2D Modifiers

2D modifiers operate on vector-based geometry such as shapes, outlines, and text. They are typically used to prepare artwork for cutting, engraving, printing, or extrusion into 3D geometry.

These modifiers are often combined with text, shape, and preprocessing nodes to generate clean, production-ready 2D geometry.

Modifier	Description	Input
Align Shape	Aligns a 2D shape relative to the origin or another shape.	Inputs Target: The 2D shape to align. Alignment (X): Horizontal alignment. Options: left, middle, right. Alignment (Y): Vertical alignment. Options: top, middle, bottom. Reference: Optional second shape to align against. If omitted, aligns to origin. Offset (X): Horizontal offset applied after alignment. Offset (Y): Vertical offset applied after alignment. Outputs Shape: The aligned shape. Moved (X): Distance moved along X. Moved (Y): Distance moved along Y.
Contain Shape	Fits a 2D shape within a container defined by width and height, preserving SVG quality.	Inputs Target: The 2D shape to contain. Width (X): Container width. Ignored when Boundary is set to viewBox. Height (Y): Container height. Ignored when Boundary is set to viewBox. Mode: How the shape is scaled: Match (shrink or grow to fill), Shrink Only, Grow Only. Aspect Ratio:Maintain (preserve proportions) or Deform (stretch to fit). Relative: When enabled, scales relative to the object; when disabled, scales in world space. Outputs Shape: The contained and scaled shape.
Convert Shape to Mesh	Converts a 2D vector shape into a 3D geometry mesh.	Inputs Shape: The input shape. Precision: Determines how closely the mesh follows the shape outline. Higher precision generates more geometry. Use Relative Precision: When enabled, precision is calculated relative to the size of the shape. Max Arc Subdivision: Limits the number of subdivisions used for curved segments. Outputs Geometry: The generated 3D mesh. Precision Used: The effective precision value applied during conversion.
Group shapes	Groups two shapes (2D geometries) into a single shape.	Inputs First: The first shape. Second: The second shape. Outputs Shape: The grouped shape.
Merge Shapes	Merges multiple shapes into one shape. More flexible than Group Shapes as it supports merging more than two shapes at once.	Inputs Shapes (array): List of 2D shapes to merge. Add as many inputs as needed. Outputs Shape: The single merged shape.
Minimum Distance	Ensures a shape respects minimum spacing and geometric constraints (e.g. gaps, radii, angles), resulting in clean and manufacturable geometry.	Inputs Shape Input shape to process. Minimum Bridge Desired minimum distance between opposite edges on the inside of a polygon Minimum Gap Desired minimum distance between opposite edges on the outside of a polygon Maximum Fillet Radius Desired radius of fillet operation performed after this modifier Precision Required precision: calculation stops when maximum morphing displacement is less than precision Minimum Polygon Size Polygons with an approximate diameter smaller than this value are discarded Angle Threshold In Degrees Defines when corners are treated as sharp vs smooth, influencing how the shape is simplified and cleaned. Arc Subdivide Precision Controls how accurately curves are approximated during processing, balancing smoothness and performance. Max Arc Subdivide Length Limits segment length when subdividing curves to maintain consistent geometric quality. Auto Resample Automatically redistributes points along the shape Outputs Shape Processed geometry respecting the defined constraints.
Pre-process shape	Preprocesses a shape for usage in Twikbot. This includes closing open shapes, fixing polygon winding, and ensuring there are no overlapping polygons.	Inputs Shape: The given shape. Close: Closes open shapes. Fix Polygon Winding: Aligns misoriented polygons. Merge: Merges overlapping polygons. Background: Background fill color used during preprocessing. Rescale Width: Rescales the shape to a specific width. Rescale Height: Rescales the shape to a specific height. Rescale Aspect Ratio: Determines how aspect ratio is handled during rescaling. Boundary: Defines the boundary type used for preprocessing (e.g. Bounding Box). Arc Subdivision: Controls subdivision accuracy for curved segments. Max Arc Subdivision: Maximum number of subdivisions applied to arcs. Outputs Shape: The processed shape.
Render text	Creates a 2D geometry from text combined with a font.	Inputs Target Text: The text to render as a shape. This can be provided as a fixed value or via a text input parameter. Font: The font used to generate the text outline. Text Size (mm): Controls the overall size of the text. Text Overlap (mm): Adjusts spacing between characters. Center Text: Centers the rendered text. Unify Text: Combines all characters into a single shape instead of separate shapes. Spacing Fixed: Uses the fixed spacing defined by the font. Fluent: Uses the minimum distance between characters based on horizontal spacing. Tight: Uses the bounding box of each character. Horizontal Spacing (mm): Horizontal distance between characters. Vertical Spacing (mm): Vertical distance between lines or shapes. Minimum Desired Bridge (mm): Desired minimum distance between opposite edges inside a polygon. Bridge Angle Threshold: Angle threshold used when calculating minimum desired bridges. Minimum Desired Gap (mm): Desired minimum distance between opposite edges outside a polygon. Gap Angle Threshold: Angle threshold used when calculating minimum desired gaps. Textbox Width (mm): Maximum width of the rendered text. Characters exceeding this width are clipped. Minimum Polygon Size (mm): Smallest polygon size allowed inside characters. Smaller polygons are removed. Outputs Geometry: The rendered text geometry. Clamped Text: The text output after applying the textbox width. This represents the actual text that remains visible when the text is clipped by the available textbox width.
Rotate Shape	Rotates a 2D shape by a given angle.	Inputs Shape: The 2D shape to rotate. Angle: Rotation angle in degrees. Relative: When enabled, rotation is around the object’s own center; when disabled, rotation is in world space. Outputs Shape: The rotated shape.
Round Corners	Rounds sharp corners of a shape by applying inner and outer radii, improving smoothness and manufacturability.	Inputs Shape Input shape to process. Inner Radius Radius applied to concave (inner) corners. Outer Radius Radius applied to convex (outer) corners. Rounding Angle Threshold Defines which angles are considered corners and should be rounded. Arc Subdivide Precision Controls smoothness of generated arcs. Max Arc Subdivide Length Maximum segment length for arc subdivision. Outputs Shape Shape with rounded corners applied.
Scale Shape	Scales a 2D shape along the X and/or Y axis.	Inputs Shape: The 2D shape to scale. X: Scale factor along X. Y: Scale factor along Y. Relative: When enabled, scales relative to the object’s own center; when disabled, scales in world space. Outputs Shape: The scaled shape.
Shape dimensions	Provides the overall dimensions of a shape.	Inputs Source Input shape. Outputs Width Total width of the shape. Height Total height of the shape.
Shape path count	Returns the number of paths (closed or open contours) in a shape.	Inputs Source Input shape. Outputs Count Number of paths in the shape.
Translate Shape	Moves a 2D shape along the X and/or Y axis.	Inputs Shape: The 2D shape to translate. X: Distance to move along X. Y: Distance to move along Y. Outputs Shape: The translated shape.
