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
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.
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.
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.
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.
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.
