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:
