Class Dxf

Creates a line segment definition for DXF (pass-through for validation). Example: start=[0,0], end=[10,5] → DXF line segment from origin to [10,5]

Creates an arc segment definition for DXF (curved path between two points). Example: center=[5,5], radius=5, startAngle=0°, endAngle=90° → quarter circle arc

Creates a circle segment definition for DXF (closed circular path). Example: center=[10,10], radius=5 → full circle with diameter 10 centered at [10,10]

Creates a polyline segment definition for DXF (connected line segments through points). Example: points=[[0,0], [5,0], [5,5], [0,5]] → rectangular polyline path

Creates a spline segment definition for DXF (smooth curve through control points). Example: controlPoints=[[0,0], [5,10], [10,0]] → smooth curved path through points

Creates a path from multiple segments (combines lines, arcs, circles, polylines, splines). Similar to OCCT wires - segments are connected to form a continuous or multi-part path. Example: segments=[lineSegment, arcSegment, polylineSegment] → combined path entity

Creates a paths part with layer and color assignment for DXF organization. Groups multiple paths into a single layer with consistent styling. Example: paths=[path1, path2], layer="Outlines", color=red → grouped geometry

Generates a complete DXF file from paths parts (exports 2D CAD drawing format). Supports lines, arcs, circles, polylines, and splines organized in layered paths. Example: model with 3 parts on different layers → valid DXF file string for CAD software
