OpenSCAD User Manual/DXF Extrusion
||The text in its current form is incomplete.|
With the import() and extrusion statements it is possible to convert 2D objects read from DXF files to 3D objects.
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");
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
Inkscape is an open source drawing program. Tutorials for transferring 2d DXF drawings from Inkscape to OpenSCAD are available here:
- http://repraprip.blogspot.com/2011/05/inkscape-to-openscad-dxf-tutorial.html (Very simple)
- http://tonybuser.com/?tag=inkscape (More complicated, involves conversion to Postscript)

Description of extrude parameters
Extrude parameters for all extrusion modes
|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
|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|
