OpenSCAD User Manual/DXF Extrusion

The text in its current form is incomplete.

With the DXF Extrusion statements it is possible to convert 2D DXF files directly to 3D Objects.

Linear Extrude

With the DXF Extrusion statements it is possible to convert 2D objects to 3D objects.

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

Rotate Extrude

A rotational extrusion is a Linear Extrusion with a twist, literally.

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

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

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

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
slices	FIXME
