and slice the model into. • 1: Slices the entire model. / • N: Divides the model into N parts for partial slicing.
Part Number	Number	Part number (1 to N) to be sliced among the N divided parts.

Output

Name	Type	Description
Shell ToolPaths	Shell ToolPaths	Generated deposition toolpath data.
Shell Profile	Shell Profile	Reference profile information of the generated outer deposition paths.
First Part	Boolean	Flag indicating whether the current Deposition ToolPath is the bottom-most (first) part.
Shell Contours	Curve	Polylines connecting the generated outer deposition paths.
