Using the 2D Subsystem 編集

DXF押し出しによって、2次元のDXFファイルを読み込み3次元のオブジェクトへ変換が可能となる。

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);

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, twist = -fanrot);

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

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

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
