With the import() and extrusion statements it is possible to convert 2D objects read from DXF files to 3D objects.

Linear Extrude[edit]

Example of linear extrusion of a 2D object imported from a DXF file.

linear_extrude(height = fanwidth, center = true, convexity = 10)
   import (file = "example009.dxf", layer = "fan_top");

Rotate Extrude[edit]

Example of rotational extrusion of a 2D object imported from a DXF file.

rotate_extrude(convexity = 10, twist = -fanrot)
   import (file = "example009.dxf", layer = "fan_side", origin = fan_side_center);

Getting Inkscape to work[edit]

Inkscape is an open source drawing program. Tutorials for transferring 2d DXF drawings from Inkscape to OpenSCAD are available here:

Description of extrude parameters[edit]

Extrude parameters for all extrusion modes[edit]

scale FIXME
convexity See 2D to 3D Extrusion
file The name of the DXF file to extrude [DEPRECATED]
layer The name of the DXF layer to extrude [DEPRECATED]
origin [x,y] coordinates to use as the drawing's center, in the units specified in the DXF file [DEPRECATED]

Extrude parameters for linear extrusion only[edit]

height The extrusion height
center If true, extrusion is half up and half down. If false, the section is extruded up.
twist The extrusion twist in degrees
slices FIXME
